Performing and Configuring Measurements
After you have connected a power sensor, the R&S Spectrum Rider immediately starts
to measure the signal power.
When measuring high powers, pay strict attention to the following instructions to avoid
personal injury and to prevent the power sensor from being destroyed
Risk of skin burns and / or damage to the R&S Spectrum Rider
Measuring high powers may lead to skin burns and / or damage to the R&S Spectrum
Rider. You can avoid it by:
●
Never exceeding the permissible continuous power. The permissible continuous
power is indicated on a diagram on the back of the power sensor.
●
Turning off the RF power when connecting the power sensor.
●
Connecting the RF connectors tightly.
Defining the center frequency
To get the most accurate results, you should synchronize the frequency to that of the
signal.
Note that the R&S Spectrum Rider maintains the center frequency that you have set in
another operating mode. In that case, it uses that frequency as the power sensor fre-
quency.
If you want to perform measurements on another known signal, you can change the
power sensor frequency manually.
1. Select the "Freq" softkey.
The R&S Spectrum Rider opens an input field to define the frequency opens.
2. Enter the frequency of the signal.
The R&S Spectrum Rider transfers the new frequency to the power sensor which
then corrects the measured power readings.
Zeroing the power sensor

Setting the power measurement weighting mode
For forward power display, the R&S Spectrum Rider provides both average power and
peak envelope power.
1. Press the [MEAS] key.
2. Select the "Fwrd Pwr Display" softkey.
3. Select the weighting mode you require.
