2. Press .
3. Press and write the frequency counter reading on the performance test
record.
4. Repeat step 3 for each instrument 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 frequency 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 the “Frequency Accuracy Adjustment” on page 3-43. The “Fractional-N
Frequency Range Adjustment” on page 3-40 also affects frequency accuracy.
3. Refer to the Chapter 7 , “Source Troubleshooting,” if the problem persists.
