Description
Wavetek Model 23 12MHz Synthesized Function Generator IEEE-488 GPIB TTL ECL
The Wavetek Model 23 is a benchtop synthesized function generator capable of producing signals from 1 kHz up to 12 MHz. It features a digital LCD display for direct frequency and waveform readout, front-panel pushbutton control of frequency, period, mode, function, amplitude, and offset parameters, and a large rotary knob for value adjustment. The unit was manufactured in San Diego, California and is switchable for operation on line voltages from 100V to 240V.

Applications
Synthesized function generators like the Wavetek Model 23 are used in electronics labs, test benches, and R&D environments to generate precise, stable waveforms for circuit testing, component characterization, calibration, and frequency response analysis. The IEEE-488 GPIB interface allows this unit to be integrated into automated test systems and controlled programmatically via a GPIB controller, which was a standard configuration in 1980s–1990s ATE setups. The TTL and ECL outputs make it compatible with digital logic testing, while the VCG and AM inputs enable voltage-controlled frequency sweeping and amplitude modulation for more advanced signal applications. This type of instrument was commonly used in semiconductor, telecommunications, and university research environments.
This Wavetek Model 23 12MHz Synthesized Function Generator has been inspected and appears to be in good used condition. The front panel, controls, and connectors show the normal yellowing and light surface wear typical of benchtop lab equipment from this era. The LCD display is visible and appears intact. No major damage, cracks, or broken controls are observed. The rear IEEE-488 GPIB connector shows some surface oxidation on the mounting hardware, which is cosmetic. The unit was pulled from a working lab environment. Please view our photo set and contact us if you have any questions.
