Tektronix 067-0532-01 Constant Amplitude Signal Generator

The Tektronix Type 067-0532-01 Calibration Fixture is a Constant Amplitude Signal Generator whose output is a low-distortion sinewave. It is intended to provide a signal of known frequency and amplitude for measuring oscilloscope bandwidth.

A 3 MHz sinewave is available as a reference amplitude from which a -3 dB measurement can be made. The output connector, amplitude detector, and 50 Ω source resistor are at the end of a 42 inch cable. The amplitude is regulated at the end of the cable adjacent to the GR-874 output connector, thus essentially eliminating cable loss and standing-wave errors.
