A small footprint and an easy user interface are augmented by a high-performance specification with many advanced measurement functions and capabilities, and the base units already provide comprehensive measurement coverage. A spectrum analyzer measures signal amplitude across a range of frequencies, letting an engineer characterize spectral content, noise, and distortion in the frequency domain. The T3SA3000 series is suited to the research laboratory, the development laboratory, repair and maintenance, the calibration laboratory, automatic production test, and general bench-top use. ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. ## Brand Heritage Teledyne Test Tools is a brand of Teledyne LeCroy, a test and measurement manufacturer founded in 1964. LeCroy Corporation became part of Teledyne Technologies in 2012, and the business has operated as Teledyne LeCroy since then. ## Compare Other Models in This Series The Teledyne Test Tools T3SA3000 range is built around a common platform, with models distinguished primarily by upper frequency limit — 9 kHz to 2.1 GHz on the T3SA3100 and 9 kHz to 3.2 GHz on the T3SA3200. Both share the same small footprint, 10.1 inch display, all-digital IF architecture, and advanced measurement function set. Across the family the base instrument provides comprehensive spectrum analysis, and each model accepts the same set of option kits — Tracking Generator, EMI Pre-compliance, Reflection Measurement, and Advanced Measurement — so the choice between models centers on the frequency coverage an application requires. Each model in the family is listed as its own dedicated product page with condition-matched pricing. Select the new T3SA3100 or new T3SA3200 page that matches the frequency coverage you need; the specifications and option compatibility described here apply to every unit in the series. The principal difference between the two models is upper frequency limit: the T3SA3100 covers 9 kHz to 2.1 GHz while the T3SA3200 covers 9 kHz to 3.2 GHz, with the maximum frequency span tracking each model's range. The optional Tracking Generator likewise spans 100 kHz to 2.1 GHz or 100 kHz to 3.2 GHz to match the host analyzer. Core performance specifications are common to both models, including the -161 dBm/Hz typical Displayed Average Noise Level, -98 dBc/Hz typical phase noise, total amplitude accuracy under 0.7 dB, and 1 Hz minimum resolution bandwidth.
