Wavetek 75 Arbitrary Waveform Generator Option 001 IEEE-488 GPIB TTL ARB Out

Wavetek 75 Arbitrary Waveform Generator Option 001 IEEE-488 GPIB TTL ARB Out

The Wavetek Model 75 is a benchtop arbitrary waveform generator (AWG) capable of generating user-defined waveforms as well as standard waveshapes. It features a front-panel alphanumeric LCD, dedicated function and menu keys, and a large rotary encoder for parameter entry. Option 001 adds the IEEE-488 (GPIB) interface for remote programmable control from a controller or PC. This unit is manufactured in the USA and accepts both 115V and 230V line voltages.

Applications

Arbitrary waveform generators like the Wavetek 75 are used in electronics R&D, component characterization, and automated test systems wherever a precisely shaped or custom waveform is needed. The AWG can reproduce real-world signals — modulated carriers, transients, noise bursts, or digitized waveforms — making it useful for testing amplifiers, filters, ADCs, DACs, and communications circuits. The GPIB interface (Option 001) allows the instrument to be integrated into IEEE-488 instrument buses common in 1980s and 1990s automated test equipment (ATE) racks alongside other GPIB-controlled instruments. The TTL trigger, sync, burst, and hold I/O lines enable precise coordination with oscilloscopes, counters, and other lab instruments. Wavetek was a well-regarded San Diego-based manufacturer of signal and waveform generators from the 1960s through the 1990s; the Model 75 dates from the mid-to-late 1980s era of benchtop GPIB instrumentation. These instruments remain in use today in legacy ATE environments and university/industrial labs that maintain GPIB-based instrument racks.
