Signal generator settings (e.g. R&S SMW):
Level Frequency
Signal generator 1 -4 dBm 999.7 MHz
Signal generator 2 -4 dBm 1000.3 MHz
Setting up the measurement
1. Set the R&S FSVA/FSV to its default settings by pressing the PRESET key.
The R&S FSVA/FSV is in its default state.
2. Set center frequency to 1 GHz and the frequency span to 3 MHz.
3. Set the reference level to -10 dBm and RF attenuation to 0 dB.
4. Set the resolution bandwidth to 10 kHz.
The noise is reduced, the trace is smoothed further and the intermodulation prod-
ucts can be clearly seen.
5. Set the VBW to "1 kHz".
Measuring intermodulation using the 3
rd
order intercept (TOI)measurement func-
tion
1. Press the MEAS key and then the "TOI" softkey.
The R&S FSVA/FSV activates four markers to measure the intermodulation dis-
tance. Two markers are positioned on the useful signals and two on the intermodu-
lation products. The 3
rd
order intercept is calculated from the level difference
between the useful signals and the intermodulation products. It is then displayed
on the screen:
