The DataPulse 101 is a vintage benchtop pulse generator from the 1970s–80s era, engineered to produce precision TTL-compatible output signals across a 10 Hz to 10 MHz frequency range. This tested and functional instrument delivers adjustable pulse width, delay, and repetition rate through manual controls with vernier adjustment, supporting both single and double pulse modes. Output reaches +10 V amplitude with 5 ns rise time, accessible via BNC connector with selectable normal and complement outputs. External trigger capability operates from single-cycle to 10 MHz for ±0.4 V pulses (30 ns minimum) or 50 Hz to 10 MHz from 2 V RMS sine waves, enabling synchronous or asynchronous gated operation. Manual pushbutton triggering is available for single-cycle pulse generation. The instrument accepts external gate signals between +1 V and +10 V to enable or disable main pulse outputs, making it suitable for precision timing, pulse characterization, and synchronization tasks in test and educational settings.
