2. Press .
Channel A Noise Floor Level for 3 kHz IF BW (300 kHz–3 GHz)
3. Press .
4. Press
.
5. When the analyzer finishes the sweep, notice the mean value, which appears on the
analyzer display.
6. Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 × [log
10
(linear magnitude mean value)]
7. Write this calculated value in the performance test record in dBm.
Channel A Noise Floor Level for 10 Hz IF BW (300 kHz–3 GHz)
8. Press to change the IF bandwidth to 10 Hz.
9. Press .
10.When the analyzer finishes the sweep, notice the mean value, which appears on the
analyzer display.
11.Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 × [log
