Product Highlights
Option 238 adds time gating capability to the FieldFox spectrum analyzer. 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. 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.

Span range: any span
RBW range: 1 Hz to 300 kHz (derived from gate width)
