Example 1: RF Power Measurements with a Power Sensor
Measurement
The FSMR includes a power meter functionality. Measurements of RF Power will be performed in the
power meter mode with highest accuracy. The FSMR will automatically handle all required correction
factors and compensate the measurements. The FSMR does support the following Rohde&Schwarz
power sensors:
o
R&S NRP-Z11 10 MHz to 8 GHz / 200 pW to 200 mW
o
R&S NRP-Z21 10 MHz to 18 GHz / 200 pW to 200 mW
o
R&S NRP-Z51 DC to 18 GHz / 1 uW to 100 mW
o
R&S NRP-Z55 DC to 40 GHz / 1 uW to 100 mW
Main Receiver Functions
The power meter functions are available in the Measuring Receiver POWER METER -mode. All required
settings and evaluations can be reached from the POWER METER main menu.
Measurement Setup
Fig.2-2 RF Power measurement setup
The following settings are used on the generator:
1. PRESET the generator.
2. Set RF Frequency to 1 GHz.
3. Set the output level to 0 dBm.
Measurement Sequence – RF Power Measurements
Connect the Power sensor with the Signal Generator output and with the Measuring Receiver power
sensor connector on the front panel.
The following steps are performed:
1. Zero the power sensor.
2. Connect the power sensor to the DUT.
3. Set the RF frequency.
4. Measure the RF Power
