Figure6-7. Receiver Channel Noise Floor Level Test Setup
2Press PRESET, MENU, POWER, –10, x1.
Receiver Channel A Noise Floor Level with a 3 kHz IF BW
3Press MEAS, INPUT PORTS, A, FORMAT, LIN MAG, SCALE REF, AUTO SCALE.
4Press MARKER FCTN, MARKER MODE MENU, STATS ON, MENU, TRIGGER MENU, SINGLE.
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
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
