Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...
In an earlier article, we discussed the basics of setting up a fast-Fourier transform (FFT) on an oscilloscope, and why you’d want to use an FFT to get a frequency-domain view of a time-domain signal ...
Most RF and microwave analyzers have a superheterodyne architecture that down-converts the input signal to a lower IF, generally using several IF stages at different frequencies. Digital technology ...
