6. Test Port Input Noise Floor Level
Power (dBm) = 20 * [log10(linear magnitude mean value)]
17 Write this calculated value on the "Performance Test Record."
Port 2 Noise Floor Level from 50 kHz to 3 GHz (IF BW= 3 kHz)
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, notice the mean value.
21 Convert the measured linear magnitude mean value to log magnitude, using
this equation.
Power (dBm) = 20 * [log10(linear magnitude mean value)]
22 Write this calculated value on the "Performance Test Record."
23 This completes the "Test Port Input Noise Floor Level" procedure if your
analyzer does not have Option 006. Otherwise, continue with the next section.
Port 2 Noise Floor Level from 3 GHz to 6 GHz (IF BW= 3 kHz)
24 Press START, 3, G/n, STOP, 6, G/n.
25 Press MENU, TRIGGER MENU, SINGLE.
26 When the analyzer finishes the sweep, notice the mean value.
27 Convert the measured linear magnitude mean value to log magnitude, using
this equation.
Power (dBm) = 20 * [log10(linear magnitude mean value)]
28 Write this calculated value on the "Performance Test Record."
Port 2 Noise Floor Level from 3 GHz to 6 GHz (IF BW= 10 Hz)
29 Press AVG, IF BW, 10, x1 to change the IF bandwidth to 10 Hz.
30 Press MENU, TRIGGER MENU, SINGLE.
31 When the analyzer finishes the sweep, notice the mean value.
32 Convert the measured linear magnitude mean value to log magnitude, using
this equation.
Power (dBm) = 20 * [log10(linear magnitude mean value)]
33 Write this calculated value on the "Performance Test Record."
