HP 75000 SERIES C User Manual

Frequency Accuracy
This procedure compares the accuracy of the HP E1440A output
signal to the specification.
Specifications
f 5 x
of selected frequency (20°C to 30°C).
Equipment Required
Electronic counter (calibrated within three months or with an
accurate 10
MHz external reference input)
Procedure
1. Connect the HP E1440A signal output to the electronic counter
channel A input with a 50R feedthru termination. Allow the
HP
E1440A to warm up for 30 minutes and the counter's frequency
reference to warm up for its specified period.
2. Set the
HP E1440A output as follows:
High-Voltage Output Off

3. Set the counter's gate time to 0.01 s to measure the frequency of
the A input with 0.1
Hz resolution. If necessary adjust the trigger
level for stable triggering. The electronic counter should indicate
20,000,000.00
Hz f 100 Hz.
4. Change the HP E1440A frequency 10 MHz. Change the function
to a square wave. The electronic counter should indicate
10,000,000.00
Hz f 50 Hz.

5. Change the HP E1440A frequency 10 kHz. Change the function
to a triangle. Set the counter's gate time to 0.1 s. The electronic
counter should indicate 100,000.00 ns
f 0.5 ns.

6. Change the HP E1440A function to a positive slope ramp. The
electronic counter should indicate 100,000.00 ns
f 0.5 ns.
