4.6.1 Using a Power Sensor
R&S Cable Rider ZPH option
R&S ZPH-K9 (order number: 1321.0409.02) option is required to operate the R&S
Cable Rider ZPH in the power sensor mode.
For highly accurate power measurements, you can connect one of the power sensors
that are supported by the R&S Cable Rider ZPH.
For a list of R&S Cable Rider ZPH supported power sensor, refer to
You can connect the list of supported power sensors to the USB port of the R&S Cable
Rider ZPH. This connector allows you to control the power sensor and supplies it with
power. For more information, see
4.6.1.1
Measuring the Power with a Power Sensor
For more information about the characteristics of the supported power sensors, refers
to their datasheet.
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 Cable Rider ZPH. 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.
