Performance Tests Option 011
6. Receiver Channel Noise Floor Level (Only for Analyzers with Option006)
5When the analyzer finishes the sweep, notice the mean value, which appears on
the analyzer display.
6Use the following equation to convert the linear magnitude mean value to log
amplitude:
Power (dBm) = 20 * [log10(linear magnitude mean value)]
7Write this calculated value in the Performance Test Record in dBm.
Receiver Channel A Noise Floor Level with a 10 Hz IF BW
(50 kHz3 GHz)
8Press AVG, IF BW, 10, x1 to change the IF bandwidth to 10 Hz.
9Press MENU, TRIGGER MENU, SINGLE.
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 * [log10(linear magnitude mean value)]
12 Write this calculated value in the Performance Test Record in dBm.
Receiver Channel B Noise Floor Level with 10 Hz IF BW
(50 kHz3 GHz)
13 Press MEAS, INPUT PORTS, B, FORMAT, LIN MAG.
14 Press MENU, TRIGGER MENU, SINGLE.
15 When the analyzer finishes the sweep, notice the mean value, which appears on
the analyzer display.
16 Use the following equation to convert the linear magnitude mean value to log
