It’s Darren again, filling in for Jit. Last week, we discussed FFT functionality and VSA (vector-signal-analysis) software on a scope. Sometimes I hear this called spectrum analyzer software, but in ...

The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through decimation in a spectrum analysis application. The Zoom FFT method of spectrum ...

Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...

Like a lot of hardware tinkerers, [dexter2048] has a Rigol DS1052E oscilloscope sitting on his bench. One day when trying to coax some information out of the FFT setting, [dexter] threw his hands up ...

We’ve been using Cisco’s Spectrum Expert product since its origins at Cognio, and have found it to be a very useful tool at a very reasonable price (around $4,000). For this test we evaluated the ...

The Rigol DS1000 series of oscilloscopes are popular with hobbyists for good reason: they provide decent specs at a low price. However, their spectrum analysis abilities are lacking. While these ...
