The current and voltage polarities depend on the model number: "-P" units: 0 to +50 V amplitude (0 to +50 Amps) "-N" units: 0 to -50 V amplitude (0 to -50 Amps) "-PN" units: 0 to 50 V amplitude (0 to 50 Amps) The pulse repetition frequency can vary from 1 Hz to 20 kHz, and pulse widths can vary from 20 ns to 1 s. The maximum duty cycle is 0.4%, and the maximum ave rage output power is 10 Watts. The Model AVOZ-A2-B pulse generator is a voltage pulser. The current am plitude is determined by Ohm’s Law. That is, the current is the output voltage div ided by the load resistance. The load resistance should be approximately 1 to attain a peak current of 50 A. The loads can be connected to the pulse generator using the convenient LZ1 flexible flat transmission line, which has a 1 characteristic impedance (Z0), a nd is terminated with a small circuit board. The AVOZ-A2-B can be controlled from the front panel, or via a computer connected to the IEEE 488.2-compliant GPIB port, or the RS-232 serial port. __________________________________________________________________ 6 SPECIFICATIONS Model: AVOZ-A2-B Amplitude: "-P" units: 0 to +50V into 1 (0 to +50A) "-N" units: 0 to -50V into 1 (0 to -50A) "-PN" units: 0 to 50V into 1 (0 to 50A) Pulse width: 20 ns to 1 s Rise time:  10 ns Fall time:  10 ns PRF: 1 Hz to 20 kHz Max. duty cycle: 0.4% Output impedance:  0.1 Ohms Propagation delay:  100 ns (Ext trig in to pulse out) Jitter:  100 ps (Ext trig in to pulse out) Trigger required: Internal PW Mode: +5 Volt, 50 ns or wider (TTL) (external trigger mode) Sync delay: Sync out to pulse out: Variable 0 to  1 us Sync output: + 3 Volts, 200 ns, will drive 50 Ohm loads Connectors: Out: solder terminals on the end of 60 cm flexible microstrip Trig, Sync, Gate: BNC Power, AC: 120/240 Volts (switchable) 50 - 60 Hz Temperature range: + 10 to + 40 C __________________________________________________________________ 7 INSTALLATION VISUAL CHECK After unpacking the instrument, examine to ensure that it has not been damaged in shipment. Visually inspect all connectors, knobs, liquid crystal displa ys (LCDs), and the handles. Confirm that a power cord, a GPIB cable, a LZ1 flexible transm ission line, and two instrumentation manuals (this manual and the “OP1B Interface Programming Manual”) are with the instrument. If the instrument has been damaged, file a claim immediately with the company that transported the instrument. PLUGGING IN THE INSTRUMENT Examine the rear of the instrument. There will be a male power receptacle, a fuse holder and the edge of the power selector card visible. Confirm that th e power selector card is in the correct orientation. For AC line voltages of 110-120V, the power selector card should be ins talled so that the “120” marking is visible from the rear of the instrument. For AC line voltages of 220-240V, the power selector card should be ins talled so that the “240” marking is visible from the rear of the instrument. If it is not set for the proper voltage, remove the fuse and then grasp the card with a pair of pliers and remove it. Rotate horizontally through 180 degrees. Reins tall the card and the correct fuse. In the 120V setting, a 1.0A slow blow fuse is required. In the 240V set ting, a 0.5A slow blow fuse is required. LABVIEW DRIVERS A LabVIEW driver for this instrument is available for download at the A vtech web site, at http://www.avtechpulse.com/labview. A copy is also available in Nationa l Instruments' Instrument Driver Library at http://www.natinst.com/. __________________________________________________________________ 8 FRONT PANEL CONTROLS 1. P OWER Switch . The POWER push button switch applies AC prime power to the primaries of the transformer, turning the instrument on. The push butto n lamp (#382 type) is connected to the +15V DC supply. 2. O VERLOAD . This instrument is protected in its internal software again st conflicting or dangerous settings. As an additional protective measure, an automati c overload circuit exists, which controls the front panel overload light. If the u nit is overloaded (for instance, by operating at an exceedingly high duty cycle or by ope rating into a very low impedance), the protective circuit will turn the output of the instrument OFF and turn the indicator light ON. The light will stay ON (i.e. output OF F) for about 5 seconds after which the instrument will attempt to turn ON (i.e. light OFF) for about 1 second. If the overload condition persists, the instrument will turn OF F again (i.e. light ON) for another 5 seconds. If the overload condition has been rem oved, the instrument will turn on and resume normal operation. This overload indicator may come on briefly at start-up. This is not a cause for concern. 