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. 3) P RF Range Switch . This switch sets the pulse repetition frequency (PR F) range of the internal oscillator. The marked value of each position is the upper limit of the 10:1 range, approximately. The vernier dial directly below the switch v aries the PRF within the set range. If this switched is set to the “EXT” position, the instrument is trigge red by a signal applied to the TRIG connector, rather than by the internal oscillator. 4) T RIG Connector . When the PRF Range Switch is set to “EXT”, the instru ment is triggered by a TTL pulse applied to this connector. The pulse must be a t least 50 ns wide. When the PRF Range Switch is set to one of the four internal oscillator ranges, this __________________________________________________________________ 15 connector is an output, which supplies a 2V, 50 ns wide pulse for each trigger event. This output may be used to trigger oscilloscopes or other equipm ent. 5) D elay Controls . When the PRF Range Switch is set to one of the four i nternal oscillator ranges, the main output is advanced or delayed relative to t he TRIG output pulse (item 3). The delay is variable up to 200 ns, approximatel y, using the DELAY and DELAY FINE dials. 6) P ulse Width Control . This dial controls the pulse width. 7) A mplitude Control . This dial controls the amplitude. 8) O UT Connector . This connector provides the main output signal, into l oad impedances of 50Ω. (This output requires a 50Ω load to function properl y). 9) R ISE / FALL TIME Controls . (Optional. Requires -TRF option.) The rise and fall times can be switched between 0.15 and 1 ns, approximately, using these switches. 10) O FFSET Control . (Optional feature. Present on units with the -OT or - EO options only.) A DC offset in the range of -5V to +5V can be added to the outpu t using this control. The rear-panel “OFFSET ON/OFF” switch must be set to “ON” to e nable this feature. For -EO units, the rear-panel “OS INT/EXT” switch must al so be set to “INT” for this control to function. __________________________________________________________________ 16 REAR PANEL CONTROLS 1 3 4 M INT EXT A 5 PW 6 OFFSET AMP ON OFF OS 7 OS GND OFFSET OUT 8 9 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. M ONITOR Output (Optional, -M units only) . Provides an attenuated (÷1 0) coincident replica (to 50 Ohms) of the main output. 5. P W INT/EXT SWITCH AND CONNECTOR (Optional, -EW units only) . To contro l the pulse width of the output with an external DC voltage, set the two-posi tion switch to the EXT position and apply 0 to +10V to the BNC Connector (RIN ≥ 10 kΩ) . When this switch is in the “INT” position, the pulse width is controlled by the front-panel controls. 6. A MP INT/EXT SWITCH AND CONNECTOR (Optional, -EA units only) . To contr ol the amplitude of the output with an external DC voltage, set the two-po sition switch to the EXT position and apply 0 to +10V to the BNC Connector (RIN ≥ 10 kΩ). When this switch is in the “INT” position, the amplitude is controlled by th e front-panel controls. 7. O S INT/EXT SWITCH AND CONNECTOR (Optional, -EO units only) . To contro l the offset of the output with an external DC voltage, set the two-position switch to the EXT position and apply 0 to +10V to the BNC Connector (RIN ≥ 10 kΩ). Wh en this switch is in the “INT” position, the offset is controlled by the front- panel controls. __________________________________________________________________ 17 8. O S INPUT (For units without -OT or -EO options) . To add a DC offset t he output pulse, connect a DC power supply set to the desired offset value to the se terminals. The maximum allowable DC offset voltage is ±50 Volts, and the maximum D C current is 250 mA. When not used, this input should be connected to the adjacent ground terminal. 9. O FFSET ON/OFF SWITCH & OUTPUT (Optional, -EO and -OT units only) . Thi s switch enables the offset feature when it is set to “ON”. When it is se t to “OFF”, no offset is added to the output. The internally generated offset is avail able at the “OFFSET OUT” BNC connector, for monitoring purposes. To add an offset t o inverted pulses on AVMR-1-C units with the dual polarity option (-PN), connect this terminal to the DC terminal of the AVX-2-T inverting transformer (see t he “POLARITY INVERSION” sections in this manual for further details). __________________________________________________________________ 18 GENERAL INFORMATION BASIC TEST ARRANGEMENT The AVMR-1-C should be tested with a sampling oscilloscope with a bandw idth of at least 10 GHz to properly observe the high-speed waveform. A typical tes t arrangement is shown below: AVTECH SAMPLING PULSER OSCILLOSCOPE BW > 10 GHz MAIN OUTPUT 50 OHM INPUT CONNECTOR 40 dB AC ATTENUATOR POWER TRIG TRIG CONNECTOR CONNECTOR ALL CABLES: 50 OHM COAXIAL The attenuator is required to prevent damage to the sampling oscillosco pe. BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an ext ernal TTL trigger signal. When triggered internally, two mainframe output channels respon d to the trigger: OUT and SYNC.  