Most Avtech models are available in several of the following four formats:
Stand-alone lab instrument with GPIB control. A full description is available here. The programming manual is also available online.
Stand-alone lab instrument including internal clock and line powering (100-240 Volts, 50-60 Hz, with detachable line cord). Standard controls generally include pulse width, amplitude, pulse repetition frequency, delay and sync output. Units may also be triggered externally using a TTL-level (Low = 0V, High = +3V to +5V) pulse. GPIB control is not available.
Line powered chassis (100-240 Volts, 50-60 Hz, with detachable line cord) requiring external slow speed TTL trigger signal. Output PRF equals input trigger PRF. Standard controls generally include pulse width and amplitude.
DC powered miniature module (+15 or +24V typically) requiring external TTL input trigger signal. Output PRF equals the input trigger PRF. Standard controls generally include output pulse width and amplitude.