3. S YNC OUT . This connector supplies a SYNC output that can be used to t rigger other equipment, particularly oscilloscopes. This signal leads, or lags , the main output by a duration set by the "DELAY" controls and has an approximate amplitude of +3 Volts to RL > 1k with a pulse width of approximately 200 ns. 4. L IQUID CRYSTAL DISPLAY (LCD) . This LCD is used in conjunction with th e keypad to change the instrument settings. Normally, the main menu is di splayed, which lists the key adjustable parameters and their current values. The “OP1B Interface Programming Manual” describes the menus and submenus in detai l. __________________________________________________________________ 9 5. K EYPAD . Control Name Function MOVE This moves the arrow pointer on the display. CHANGE This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. 10 If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten. 10 If one of the adjustable numeric parameters is displayed, this decreases the setting by a factor of ten. +/- If one of the adjustable numeric parameters is displayed, and this parameter can be both positive or negative, this changes the sign of the parameter. EXTRA FINE This changes the step size of the ADJUST knob. In the extra- fine mode, the step size is twenty times finer than in the normal mode. This button switches between the two step sizes. ADJUST This large knob adjusts the value of any displayed numeric adjustable values, such as frequency, pulse width, etc. The adjust step size is set by the "EXTRA FINE" button. When the main menu is displayed, this knob can be used to move the arrow pointer. __________________________________________________________________ 10 REAR PANEL CONTROLS 1. A C POWER INPUT . A three-pronged recessed male connector is provided o n the back panel for AC power connection to the instrument. Also contained in this assembly is a slow-blow fuse and a removable card that can be removed a nd repositioned to switch between 120V AC in and 240V AC in. For AC line voltages of 110-120V, the power selector card should be ins talled so that the “120” marking is visible from the rear of the instrument. For AC line voltages of 220-240V, the power selector card should be ins talled so that the “240” marking is visible from the rear of the instrument. If it is not set for the proper voltage, remove the fuse and then grasp the card with a pair of pliers and remove it. Rotate horizontally through 180 degrees. Reinstall the card and the correct fuse. In the 120V setting, a 1.0A slow blow fuse is required. In the 240V set ting, a 0.5A slow blow fuse is required. 2. D C FUSE . These slow-blow fuses protect the internal DC power supplies . 3. G ATE . This TTL-level (0 and +5V) logic input can be used to gate the triggering of the instrument. This input can be either active high or active low, dep ending on the front panel settings or programming commands. (The instrument triggers normally when this input is unconnected). 4. T RIG . This TTL-level (0 and +5V) logic input can be used to trigger t he instrument, if the instrument is set to triggering externally. The instrument trigg ers on the rising edge of this input. 5. G PIB Connector . A standard GPIB cable can be attached to this connect or to allow the instrument to be computer-controlled. See the “OP1B Interface Progr amming __________________________________________________________________ 11 Manual” for more details on GPIB control. 6. R S-232 Connector . A standard serial cable with a 25-pin male connecto r can be attached to this connector to allow the instrument to be computer-contr olled. See the “OP1B Interface Programming Manual” for more details on RS-232 cont rol. 7. O UT P . This is the main positive output, present on “-P” and “-PN” un its. The LZ1 transmission line or the RG174 transmission line plugs into this socket . The upper side of the socket (“UP”) is the signal line. The lower side (“DOWN”) i s connected to ground. 