Frequency Standard 761

This instrument has been designed to fill the need for a self-contained compact frequency standard of moderate cost and very high accuracy.
Sine wave and pulse signals are produced at five standard frequencies, the pulse waveform being extremely rich in harmonics.
An oscilloscope, complete with X and Y amplifiers, is incorporated for visual frequency comparison, and a Beating circuit and loudspeaker for aural checking.
The instrument is enclosed in one of the Airmec range of cases which is suitable either for bench use or forward mounting on a 19in. rack.

• Master Oscillator: Crystal-controlled at a frequency of 100 kHz.
• Outputs: Outputs are provided at 100 Hz, 1 kHz, 10 kHz, 100 kHz and 1 MHz.
• Waveform: The above outputs are available simultaneously with sinusoidal or pulse waveform from separate plugs.
• Stability: Four hours after switching on a short-term stability of considerably better than 1 part in 10⁶ is obtained.
