In off (up) position, supplies power to oven of the Option 010 high
stability time base to maintain a constant temperature for the crystal.
In ON position,
supplies normal operating power to the instrument.
WARNING
THE AC POWER INPUT CIRCUITS TO TRANSFORMER
T1 AND THE UNREGULATED DC VOLTAGE ARE STILL
ON, EVEN WHEN THE POWER SWITCH IS OFF.

FUNCTION selector @. Selects mode of operation.
a.
RATIOC/A. Sets counter to measure the ratio of the frequency at channel C (Option 030
channel C installed) to the frequency at channel A.
CHECK. Applies 10 MHz to decade counting assemblies. Verifies operation of SAMPLE
RATE control, RESOLUTION
switch, and RESET.
FREQ C. Sets counter to measure the frequency at the channel C input.
DVM. Sets counter to measure the voltage applied to the terminals of the Option 020 or
021 digital voltmeter.
START A, STOP. Sets the counter to totalize the number of events at the A input until
STOP is selected, for N=1 on the RESOLUTION switch.
For N>1, the number of counts
divided by N is totalized. The scaled output (i.e., frequency of A+N) is available at the
Time Base Out rear panel connector.
