Keysight Technologies,Inc. Spectrum analyzer time gating N9914A-238

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. Gated sweep Span range: any span RBW range: 1 Hz to 300 kHz (derived from gate width) Gate delay range: -150 ms to 10 s Gate width (length) range: 6 μs to 1.8 s Gate sources External RF burst Video Gate method Gated FFT
