10 MHz Frequency Reference Adjustment

This adjustment applies to analyzers with both the standard 10 MHz frequency reference and 10 MHz precision frequency reference (Option 1D5). Ensure that the analyzer has been powered on for at least 60 minutes before performing an adjustment.

The adjustment is performed by calculating the actual frequency error in Hz from Counter Reading 1 given in the previous 10 MHz Frequency Reference Accuracy test. The negative or positive error is then used to define what the new DAC setting should be. Once the DAC settings are adjusted and saved, the 10 MHz Frequency Reference Accuracy test is repeated to verify the unit meets its published specification.
