5.2.2 Performing and Configuring Measurements
After you have connected a power sensor, the R&S ZVH 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 ZVH
Measuring high powers may lead to skin burns and / or damage to the R&S ZVH. 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 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 ZVH maintains the center frequency that you have set in another
operating mode. In that case it uses that frequency as the power sensor frequency.
If you want to perform measurements on another known signal, you can change the
power sensor frequency manually.
► Press the MEAS key
► Press the "Freq" softkey.
An input field to define the frequency opens.
► Enter the frequency of the signal.
The R&S ZVH 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 ZVH provides both average power and peak
envelope power.
► Press the MEAS key.
► Press the "Fwrd Pwr Display" softkey.
