Measuring the power
1. Press [MODE] key.
2. Select "Power Meter" softkey.
As soon as the R&S Spectrum Rider recognizes the power sensor, it displays the
type of the directional power sensor that is connected in the "Title bar" (see
). After a few seconds, it also shows the forward power and return loss
currently measured at the load.
Zeroing the power sensor
Before performing the power measurement, you should zeroing the power sensor.
After zeroing is done, the R&S Spectrum Rider displays the message "Power
sensor zero done" and again shows the power sensor softkey menu.
► Connect the R&S FSH-Z14 or R&S FSH-Z44 between the source and the
load. The R&S Spectrum Rider displays the measured forward power in dBm
and the SWR of the load. For more information on using the directional power
sensor, see "Power Meter" in the R&S Spectrum Rider user documentation.
