Real-Time Spectrum Analyzers overcome the challenges associated with today’s complex RF signals with both
frequency and time domain event triggers. These advanced triggers provide the ability to capture a seamless
record of RF signals into memory and perform time-correlated, multi-domain analysis.
Unlike traditional swept spectrum analyzers, the Real-Time Spectrum Analyzer offers a Power Trigger with
user-settable span, enabling spectrum capture whenever the power of any signal crosses a user-defined
threshold. Tektronix’ exclusive Frequency Mask Trigger enables the capture of the spectrum of interest when
a discrete change in signal frequency, amplitude, or bandwidth occurs, or when a signal appears or disappears.
Frequency Mask Triggering occurs even if spectral events are detected at a much lower level than adjacent
signals. In addition, the flexibility of the Frequency Mask Trigger enables the creation of a customizable mask
that can monitor multiple different frequency bands within the analysis span.
