The Spectrum Analyzer — Radar and Satellite Communications Analysis
You need to easily compute both
magnitude and phase
Infiniium Z-Series oscilloscopes include
a Fast Fourier Transform (FFT) for
frequency domain (spectrum) analysis. The
integrated FFT offers an alternative to a
dedicated spectrum analyzer. Use the FFT
to compute both magnitude and phase
and take advantage of several useful
features to assist in spectral analysis.
The FFT can control span and resolution
bandwidth. Automatic measurements
and markers measure spectral peak
frequencies and magnitudes as well as
deltas between peaks. Use the amplitude
demodulation (envelope mode) to measure
The Z-Series FFT quickly identifies peaks and has key controls such as span, start and stop, which
make the oscilloscope behave more like a spectrum analyzer.
rise and fall times on the entire envelope.
Z-Series features the following
to enable extreme RealEdge
analysis
– Multiple FFT windows including
Hanning, rectangular, Blackman-
Harris, flattop, and Hamming
– Peak search and navigation for fast
analysis
– Amplitude modulation (envelope
mode) — create radar envelopes
– FFT mask trigger
– Gated FFT measurements
Ampltitude demodulation makes it possible to analyze difficult waveforms such as envelopes.
Use the FFT mask to test frequency margins and capture rare events.
