1. Press the [FREQ/DIST] key.
The R&S
ZNH opens an input field to set the center frequency.
2. Enter the required frequency.
Define the power
It is important not to overload at the RF input. Supply a suitable signal source and
attenuate the receiving power depending on the DUT characteristics.
1. Press [SCALE/AMPT] key.
2. Select "TG Power" to set the output signal source.
The R&S
ZNH opens an input field to set the tracking generator power.
3. Set the required power level.
4. Select "Receiver Att" to attenuate the receiving power at the RF input.
The R&S
ZNH opens an input field to attenuate the receiving power at the RF input
of R&S
ZNH .
5. Set the required attenuation level.

Analyzing Measurement Results
If you perform measurements on different DUTs whose results you would like to com-
pare, you can save the current results as reference values.
1. Press the [MEAS] key
2. Press the "> Ref" softkey.
The R&S
ZNH saves the results as the reference result for future measurements.
The magnitude and phase results displayed show the difference of the current
measurement and the reference measurement. The unit for reference measure-
ment is always dB. For more information, see
