Figure 2-22. 10 MHz Reference Adjustment (Option 003)/Setup and Adjustment Location

1.Connect equipment as shown in Figure 2-22 as follows:

a.Set the (LINE) switch of the spectrum analyzer to on. After the automatic power-on adjustment sequence is complete, press (PRESET) to ensure that the frequency reference is set to internal.

b.Allow the spectrum analyzer to remain powered on continuously for at least 24 hours to ensure that both the temperature and frequency of the A21 OCXO can stabilize.

c.Connect the frequency standard to the frequency counter’s rear panel TIMEBASE IN/OUT connector as shown in Figure 2-22.

d.Connect a BNC cable between the 10 MHz REF IN/OUT jack on the spectrum analyzer rear panel and INPUT A on the frequency counter.