8. O UT N . This is the main negative output, present on “-N” and “-PN” un its. The LZ1 transmission line or the RG174 transmission line plugs into this socket . The upper side of the socket (“UP”) is the signal line. The lower side (“DOWN”) i s connected to ground. __________________________________________________________________ 12 GENERAL INFORMATION - PULSE GENERATOR TIMING BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an ext ernal TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC. The OUT channel is the signal that is applied to the device under test. Its amplitude and pulse width are variable. The SYNC pulse is a fixed-width TTL-level ref erence pulse used to trigger oscilloscopes or other measurement systems. When the de lay is set to a positive value the SYNC pulse precedes the OUT pulse. In the diagrams below, positive amplitude is assumed. (For “-N” units, the output waveforms are inverted in polarity.) These pulses are illustrated below for a positive delay, and internal t riggering: 200 ns, FIXED SYNC OUT (generated by the 2 V, FIXED internal oscillator) DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Basic Output Pulses for Delay > 0 The order of the output pulses is reversed for negative delays: 200 ns, FIXED SYNC OUT (generated by the 2 V, FIXED internal oscillator) DELAY < 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Basic Output Pulses for Delay < 0 __________________________________________________________________ 13 When the triggering is set to external mode, a TTL-level pulse on the T RIG input will trigger the pulse generator, as shown below: > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 200 ns, FIXED SYNC OUT (generated by the 2 V, FIXED internal oscillator) DELAY PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT As before, if the delay is negative, the order of the SYNC and OUT puls es is reversed. TRIGGER MODES This instrument has four trigger modes:  Internal Trigger: the instrument controls the trigger frequency, and ge nerates the clock internally.  External Trigger: the instrument is triggered by an external TTL-level clock on the back-panel TRIG connector.  Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE” pushbutton.  Hold Trigger: the instrument is set to not trigger at all. These modes can be selected using the front panel trigger menu, or by u sing the appropriate programming commands. (See the “OP1B Interface Programming Manual” for more details.) __________________________________________________________________ 14 GATING MODES Triggering can be suppressed by a TTL-level signal on the rear-panel GA TE connector. The instrument can be set to stop triggering when this input high or lo w, using the front- panel gate menu or the appropriate programming commands. This input can also be set to act synchronously or asynchronously. When set to asynchronous mo de, the GATE will disable the output immediately. Output pulses may be truncate d. When set to synchronous mode, the output will complete the full pulse width if the output is high, and then stop triggering. No pulses are truncated in this mode. __________________________________________________________________ 15 GENERAL INFORMATION - OPERATING INTO A LOAD BASIC TEST ARRANGEMENT The equipment should be connected in the general fashion shown above. Since the AVOZ unit provides an output pulse rise time as low as 10 ns a fast osc illoscope (at least 300 MHz) should be used to display the waveform. Proper choice of test resistance is important. It is essential that the resistive test load be low-inductance. (Wirewound resistors are not acceptable, unless many ar e connected together in parallel.) The power dissipated in the resistor is given by 2 PW PAVERAGE  I  R  , P 2   T PEAK I R where “I” is the current, “R” is the resistance, “PW” is the pulse widt h, and “T” is the pulse period (1/frequency). The power rating of the resistance should e xceed this average power rating by a large margin. Beware that some low-value resi stors exhibit a significant temperature-dependence, even when the average power dissipa ted is below the resistor’s power rating. This is particularly true if the peak powe r exceeds the resistor’s power rating. CONNECTING THE LOAD The loads can be connected to the LZ1 flexible flat transmission line, which has a 1 characteristic impedance (Z0), and is terminated with a small circuit b oard. The diode load and a non-inductive load resistor should be