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 40 ns to 1 us. The maximum duty cycle is 0.4%. 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 1Ω 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 1Ω 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. This instrument is intended for use in research and development laborat ories. __________________________________________________________________ 6 SPECIFICATIONS Model1: AVOZ-A2-B Amplitude2,3: current: 0 to 50A voltage: 0 to 50V Minimum load impedance4: 1Ω (required to limit current) Pulse width (FWHM): 40 ns - 1 us Rise time (20%-80%): ≤ 30 ns Fall time (80%-20%): ≤ 10 ns Maximum PRF: 20 kHz Duty cycle: (max) 0.4 % Output impedance: ≤ 0.1 Ω Average output power: 10 Watts maximum Droop: ≤ 5%, at maximum pulse width and maximum amplitude Polarity5: Positive or negative or dual polarity (specify) GPIB & RS-232 control1: Standard on -B units.

P OWER Switch . This is the main power switch. When turning the instrum ent on, there may be a delay of several seconds before the instrument appears t o respond. 2. O VERLOAD Indicator . When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an int ernal automatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low imped ance), the protective circuit will disable the output of the instrument and turn t he indicator light yellow. The light will stay yellow (i.e. output disabled) for about 5 s econds after which the instrument will attempt to re-enable the output (i.e. light g reen) for about 1 second. If the overload condition persists, the output will be disabl ed again (i.e. light yellow) for another 5 seconds. If the overload condition has been removed, the instrument will resume normal operation. This overload indicator may flash yellow briefly at start-up. This is n ot a cause for concern. Note that the output stage will safely withstand a short-circuited load condition. 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 > 1 kΩ with a pulse width of approximately 100 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 “Programming Manual for -B Instruments” describes the menus and submenu s in detail. __________________________________________________________________ 13 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. __________________________________________________________________ 14 REAR PANEL CONTROLS 4 1 3 5 7 GATE TRIG RS-232 OUT P OUT N AMP GPIB 8 6 9 10 2 1. A C POWER INPUT . An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. O ne end of the detachable power cord that is supplied with the instrument plugs in to this socket. 2. A C FUSE DRAWER . The two fuses that protect the AC input are located i n this drawer. Please see the “FUSES” section of this manual for more informat ion. 3. D C FUSES . These two fuses protect the internal DC power supplies. Ple ase see the “FUSES” sections of this manual for more information. 4. 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). When set to active high mode, this inp ut is pulled- down to ground by a 1 kΩ resistor. When set to active low mode, this in put is pulled- up to +5V by a 1 kΩ resistor. 5. 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 triggers on the rising edge of this input. The input impedance of this input is 1 kΩ. (Dependi ng on the length of cable attached to this input, and the source driving it, it m ay be desirable to add a coaxial 50 Ohm terminator to this input to provide a proper trans mission line termination. The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thr u 50 Ohm terminator is suggested for this purpose.) When triggering externally, the instrument can be set such that the out put pulse width tracks the pulse width on this input, or the output pulse width c an be set independently. __________________________________________________________________ 15 6. G PIB Connector . A standard GPIB cable can be attached to this connect or to allow the instrument to be computer-controlled. See the “Programming Manual f or -B Instruments” for more details on GPIB control. 7. 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 “Programming Manual for -B Instruments” for more details on RS-232 cont rol. 8. A MP Connector . (Active on units with the -EA option only.) The output amplitude can be set to track the voltage on this input. Zero Volts in corresponds to zero amplitude output, and +10V in corresponds to maximum amplitude out. This mode is activated by selecting "Ext Control" on the front-panel amplitude menu, or with the "source:voltage external" command. 9. O UT P . This is the main positive output, present on “-P” and “-PN” un its. It is only active when the amplitude is set to a positive value. The LZ1 transmiss ion line plugs into this socket. The upper side of the socket (“UP”) is the signal lin e. The lower side (“DOWN”) is connected to ground. 10. O UT N . This is the main negative output, present on “-N” and “-PN” un its. It is only active when the amplitude is set to a negative value. The LZ1 transmiss ion line plugs into this socket. The upper side of the socket (“UP”) is the sign al line. The lower side (“DOWN”) is connected to ground. __________________________________________________________________ 16 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: 100 ns, FIXED SYNC OUT (generated by the 3V, 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: 100 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY < 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Basic Output Pulses for Delay < 0 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: __________________________________________________________________ 17 > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 100 ns, FIXED SYNC OUT 3V, FIXED DELAY > 0 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.) 