-B, -C, -PS and Module Instrument formats
Most Avtech models are available in several of the following four formats:
-B Format: Stand-alone lab instrument with GPIB control. See Figure 1. A full description is available here. The programming manual is also available online.


-C Format: Stand-alone lab instrument including internal clock and line powering (120/240 Volts, 50-60 Hz, with detachable line cord). See Fig. 2. Standard controls generally include pulse width, amplitude, pulse repetition frequency, delay and sync output. Units may also be triggered externally using a slow speed TTL signal. GPIB control not available.


-PS Format: Line powered chassis (110/220 Volts, 50-60 Hz, with detachable line cord) requiring external slow speed TTL trigger signal. See Fig. 3. Output PRF equals input trigger PRF. Standard controls generally include pulse width and amplitude.


Module Format: DC powered miniature module (either +15 or +24V) requiring external TTL input trigger signal. See Fig. 4. Output PRF equals the input trigger PRF. Standard controls generally include output pulse width and amplitude.
