Wavetek Model 801 50MHz pulse Generator.

The Wavetek Model 801 is a 50 MHz pulse generator delivering five simultaneous outputs for precision timing and digital/analog circuit testing. It combines a variable-amplitude main pulse with fixed-level TTL, ECL, and sync outputs, offering independent control of rise and fall times across a 5 Hz to 50 MHz frequency range. Engineers and laboratories use this instrument for versatile pulse generation with selectable operational modes including continuous, triggered, gated, burst, double pulse, and external width control.

Technical Specifications

Primary Pulse Output (Variable Amplitude)

• ECL pulses: Two outputs with <6 ns transition times


• TTL pulses: One output with <10 ns transition times


• Sync pulse: 50% ±4% duty cycle (periods ≤2 µs)

Key Features

• Normal/complement control for all outputs except sync


• Six operational modes: continuous, triggered, gated, burst (1–100 pulses), double pulse, and external width


• Dual ECL outputs plus dedicated TTL and sync outputs


• Vernier adjustment on fast rise/fall times for precise control

Typical Applications Digital circuit timing, analog pulse testing, system integration verification, and laboratory characterization of high-speed circuits requiring precise trigger synchronization and multi-format logic outputs.

Compatibility & Integration Standard TTL and ECL logic levels ensure compatibility with conventional digital test equipment and circuit boards.
