Maximum Leveled Power
This test measures the maximum power levels at different frequencies where the 2500B maintains power leveling.
NOTE:
When measuring the flatness and accuracy of the 2500B, consideration must be given to the various
measurement uncertainties in the test system. These include, but are not limited to, VSWR, Cal Factor uncertainty, and
linearity.

Step
Action
1.
Connect the equipment as shown in Figure 50 on page 106.
2.
Allow the equipment to warm up for at least 30 minutes.
3.
Set the 2500B to the first frequency specified in the datasheet, and press
.
4.
Increase the output power of the 2500B until the UNLEVELED indicator lights.
5.
Reduce the output power setting until the UNLEVELED indicator turns off.
6.
Record the measured maximum leveled output power in the datasheet for the test frequency.
7.
Repeat steps 3 through 6 for the remaining frequencies in the datasheet that are within the
operating range of the instrument.
8.
After entering all of the test results into datasheet, compare the results with the following to
verify compliance of the 2500B:
