Tektronix RSA3408B

The Tektronix RSA3408B is a used real time spectrum analyzer that remains popular among RF engineers who need to capture and analyze transient and complex modulated signals. This instrument provides real time signal analysis bandwidth that allows users to detect infrequent or short duration events that traditional swept analyzers can miss. It has been previously owned and shows normal signs of use consistent with a well maintained lab instrument. Engineers use this analyzer for spectrum monitoring, interference hunting, and detailed characterization of digital modulation schemes found in wireless communication systems. The RSA3408B includes frequency mask triggering and time correlated multi domain analysis that helps troubleshoot elusive RF problems. Its combination of speed and depth of analysis has kept it relevant in many labs even as newer models have been introduced. This unit is a strong fit for research facilities, defense contractors, and communications companies that require dependable real time spectrum analysis on a budget. It supports development and validation work across radar, telemetry, and wireless infrastructure projects. The analyzer has been functionally checked before listing to ensure it meets expected performance standards.
