Adjust the range switch of the PMx so that the maximum RF output power of the
frequency converter is within the selected power range. See the data sheet of the
related converter type and the suitable PMx manual for details.
●
To increase calibration accuracy, zeroing the PMx power meter is recommended
before calibration step 1 (reference receiver calibration). Zeroing is particularly
important if low measurement ranges are required. After mounting the sensor head
to the frequency converter, allow sufficient thermal settling time (1 hour is recom-
mended). After the system has reached thermal equilibrium, switch off the conver-
ter’s RF output power by selecting Channel – [Pwr Bw Avg] > "Power" > "RF Off All
Chanels" on the VNA. Press the [ZERO] button on the front panel of the PMx. After
that, reactivate the converter’s output power by deselecting "RF Off All Chanels".
Other power meters supported by the VNA
In general, the Leveling Tool can work together with any power meter that is supported
by the analyzer firmware. Setup, configuration and operation are similar for all power
meters, however some advanced communication features are limited to R&S
NRP
power sensors. For information see
