Setting the signal generators
This prepares the signal generators for output.
3.
Set the SG1 frequency to 200.00 MHz; the SG1 level to -10 dBm; and the SG1
output to ON.
4.
Set the SG2 frequency to 200.25 MHz; the SG2 level to -20 dBm; and the SG2
output to ON.
Initialization
This resets the current settings to the factory defaults.
5.
Press SHIFT and CONFIG(PRESET).
The default settings have now been reset.
Setting the measurement conditions
This changes the analyzer settings so that the input signal is displayed more clearly.
6.
Press FREQ, 2, 0, 0 and MHz.
A center frequency of 200 MHz is set.
7.
Press SPAN, 1, 0 and MHz.
A frequency span of 10 MHz is set.
The spectrums are not fully separated because the RBW default setting is 100 MHz.
As a result, the display shows only one input signal even though there are actually two.