solder conne cted to the end of the line as shown below (using extremely short lead lengths (eg. 0.2 cm) so as to __________________________________________________________________ 16 reduce inductance). The series combination of the laser diode and the load resistor RL should present 1 to the end of the line. The instrument generates up to 50 Volts to provide a peak load current of 50 Amperes. For many diodes, a load res istor 1 may be selected as a first choice. An ultra fast rectifier diode may be pla ced across the laser diode to protect against reverse transients. Note that the net load re sistance may be higher than 1 but in this case the peak current will be less than 50 A mperes. The end of the LZ1 line is illustrated below: In the above diagram, the diode is oriented for positive current flow. Reverse the diode for negative operation. The next diagram shows how ultrafast rectifier diodes may be added to p rotect the laser diode: Again, in the above diagram, the diodes are oriented for positive curre nt flow. Reverse all diodes for negative operation. AMPLITUDE CONTROL The Model AVOZ-A2-B pulse generator is a voltage pulser. The current am plitude is determined by Ohm’s Law. That is, the current is the output voltage div ided by the load resistance. __________________________________________________________________ 17 More specifically, , where VSETTING is the set amplitude, VDIODE is the diode voltage, and R is the series resistance (including any series resistance in the diode itself). R is normally 1; it should not be smaller than this. LENZ’S LAW AND INDUCTIVE VOLTAGE SPIKES This instrument is designed to pulse resistive and diode loads and will exhibit a large output spike when used to drive a load with significant inductance (as predicted by LENZ'S LAW). For this reason the load should be connected to the output using low inductance leads (as short as possible and as heavy a gauge as possible ). The voltage developed across an inductance L (in Henries), when the cur rent is dI changing at a rate given by dI LOAD LOAD/dt (in Amps/sec), is: V  L SPIKE . dt ATTACHING AND DETACHING LOADS To avoid damaging the loads connected to main outputs, the loads should only be connected to or removed from the instrument when the instrument is off. Do not connect loads when the instrument is on and the output amplitude is not zero. This can cause sparking. __________________________________________________________________ 18 START-UP CHECK-LIST FOR LOCAL CONTROL 1) Insert a 1 test load between the signal out and ground pads on the LZ1 circuit board. 2) Connect a cable from the SYNC OUT connector to the TRIG input of an oscilloscope. Set the oscilloscope to trigger externally. 3) Connect an oscilloscope probe to the signal side of the test load. O n the oscilloscope, set the channel A vertical scale to 20 V/div, and the hor izontal scale to 100 ns/div. 4) Turn on the instrument. The main menu will appear on the LCD. 5) To set the instrument to trigger from the internal clock at a PRF of 1 kHz:  The arrow pointer should be pointing at the frequency menu item. If i t is not, press the MOVE button until it is.  Press the CHANGE button. The frequency submenu will appear. Rotate th e ADJUST knob until the frequency is set at 1 kHz.  The arrow pointer should be pointing at the “Internal” choice. If it is not, press MOVE until it is.  Press CHANGE to return to the main menu. 6) To set the delay to 100 ns:  Press the MOVE button until the arrow pointer is pointing at the dela y menu item.  Press the CHANGE button. The delay submenu will appear. Rotate the AD JUST knob until the delay is set at 100 ns.  Press CHANGE to return to the main menu. 7) To set the OUT pulse width to 500 ns:  Press the MOVE button until the arrow pointer is pointing at the “PW” menu item.  Press the CHANGE button. The pulse width submenu will appear. Rotate the ADJUST knob until the pulse width is set at 500 ns. __________________________________________________________________ 19  The arrow pointer should be pointing at the “Normal” choice. If it is not, press MOVE until it is.  Press CHANGE to return to the main menu. 8) At this point, nothing should appear on the oscilloscope. 9) To enable the output:  Press the MOVE button until the arrow pointer is pointing at the outp ut menu item.  Press the CHANGE button. The output submenu will appear.  