Performance Verification Tests
34. Gain Compression: Agilent E4404B, E4405B, E4407B, and E4408B
less than or equal to 2.5 GHz. Use the directional coupler for higher
frequency measurements.

3. On the synthesized sweeper 1 press PRESET, then set the controls as
follows:
CW, 50 MHz
POWER LEVEL, –100 dBm
4. On the synthesized sweeper 2 press PRESET, then set the controls as
follows:
CW, 53 MHz
POWER LEVEL, –3 dBm
5. Enter the power sensor calibration factor for the synthesized
sweeper 2 frequency into the power meter.
6. Adjust the synthesized sweeper 2 power level setting until the power
meter reading is the same as indicated in Table 2-80.
7. Record the actual synthesized sweeper 2 power level setting in
