Figure 3-5. Frequency Response Test Setup
Procedure
1. Zero and calibrate the power meter and power sensor as described in the power meter
operation manual.
2. Configure the equipment as shown in Figure 3-5..
NOTE Connect the power splitter to the spectrum analyzer input using the
appropriate adapter. Do not use a cable.
3. Assure the spectrum analyzer’s built-in auto alignment has been performed within the
last 24 hours.
4. Preset (Factory Preset) both the spectrum analyzer and the synthesized sweeper.
5. Set up the synthesized sweeper by pressing:
CW, 50, MHz
Power level, –8, dBm
