The manual for the Wavetek Model 157 Programmable Waveform Synthesizer provides detailed instructions on installation, manual operation, programming, and troubleshooting, including the use of various operational modes such as VCG with manual calibration, automatic calibration, trigger, and search modes. It also covers maintenance procedures, including checkout, calibration, and replacement of components, ensuring the device operates correctly and efficiently.
Overview
The Wavetek Programmable Waveform Synthesizer Model 157 is a precision instrument capable of generating sine, square, or triangle waveforms over a frequency range from 100 picohertz to 1 megahertz in 10 ranges. It offers output amplitudes from 1 millivolt to 10 volts peak-to-peak into a 50-ohm load. The device includes a voltage-controlled generator that allows frequency modulation with a 0-volt to 5-volt analog input. The synthesizer can be operated in four modes: VCG with manual calibration, automatic calibration, trigger, and search. It supports both front-panel and remote programming for frequency, amplitude, and function. The instrument is designed for rack mounting or bench operation.

Operation
The manual describes several modes of operation for the Wavetek Programmable Waveform Synthesizer Model 157. These modes include:
1. VCG with manual calibration: Selected at the front panel for accurate calibration of the output frequency, allowing the frequency to be swept about the calibrated center frequency with a VCG input.
2. Automatic calibration: Selected at the front panel or programmed from a remote source to provide an accurate fixed-frequency output by closed-loop operation.
3. Trigger mode: Selected at the front panel or programmed from a remote source, placing the device in a standby state until a positive pulse is applied. The standby state varies depending on the waveform type.
4. Search mode: Selected at the front panel for sweeping the entire selected frequency range to find a specific frequency, disabling digital programming of frequency.
5. VCG without manual calibration: Obtained in remote-control operation when none of the other functions are programmed, allowing manual sweeping of the frequency range with a front-panel control.
The instrument can be operated using front-panel pushbuttons or remotely through logic-level or contact-closure programming. It is designed for mounting in a standard 19-inch rack or for use on a test bench.
