2. Press .
3. Press (or if the analyzer has Option 006) and write the
frequency counter reading on the performance test record.
4. Repeat step 3 for each frequency listed in the performance test record.
In Case of Difficulty
1. If any measured frequency is close to the specification limits, check the time base
accuracy of the counter used.
2. If the analyzer fails by a significant margin at all frequencies (especially if the deviation
increases with frequency), the master time-base probably needs adjustment. In this
case, refer to “Frequency Accuracy Adjustment” on page 3-42. The “Fractional-N
Frequency Range Adjustment” on page 3-39 can also affect the frequency accuracy.
3. Refer to Chapter 7 , “Source Troubleshooting,” for related troubleshooting information.
