We take this frequency domain spectrum and turn it back into a time domain signal. We measure the 10-90 rise time of ... We can measure the 10-90 rise time off the graph. When we compare the ...

On some performance oscilloscopes, you can actually set the center frequency, span, and resolution bandwidth you desire in the “spectral analysis” math function. The scope will then gate your ...

Turns out, adding in the frequency domain looks like multiplication in the time domain ... doesn’t tell you much, but the graph shows how the signals mix together quite nicely.

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users ...

The analysis of RF and microwave signals in the frequency domain ... use of the FFT to efficiently convert sampled time-domain data into a frequency-spectrum display. The FFT can output spectral ...
