The Tektronix RSA3300A and WCA200A series real-time spectrum analyzers (RTSA) capture continuous time records of time-varying RF signals, providing time-correlated analysis in the frequency, time, code, and modulation domains. You get vector signal analysis, wideband spectrum analysis, and RTSA trigger-capture-analyze functionality in one portable instrument.
This document provides an overview of the real‑time spectrum analyzer series, highlighting the unique trigger‑capture‑analysis workflow, multi‑domain analysis capabilities, and supported RF standards such as 3G, W‑CDMA, GSM/EDGE, and radar. It also details the optional accessories and software upgrades that extend functionality.
Detailed sections cover trigger modes, capture bandwidth, analysis functions, measurement speed, frequency accuracy, noise performance, hardware specifications, safety compliance, and installation options. The manual includes ordering information, accessories list, and service options for the RSA3303A, RSA3308A, WCA230A and WCA280A models. This manual is written in Chinese.
