Page 5: Introduction
INTRODUCTION The Model AV-107C-B pulse generator is designed for pulsing laser diode and other low impedance loads with rectangular pulses as high as 10 Amperes into load voltages up to 60V, with 20 ns rise and fall times. The pulse repetition frequency can vary from 1 Hz to 5 kHz, and pulse widths can vary from 100 ns to 1 us (or optionally 20 us). -
Page 6: Kmpa Option, -Pw1 Option
The AV-107C-B has two amplitude ranges, of 0 to 1A and 1 to 10A, allowing the instrument to be used at both moderate and high current levels. (The instrument automatically selects the appropriate range based on the amplitude setting.) The AV-107C-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. -

If the load cannot be placed directly on the output terminals of the -PG module, the AV- LZ lines should be used between the -PG module and the load (see the Avtech AV-LZ data sheet, available at www.avtechpulse.com). -

Beware that wirewound resistors usually have far too much inductance to be useful as current-sensing resistors. 4. The AV-107C-B includes a monitor output connector on the output module.

The SYNC pulse is a fixed-width TTL-level reference pulse used to trigger oscilloscopes or other measurement systems. When the delay is set to a positive value the SYNC pulse precedes the OUT pulse.

The delay, pulse width, and frequency (when in the internal mode), of the OUT pulse can be varied with front panel controls or via the GPIB or RS-232 computer interfaces. -
Page 23: Gating Modes
GATING MODES Triggering can be suppressed by a TTL-level signal on the rear-panel GATE connector. The instrument can be set to stop triggering when this input high or low, using the front- panel gate menu or the appropriate programming commands. This input can also be set to act synchronously or asynchronously. -
Page 24: Load Protection
LOAD PROTECTION 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). -

Page 42: Appendix A - Low-Value, Low-Inductance, High-Power Resistors
Connecting resistors in parallel reduces the total effective resistance and inductance. Avtech does not recommend the use of single, high-power resistors, even if they are low-inductance types. These resistors experience high failure rates in pulsed applications. -
