Accurate Pulsed RF S-parameter Measurement with VNAs

Show Description

Vector network analyzers are traditionally used to measure the continuous wave (CW) S-parameter performance of components. Often under these operating conditions the analyzer is functioning as a narrowband measurement instrument. It transmits a known CW frequency to the component and measures the CW frequency response. If we were to look at the response of a single CW frequency we would see a single spectral tone in the frequency domain. The analyzer has a built in source and receivers that are designed to operate together in a synchronous manner, utilizing narrowband detection, to measure the frequency response of the component. Most analyzers can be conigured to generate a frequency sweep over many frequency tones.
