harmonicANHarmonics Measurements Scorpion Application Note Swept Vector Harmonic Measurements Using a VNMS Introduction Harmonic measurements have long been used to characterize a device-under-test’s (DUT) non-linearity and have traditionally been measured with a synthesizer and a spectrum analyzer. A potentially faster, more integrated, and more exible solution is to measure the DUT’s harmonics on a Vector Network Measurement System (VNMS). This application is intended to enable the measurement of a device’s harmonics on a MS462xx over a possibly large dynamic range (up to 60 dB or more in some cases) with a number of measurement options. There are two modes of operation to allow maximum exibility: a CW mode (for a display similar to that of a spectrum analyzer) and a swept mode where both the ……
