NOTE Note the mean value displayed on the analyzer is in µUnits. If the
displayed value is 62µU, the value you would put in the equation is
(62 x 10
−6
).
8. Write this calculated value on the performance test record.
Port 2A Channel Noise Floor Level from 300 kHZ to 3 GHz
(IF BW = 10 Hz)
1. Press Avg, IF BW, 10, x1 to change the IF bandwidth to 10 Hz.
2. Press Sweep Setup, TRIGGER MENU, SINGLE.
3. When the analyzer finishes the sweep, notice the mean value.
4. Convert the measuredlinear magnitude mean value to logmagnitude
using the following equation:
Power (dBm) = 20 x [log
10
(linear magnitude mean value)]
5. Write this calculated value on the performance test record.
Port 3 Noise Floor Level from 300 kHz to 3 GHz
(IF BW = 10 Hz)
1. Press Meas, INPUT PORTS, B, TESTPORT 1, Format, LIN MAG.
2. Press Sweep Setup, TRIGGER MENU, SINGLE.
3. When the analyzer finishes the sweep notice the mean value.
4. Convert the measuredlinear magnitude mean value to logmagnitude
using the following equation:
