Equipment

•10 MHz Primary Frequency or House Standard: HP 5071A (or equivalent)

•Terminal or computer (PC): Any Model with communication software and RS-232 connection

•HP 53131A Universal Counter (or equivalent)

Procedures

Determining Frequency Difference

The frequency difference is measured by synchronizing the frequency counter with a known standard and observing the 58502A frequency output to a resolution of at least 10 digits.

1Connect 10 MHz reference to HP 53131A Universal Counter’s (or equivalent) rear-panel external timebase (Reference) input as shown in Figure 2-7.

2Connect any output of the 58502A to the Counter’s input as shown in Figure 2-7.

3Set the Counter’s gate time to 1-second to display at least 10 digits (10,000,000.000).
