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 ...

Radar waveforms are classified into three categories based on the bandwidth of operation. With multiple waveforms available for use, such as FMCW and pulse-modulated, it’s imperative to decide on the ...