Press MOVE until the arrow pointer is pointing at the “ON” choice.  Press CHANGE to return to the main menu. 10)To change the OUT output amplitude:  Press the MOVE button until the arrow pointer is pointing at the AMP menu item.  Press the CHANGE button. The amplitude submenu will appear. Rotate th e ADJUST knob until the amplitude is set at 50 V (or -50V for “-N” units) .  Observe the oscilloscope. You should see 500 ns wide, 50V pulses on t he probe connected to the main output.  Press CHANGE to return to the main menu. 11)Try varying the pulse width, by repeating step (7). As you rotate th e ADJUST knob, the pulse width on the oscilloscope will change. It should agree with t he displayed value. 12)This completes the operational check.

With these four screws removed, the top panel may be slid off by pulling it towards the rear. RACK MOUNTING A rack mounting kit is available. The -R5 rack mount kit may be install ed after first removing the one Phillips screw on the side panel adjacent to the front handle. __________________________________________________________________ 21 CALIBRATION ADJUSTMENTS - SOFTWARE PROCEDURES ADJUSTING AMPLITUDE ACCURACY If it is found that the output amplitude settings (as set by the front- panel controls or programming commands) do not agree exactly with measured values of ampl itude (i.e., by examining the output on an oscilloscope), the amplitude calibration can be updated using software commands. The following procedure is suggested: 1) Connect a 1 high-power resistive load to the output. 2) Connect the pulse generator to a computer using the GPIB or RS232 po rts. 3) Turn on the pulse generator, and set the time controls (frequency, d elay, pulse width) to typical values. 4) Turn on the outputs. 5) Set the output amplitude to 50V. 6) Observe the voltage across the load. (For example, suppose it is 52V ). 7) Send the measured value to the instrument using the following comman d: diag:ampl:cal 52 The internal software compares the supplied measured value to the progr ammed value, and adjusts the internal calibration data to null out any differ ences. 8) Observe the voltage across the load again. The amplitude setting sho uld now agree with the measured value. Information on more extensive timing and amplitude calibration procedur es is available at http://www.avtechpulse.com/appnote/. __________________________________________________________________ 22 PROGRAMMING YOUR PULSE GENERATOR KEY PROGRAMMING COMMANDS The “OP1B Interface Programming Manual” describes in detail how to conn ect the pulse generator to your computer, and the programming commands themselv es. A large number of commands are available; however, normally you will only need a few of these. Here is a basic sample sequence of commands that might be sent t o the instrument after power-up: *rst (resets the instrument) trigger:source internal (selects internal triggering) frequency 10 Hz (sets the frequency to 10 Hz) pulse:width 100 ns (sets the pulse width to 100 ns) pulse:delay 1 us (sets the delay to 1 us) output on (turns on the output) source:volt 50V (sets the voltage amplitude to 50 Volts) For triggering a single event, this sequence would be more appropriate: *rst (resets the instrument) trigger:source hold (turns off all triggering) pulse:width 100 ns (sets the pulse width to 100 ns) output on (turns on the output) source:volt 50V (sets the voltage amplitude to 50 Volts) trigger:source immediate (generates a single non-repetitive trigger event) trigger:source hold (turns off all triggering) output off (turns off the output) To set the instrument to trigger from an external TTL signal applied to the rear-panel TRIG connector, use: *rst (resets the instrument) trigger:source external (selects internal triggering) pulse:width 100 ns (sets the pulse width to 100 ns) pulse:delay 1 us (sets the delay to 1 us) source:volt 50V (sets the voltage amplitude to 50 Volts) output on (turns on the output) These commands will satisfy 90% of your programming needs. __________________________________________________________________ 23 ALL PROGRAMMING COMMANDS For more advanced programmers, a complete list of the available command s is given below. These commands are described in detail in the “OP1B Interface Pr ogramming Manual”. (Note: this manual also includes some commands that are not im plemented in this instrument. They can be ignored.)
