    It also features an exceptionally fast 300 ps rise and 350 ps fall times. The AV-1030-B is a highly flexible instrument. Aside from the internal trigger source, it can also be triggered or gated by external TTL-level signals. A front-panel pushbutton or a computer command can also be used to trigger the instrument.

    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.

  • Page 19: 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, four output channels respond to the trigger: OUT, SYNC, LOGIC, and LOGIC-Complement. • OUT. This is the main output. The pulse width and amplitude are adjustable. The maximum output voltage is ±5V.
  • Page 20 If the delay is negative, the order of the SYNC and OUT pulses is reversed: 50 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY < 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT +5V (TTL) or -0.8V (ECL) LOGIC OUTPUT 0V (TTL) or -1.6V (ECL) +5V (TTL) or -0.8V (ECL)

    TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) ≈ PW AMPLITUDE, VARIABLE MAIN OUTPUT +5V (TTL) or -0.8V (ECL) LOGIC OUTPUT 0V (TTL) or -1.6V (ECL) +5V (TTL) or -0.8V (ECL) LOGIC OUTPUT 0V (TTL) or -1.6V (ECL) 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: Pulse Width Modes

    PULSE WIDTH MODES This instrument has two pulse width modes: • Normal: the instrument controls the output pulse width. • PW : the output pulse width equals the pulse width of the trigger signal on the “TRIG” connector. The instrument must be in the external trigger mode. These modes can be selected using the front panel pulse width menu, or by using the appropriate programming commands.

    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 properly drive a high-impedance load.
