There are several ways to evaluate the bandwidth of a signal in the time domain and frequency domain. Previously we looked at the classic relationship of rise time (t r) and bandwidth (f 3db) [Ref 1], ...

There is much confusion when it comes to discussing bandwidth and logic analyzers. Traditionally logic analyzers are thought of as a purely digital measurement tool. However, as datarates increase and ...

Amateur radio license exams typically have a question about the bandwidths taken up by various modulation types. The concept behind the question is pretty obvious — as guardians of the spectrum, ...

The RF signal analyzer is one of the most versatile tools on the RF test bench, allowing engineers to measure signals ranging from electromagnetic emissions to wireless communications. Most frequently ...

Lock-in amplifiers were invented in the 1930s [1, 2, 3] and commercialized [4] in the mid 20 th century as electrical instruments that are capable of extracting signal amplitudes and phases in ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...
