Performance Tests
6. Receiver Channel Noise Floor Level (Only for Analyzers with Option 006)
31.Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 × [log
10
(linear magnitude mean value)]
32.Write this calculated value in the performance test record in dBm.
Channel A Noise Floor Level with 10 Hz IF BW (3 GHz–6 GHz)
33.Press .
34.Press .
35.When the analyzer finishes the sweep, record the mean value, which appears on the
analyzer display.
36.Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 × [log
10
(linear magnitude mean value)]
37.Write this calculated value in the performance test record in dBm.
Channel A Noise Floor Level with 3 kHz IF BW (3 GHz–6 GHz)
38.Press .
39.Press .
40.When the analyzer finishes the sweep, notice the mean value, which appears on the
analyzer display.
41.Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 × [log
10
(linear magnitude mean value)]
42.Write this calculated value in the performance test record in dBm.
In Case of Difficulty
1. Perform “ADC Offset Correction Constants (Test 52)” on page 3-18.
2. Suspect the A10 digital IF assembly if both receiver channels fail.
3. Refer to Chapter 8 , “Receiver Troubleshooting,” for troubleshooting information.
