An optional high-precision 50 MHz/1 GHz reference source module (R&S NRX-B1 sensor check source - hardware option) can be used in CW mode to check the function of all R&S NRP power sensors. In pulse mode, the test generator can be used to check the pulse measurement performance of the R&S NRP-Z8x wideband power sensors or the R&S NRQ frequency selective power sensor.

Note: Product image demonstrates the NRX power meter's modular concept which allows users to choose between the R&S NRX-B9 or the R&S NRX-B1 option.
