Keysight N9912CU/238 - Spectrum Analyzer Time Gating Option for N9912C
The Keysight N9912CU/238 is the spectrum analyzer time gating option for the N9912C. Please note, this option requires an instrument with the spectrum analysis (SA) function.
With time gating, you can measure the spectrum of a periodic signal during a specified time interval. Pulsed-RF signals are an example of a periodic signal that can be measured with time gating. For example, you can measure the pulse during the on period, not the transition or the off period. Or you can exclude interfering signals such as a periodic transient. Time gating allows you to view spectral components that would otherwise be hidden. FieldFox’s time gating method is a Gated FFT.
