The Tektronix 3066 Real-Time Spectrum Analyzer operates from DC to 3 GHz and captures frequency spectra in real time across spans up to 5 MHz for RF/Baseband input. Unlike traditional sweeping analyzers, it acquires blocks of frequencies simultaneously, eliminating the risk of missing transient events and burst signals. The instrument analyzes signals across frequency, time, and modulation domains with post-capture zoom capability up to 1000:1. Symbol rate analysis reaches 5.3 Msymbols/sec, supporting W-CDMA signals with chip rates to 16.384 Mcps.
