See signals and events you've been missing with conventional analysis tools. With only a single acquisition, the RSA3408A Real-Time Spectrum Analyzer (RTSA) captures a continuous time record of changing RF events and enables time-correlated analysis in the frequency, time, and modulation domains. You get the functionality of a vector signal analyzer, a wide band spectrum analyzer, plus the unique trigger-capture-analyze capability of RTSA — in one, transportable package.

Unparalleled 36 MHz bandwidth Frequency Mask Trigger (FMT) makes it easy to capture transient, low duty-cycle or other difficult to capture signals. An FMT mask is simply configured using a mouse and it can be set up for one or many frequency bands within an analysis span. FMT can monitor for signal appearance/disappearance, or change in amplitude, frequency, bandwidth, spectral shape, and more—all while the instrument user is working on another task. A Power Trigger, working in the time domain and at any Real-Time analysis span, can be armed to monitor for a user-set power threshold to be crossed during a moment in time. A power detector determines total power of all signals in a span which is compared to the user-set threshold.
