This application sheet describes the use of the R&S NRQ6 frequency selective RF
power sensor as an I/Q data source for the software R&S VSE Vector Signal Explorer.
This application sheet describes a way to use the import capabilities of the R&S VSE
software to process I/Q data captured by an R&S NRQ6. For the data exchange,
*.iq.tar files are created from the I/Q data acquired by the R&S NRQ6.
2 Possible Solution
If the R&S NRQ6 is equipped with the appropriate software option, it can directly output the acquired I/Q data. You specify the radio frequency (RF), the resolution bandwidth or the sample-rate and the desired number of I/Q value pairs. The R&S NRQ6
can acquire from one up to 5 million I/Q samples at 120 Mega-samples per second.
Chapter 3, "How to Configure the R&S NRQ6", on page 2 shows a typical setup.
3 How to Configure the R&S NRQ6
Prerequisites
To use the I/Q output capabilities of the R&S NRQ6 sensor, the device must be equipped with the R&S NRQ6-K1 option. You can purchase this add-on at any time as a
supplementary option. If necessary, contact the R&S Product Marketing.
Given that the R&S NRQ6 sensor is equipped with the R&S NRQ6-K1 option, two typical configurations can be considered:
Configuration by specifying filter-bandwidth
::
*RST
::
SENS:FUNC “XTIM:VOLT:IQ” # Select IQ mode
SENS:BAND:TYPE RES # Defines that the configuration shall be
# made by specifying the resolution bw
# (That command is redundant here, because
# this setting is default after *RST)
SENS:BAND:RES:TYPE:AUTO OFF # Configuring resolution bandwidth filter
SENS:BAND:RES:TYPE FLAT # Manual selection, for example
SENS:BAND:RES 40.0e6 # 40 MHz FLAT RBW filter
SENS:TRAC:IQ:RLEN 600000 # Requesting 600000 I/Q value pairs for the
# result. This corresponds to an acquisition
# time of 10 ms, because @ 40 MHz filter band-
