NRP-Z Power Viewer
The R&S
SMJ features the power viewer function for measuring or monitoring either
the RF output power, or a freely selectable signal source with R&S NRP-Z power sen-
sors.
The instrument can perform up to 4 power measurements simultaneously.
To connect the sensors you have the following options:
●
connect the sensor directly at the SENSOR connector.
A sensor connected there is always assigned as "Sensor 1".
●
connect the sensor directly at a USB connector
To connect a sensor directly via USB, use one of the appropriate adapter cables
R&S NRP-Z3 or R&S NRP-Z4.
●
connect the sensor indirectly via USB using the R&S NRP-Z5 USB Sensor Hub.
For the assignment to the available connectors, see
Chapter 2, "Preparing for Use"
Using the R&S NRP-Z5 Sensor Hub
The R&S NRP-Z5 USB Sensor Hub (high-speed USB 2.0) can host up to 4 R&S NRP-
Z sensors and provides simultaneous internal and external triggering of all connected
sensors. You can directly connect the R&S NRP-Z Sensors to the standard NRP sen-
sor connectors of the hub.
The hub is connected to the R&S
SMJ either with the R&S NRP-Z2 extension cable, or
via USB with the adapter cable R&S NRP-Z4.
See also the R&S website
Voltmeters > R&S NRP-Z Sensors" for information on the sensor hub and the available
accessories.
The instrument automatically detects a connected R&S NRP-Z power sensor and indi-
cates it in the "NRP-Z Power Viewer" dialog. Each connected sensor is assigned to
one of the four channels, according to the sequence of connection.
For device specific information on the connected sensor see the
on page 136 dialog. For information on the scope of your power
sensor refer to the manual of your R&S NRP-Zxx power sensor.
A sensor continuously measures the average signal power of the selected source,
such as an external signal, or the output signal of the signal generator with the RF level
used as reference value. The signal generator shows the result in the
settings dialog, but you can also permanently display the readings in
the block diagram.
