Performance Tests
5. Minimum R Channel Level
6Write the power meter reading in the "Results Measured" column on the
"Performance Test Record."
7Calculate the difference between the analyzer test port power (which appears
on the analyzer’s display) and the power meter reading. Write the result in the
"Power Level Linearity" column on the "Performance Test Record."
8Repeat Step 5 through Step 7 for the other power levels listed in the
"Performance Test Record."
9Press CW FREQ, 3, G/n.
10 Set the power meter calibration factor for this CW frequency and press REL to
set the reference at this new frequency.
11 Press MENU, POWER, –15, x1.
12 Write the power meter reading in the "Results Measured" column on the
"Performance Test Record."
13 Calculate the difference between the analyzer test port power and the power
meter reading. Write the result in the "Power Level Linearity" column of the
"Performance Test Record."
14 Repeat Step 11 through Step 13 for the other power levels listed in the
"Performance Test Record."
In Case of
Difficulty
1Ensure that the power meter and power sensor(s) are operating to
specifications. Be sure you set the power meter calibration factor for the CW
frequency that you are testing.
2Verify that there is power coming out of the analyzer’s test port 1. Be sure you
did not accidently switch off the analyzer’s internal source. If you did so, press
MENU, POWER, SOURCE PWR ON.
3Repeat this performance test.
5. Minimum R Channel Level
Perform this test to determine the minimum R channel input power level at
which phase lock can be accomplished.
