Rohde & Schwarz R&S®Spectrum RiderFPH Handheld Spectrum Analyzer 9
Optional software applications
Power measurements with power sensors
For applications requiring very high accuracy to measure
and align transmitter levels, the R&S®FPHK9 option allows
the R&S®Spectrum RiderFPH to be used for power mea-
surements together with the R&S®NRP power sensor se-
ries, with a measurement range of –70dBm to +45dBm
and covering frequencies up to 110GHz.
When used with an R&S®HAZ360/Z361 optical power
sensor, the R&S®Spectrum RiderFPH power meter mode
reads out optical absolute power in dBm as well as relative
power in dB.
Internal channel power meter
The R&S®FPHK19 channel power meter option converts
the R&S®Spectrum RiderFPH into a portable power me-
ter with a level measurement accuracy of typ. 0.5dB. This
option makes it possible to achieve power measurement
results fast and easily without needing a power sensor or
the spectrum analyzer mode. This can help in applications
such as checking power levels throughout the signal path
of a field transmitter or verifying the power level of a de-
vice under test (DUT) in the lab.
Pulse measurements with power sensors
The R&S®FPHK29 option enables precise pulse and peak
power measurements using the R&S®Spectrum RiderFPH
together with the R&S®NRPZ8x wideband power sensor
family. The R&S®NRPZ8x wideband power sensors mea-
sure pulses with a resolution of up to 50ns and support
frequencies up to 44GHz.
The main pulse parameters such as pulse width, rise/fall
time and duty cycle will be displayed automatically. It is
also possible to use the trigger function and markers and
to zoom in on pulses by reducing the trace time. This is
convenient for installation and maintenance measure-
ments of radar systems.
