Spectracom 8131
The Spectracom 8131 is a frequency standard oscillator plug-in for the TM500 system.
From New Products, Electronics 1979-06-07:
Plugged into a TM500 mainframe, the model 8131 oscillator provides a stable output frequency that is selectable at 0.1, 1.0, 5.0, or 10 MHz. A digital front panel control permits resolution to within as little as 1 part in 1010.
The frequency output can be fed to a plug-in counter through a rear connector to provide it with an external time base. When used with a plug-in 8163 WWVB receiver, the resultant instrument is traceable to the National Bureau of Standards.
Use of a proportional oven control speeds oscillator warm up; use of the 8131 with the 8132 accessory battery power supply eliminates warmup. When the oscillator output is stable to within 2 parts in 108, a front-panel indicator lamp lights. The unit's temperature stability is within ±7 parts in 109 and it is designed to work from 0°to 55 °C.
