Performance Tests
1. Connect the equipment as shown in Figure 1-8.
Figure 1-8 Port Output Frequency Range and Accuracy Test Setup
2. Press Preset, Sweep Setup, CW FREQ.
3. Press 30, k/m and write the frequency counter reading in 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 counter used.
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 standard
documentation for more information about frequency accuracy
adjustment. The “Fractional-N Frequency Range Adjustment” also
affects frequency accuracy.
