The R&S SMA 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 sensors.
The instrument can perform up to 4 power measurements simultaneously.
- 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 "Preparing for Use".
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 "NRP-Z Power Viewer Settings" settings dialog, but you can also permanently display the readings in the block diagram.
