Performance Tests Option 011
6. Receiver Channel Noise Floor Level (Only for Analyzers with Option 006)
Receiver Channel B Noise Floor Level with a 3 kHz IF BW
(50 kHz3 GHz)
18 Press AVG, IF BW, 3, k/m to change the IF bandwidth to 3 kHz.
19 Press MENU, TRIGGER MENU, SINGLE.
20 When the analyzer finishes the sweep, record the mean value, which appears
on the analyzer display.
21 Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 * [log10(linear magnitude mean value)]
22 Write this calculated value in the Performance Test Record in dBm.

(3 GHz6 GHz)
23 Press START, 3, G/n, STOP, 6, G/n.
24 Press MENU, TRIGGER MENU, SINGLE.
25 When the analyzer finishes the sweep, record the mean value, which appears
on the analyzer display.
26 Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 * [log10(linear magnitude mean value)]
27 Write this calculated value in the Performance Test Record in dBm.
Receiver Channel B Noise Floor Level with 10 Hz IF BW
(3 GHz6 GHz)
28 Press AVG, IF BW, 10, x1 to change the IF bandwidth to 10 Hz.
29 Press MENU, TRIGGER MENU, SINGLE.
30 When the analyzer finishes the sweep, record the mean value, which appears
on the analyzer display.
31 Use the following equation to convert the linear magnitude mean value to log
magnitude:
Power (dBm) = 20 * [log10(linear magnitude mean value)]
