Equipment for the Periodic Adjustments Programs
• For the Timebase Reference Using a Counter calibration you will
need to connect a frequency counter to the rear-panel 10 MHz REF
OUTPUT connector. The accuracy of the counter will determine the
accuracy of the Test Set’s internal reference. You will use the counter
to set the timebase reference DACs.
• For the Timebase Reference Using a Source calibration you will
need to connect a signal generator to the front-panel ANT IN
connector.
• For the Voltmeter References calibration you will need a DC
voltmeter that can measure
±5 V with ±0.015% accuracy.
