Hello MVK,
The NI PXI-5660 RF Vector Signal Analyzer can use virtual
instrumentation to many different types of measuremenrts, even those
that may not be shipped as native features since they can be built from
components that are currently available. Such is the case for CNR
measurements. I am attaching an example written for another RF customer
looking for CNR measurements, which is built upon the native power in
band and spectrum peak search measurement routines. A power in band
measurement is used to measure the noise power of the signal, and a
peak search measurement is used to measure the peak power of the CW
tone.
