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 connector|GR-874 output connector]], thus essentially eliminating cable loss and standing-wave errors.
