Performance Tests 8719ES/20ES/22ES
RF Network Analyzers
Level Accuracy Performance Test
This test checks the maximum variation in output power across the frequency range of the
analyzer.
Analyzer warmup time: 30 minutes.
1. Zero and calibrate the power meter.
2. Set the calibration factor on the power meter to the average value of the power sensor
between 50 MHz and 20 GHz (40 GHz for 8722ET/ES).
For example, if the power sensor calibration factor is 100% at 50 MHz and 92% at
20 GHz (40 GHz for 8722ET/ES), set the calibration factor to 96%.
3. Connect the equipment as shown in Figure 2-18.
