Option 001 High Stability Timebase Adjustment Procedure

1. Remove the instrument top cover. Power up the instrument and let it warm up for

approximately 1 hour.

2. Remove the rear-panel cable between the Opt. 001 REF OUT and REF IN connectors

(if present).

3. Attach a high accuracy frequency counter to the rear panel OPT 001 REF OUT. The

frequency counter resolution and accuracy should be at least 1 Hz at 10 MHz.

4. Adjust the high stability timebase (see figure 7-1) until the frequency counter reads 10

MHz.

NOTE After performing this calibration, it is necessary to install a cable from the OPT 001 REF

OUT to the REF IN connector for the instrument to use the high stability timebase as the

reference.