OUT. This is the main output.  TRIG. The TRIG pulse is a fixed-width TTL-level reference pulse used to trigger oscilloscopes or other measurement systems. The TRIG output precedes the main output. These pulses are illustrated below: __________________________________________________________________ 19 200 ns, FIXED TRIG (generated by the 2V, FIXED internal oscillator) DELAY PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT When triggered externally, the TRIG connector acts as an input. The del ay controls do not function in this mode. This illustrated below: > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) PULSE WIDTH MAIN OUTPUT AMPLITUDE, VARIABLE AMPLITUDE INTERACTION Some properties of the output pulse may change as a function of the amp litude setting. For some demanding applications, it may be desirable to use a combinati on of external attenuators and the amplitude pot to achieve the desired output amplitu de. POLARITY INVERSION Instruments with the "-P-PN" suffix generate 0 to +10V at the main outp ut, and are supplied with an AVX-2 inverting transformer that can be installed on t he mainframe output. A negative pulse is then obtained at the out port of the AVX-2 module. Instruments with the "-N-PN" suffix generate 0 to -10V at the main outp ut, and are supplied with an AVX-2 inverting transformer that can be installed on t he mainframe output. A positive pulse is then obtained at the out port of the AVX-2 module. When using the transformer with dual-polarity models, the external offs et must be added to the DC terminal of the inverting transformer. Do not apply the offse t to the rear-panel offset terminal on the mainframe. For units with the OT or EO options, connect a lead __________________________________________________________________ 20 from the rear panel OS OUT connector to the DC terminal of the AVX-2-T unit. The DC offset at the output of the AVX-2-T unit is then controlled by the fron t-panel offset control. __________________________________________________________________ 21 MINIMIZING WAVEFORM DISTORTIONS USE 50 OHM TRANSMISSION LINES AND LOADS Connect the load to the pulse generator with 50Ω transmission lines (e. g. RG-58 or RG- 174 cable). This instrument requires a 50Ω load for proper operation. It will not p roperly drive a high-impedance load. The output stage will be damaged if it is operated into an open circuit (or any other high impedance). Failures due to improper output loading are not covered by the warranty. USE LOW-INDUCTANCE LOADS Lenz’s Law predicts that for an inductive voltage spike will be generat ed when the current through an inductance changes. Specifically, VSPIKE = L × dILOA D/dt, where L is the inductance, ILOAD is the load current change, and t is time. For th is reason, it is important to keep any parasitic in the load low. This means keeping wir ing short, and using low inductance components. In particular, wire-wound resistors sh ould be avoided. PREVENTING DAMAGE The AVMR-1-C may fail if triggered at a PRF greater than 10 MHz, or if the duty cycle exceeds 20%. This unit is designed to operate into a load impedance of 50 Ohms and t he output stage will be damaged if it is operated into an open circuit (or any other hi gh impedance). Failures due to improper output loading are not covered by the warranty . The lifetime of the switching elements in the pulse generator module is proportional to the running time of the instrument. For this reason the prime power to the instrument should be turned off when the instrument is not in use. __________________________________________________________________ 22 MECHANICAL INFORMATION TOP COVER REMOVAL If necessary, the interior of the instrument may be accessed by removin g the four Phillips screws on the top panel. With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpow ered for 10 minutes before opening the instrument. This will allow any internal sto red charge to discharge. There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech (info@avtechpulse.com) to arrange for the instrum ent to be returned to the factory for repair. Service is to be performed solely b y qualified service personnel. Caution: High voltages are present inside the instrument during normal operation. Do not operate the instrument with the cover removed. 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. ELECTROMAGNETIC INTERFERENCE To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded loads using shielded coaxial cables. Unused ou tputs should be terminated with shielded coaxial terminators or with shielded coaxia l dust caps, to prevent unintentional electromagnetic radiation. All cords and cables s hould be less than 3m in length. __________________________________________________________________ 23 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.)
