    4) Keep in mind that all cables, connectors, oscilloscope probes, and loads must have an appropriate voltage rating. Do not attempt any repairs on the instrument, beyond the fuse replacement procedures described in this manual. Contact Avtech technical support (see page 2 for contact information) if the instrument requires servicing.

    If interference is observed, check that appropriate well-shielded cabling is used on the output connectors. Contact Avtech (info@avtechpulse.com) for advice if you are unsure of the most appropriate cabling. Also, check that your load is adequately shielded. It may be necessary to enclose the load in a metal enclosure.

    FRONT PANEL CONTROLS 1. POWER Switch . This is the main power switch. When turning the instrument on, there is normally a delay of 10 seconds before anything is shown on the main display, as the internal operating system boots up. If the main menu does not appear after 30 seconds, turn off the instrument and leave it off for at least 60 seconds before applying power again.

  • Page 20 When triggering externally, the instrument can be set such that the output pulse width tracks the pulse width on this input, or the output pulse width can be set independently. 6. GPIB Connector . A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled.

  • Page 21: General Information

    GENERAL INFORMATION BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an external 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 load. Its amplitude and pulse width are variable.

  • Page 22: Trigger Modes

    > 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 Figure C As before, if the delay is negative, the order of the SYNC and OUT pulses is reversed. 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.

    Ground Ground AV-HLZ1-100 CABLE One AV-HLZ1-100 cable is provided with the AVOZ-E3-B. One end of the cable mates to the rear-panel OUT connector. The cable is specially designed to have a transmission line characteristic impedance ) of approximately 1 Ohm, to minimize distortions and reflections.

  • Page 26: Av-Hlza1 Test Load / Adapter

    AV-HLZA1 TEST LOAD / ADAPTER An AV-HLZA1 test load / adapter is provided with the AVOZ-E3-B. When shipped from the factory, it is configured with five 2W resistors in parallel installed between the OUT and GROUND lines, for a total effective resistance of 1Ω (10W). Please note that it is not capable of dissipating the maximum average power that the AVOZ-E3-B can deliver (100 W).
