Modular RF/microwave test instruments are quickly becoming popular among engineers due to their flexibility and substantial measurement capability in small packages. For the M9393A modular PXIe vector signal analyzer (VSA) from Keysight Technologies, the small size also applies to its wavelengths—its new, extended frequency range to 50 GHz (and continuous frequency sweeps from 3.6 to 50.0 GHz) can handle Ka-band commercial and satellite communications (satcom) testing...
