Risk of damaging the power sensor
Because of high input power,
●
The continuous power applied to the power sensor’s input must not exceed 400
mW (26 dBm).
●
Use an attenuator for measurements on high-power transmitters.
However, brief power peaks ≤ 10 μs up to 1 W (30 dBm) are permissible.
Test setup
Connect the power sensor cable to the USB port of R&S
ZNH. If the power sensor is
having the binder connector (i.e R&S FSH-Z1, R&S FSH-Z18), the FSH-Z101 adaptor
cable is needed.
1 = Supported power sensor (e.g R&S FSH-Z1, R&S NRP-Z11)
2 = Power sensor connector (DUT)
3 = USB binder adaptor (R&S FSH-Z101)
4 = USB port connector
Measuring the power
1. Press [MODE] key.
2. Select "Power Meter" softkey.
The R&S
ZNH switches its operating mode.
If the R&S
ZNH recognizes a power sensor, it sets up a connection via the USB inter-
face. After a few seconds, the R&S
ZNH shows the measured power.
If no power sensor has been connected or is not connected appropriately, the
R&S
ZNH shows nothing.
If there are communication problems between the R&S
ZNH and the power sensor, the
R&S
ZNH displays an error message that indicates a possible cause.
For more information on the error messages, see
