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)
