POWER switch @.
In off (up) position, supplies standby 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.
RESET button @.
Resets display and internal count to zero and arms counter for a new
measurement.
When continuously depressed, lights all segments of the LED display and all
annunciator LED's for LED test. Returns 5328A to LOCAL control when Option 011, HP-IB
Interface is in use.
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.