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 __________________________________________________________________ 18 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. __________________________________________________________________ 19 GENERAL INFORMATION - OPERATING INTO A LOAD 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. More specifically: IOUT = (VSETTING – VDIODE) / R, 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 between 1Ω and 1.6Ω; it should not be smaller than this. Avtech recommends connect ing multiple Ohmite OX or OY-series or RCD RSF2B resistors in parallel to create a h igh-power, low-inductance effective resistance. SELECTING THE SERIES RESISTANCE The best waveforms will be obtained if the amplitude is set between 20% and 100% of the maximum rating (i.e., 10V to 50V), and if the load resistance R is chosen to be between 1.0 and 1.6 Ohms. It should never be less than 1.0 Ω, or the instrument may be damaged. For applications requiring less than the maximum possible current, best results may be obtained if R is approximately 1.6 Ω, because this slight increase in t he load resistance will result in a faster transition times. However, the load resistance should not be increased beyond 1.6 Ω, or the transmission line mismatch between the o utput transmission line (which has a characteristic impedance of Z0 = 1 Ω) an d the load may introduce significant ringing. If the resistance of the device under test (DUT) is significantly highe r than 1.6 Ω, resistance should be added in parallel with the DUT so that the total e quivalent resistance is 1.6 Ω. TEST ARRANGEMENT The recommended test arrangement is shown below: __________________________________________________________________ 20 SCOPE DIODE PROBE (DEVICE AVOZ PULSER REAL-TIME UNDER TEST) SERIES OSCILLOSCOPE RESISTOR (RTOTAL = 1.6Ω) MAIN OUTPUT CHANNEL A CONNECTOR GROUND PAD OUTPUT AC PAD PROTECTION POWER DIODE (TO PREVENT REVERSE BIAS) SYNC TRIG OUTPUT INPUT NOTE: BOTH DIODES ARE SHOWN ORIENTED FOR A POSITIVE OUTPUT. REVERSE BOTH DIODES FOR NEGATIVE OPERATION. There are several key points to note. As explained above, a resistance should be added in series with the diode load, to limit the maximum current. This resistance may also be used to monitor the current through the diode current. If conne cted as shown above, the resistor voltage displayed on the oscilloscope is directly p roportional to the diode current. It is essential the low-inductance resistors be used. Se veral non- inductive, medium power resistors should be used in parallel (for insta nce, three 4.7 Ohm 2W resistors). The Ohmite OY series (www.ohmite.com) or the RCD RSF 2B series (www.rcd-comp.com) are appropriate. It is also recommended that a low-capacitance, medium-voltage, ultra-fa st Schottky rectifier diode be connected for reverse-bias protection, especially fo r sensitive or costly devices under test. The 1N5819 is an example of a suitable diode. Note, however, that the capacitance added by the protection diode may degrade the output ri se time slightly. USING THE LZ OUTPUT LINE A flexible, low-characteristic-impedance transmission line is supplied with this instrument. One end plugs into the front-panel OUT connector, and the o ther end is terminated with a 1.0 × 2.5 cm section of glass epoxy circuit board. Th e end that plugs into the front panel is marked with an “UP” side and a “DOWN” side. (Th e UP side is the signal output, and the DOWN side is ground.) It is critically important that the “UP” side of the line be visible. The load may be soldered to the circuit board end. The circuit board la yout is illustrated below: __________________________________________________________________ 21 UNUSED PAD LZ CABLE OUT GROUND PAD PAD The length of leads used to connect the load to the circuit board shoul d be kept extremely short ( < 0.5 cm), as discussed below. 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 changing at a rate given by dILOAD/dt (in Amps/sec), is: VSPIKE = L × d ILOAD/dt. For this reason, the length of leads used to connect the load to the ci rcuit board should be kept extremely short ( < 0.5 cm). 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. __________________________________________________________________ 22 START-UP CHECK-LIST FOR LOCAL CONTROL 1) Install a 1.6 Ω, 10 Watt test load between the signal out and ground pads on the LZ1 circuit board. (Factory tests are conducted using three 4.7 Ω, 2 Wa tt resistors connected in parallel.) 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 5 V/div, and the hori zontal scale to 100 ns/div. 4) Turn on the instrument.

ELECTROMAGNETIC INTERFERENCE To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded 50Ω loads using shielded 50Ω coaxial cables. U nused outputs should be terminated with shielded 50Ω coaxial terminators or w ith shielded coaxial dust caps, to prevent unintentional electromagnetic radiation. All cords and cables should be less than 3m in length. __________________________________________________________________ 25 MAINTENANCE REGULAR MAINTENANCE This instrument does not require any regular maintenance. On occasion, one or more of the four rear-panel fuses may require repla cement. All fuses can be accessed from the rear panel. See the “FUSES” section for details. CLEANING If desired, the interior of the instrument may be cleaned using compres sed air to dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for instructions on accessing the interior.) No other cleaning is recommend ed. __________________________________________________________________ 26 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. __________________________________________________________________ 27 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.)
