What is “Real Time” Analysis?

Understanding Real Time Analyzers and Real Time Analysis

General Definition of Real Time

• Measurement operations where all signal samples are used in calculating

measurement results of some kind (usually spectrum)

Real Time Bandwidth (RTBW)

• The widest analysis bandwidth where an analyzer can maintain real time

operation

• Duration of maintaining real time operation is not specified; it may

assumed to be short term or long term or unlimited

Current Usage for Signal Analyzers

• A spectrum or FFT analyzer having a signal processing path where most or

all samples, even at wide bandwidths, are used to create a spectral display

or to trigger signal measurement or acquisition (sometimes both)
