USB Mini Spectrum Analyzers | In Compliance Magazine

Saelig Company, Inc. announced the availability of the TSA Range of Spectrum Analyzers – economical USB-stick-sized miniature RF tools with large instrument performance. These PC-connected devices can perform most of the basic tests of much more expensive bench-top spectrum analyzers. Though tiny, the TSA Range of Spectrum Analyzers covers a wide measurement range in three models: TSA4G1 (1MHz – 4.15GHz), TSA6G1 (1MHz – 6.15GHz), and TSA8G1 (1MHz – 8.15GHz). They accept signal levels into standard SMA input connectors from – 110 dBm to +30 dBm (input power up to 1 W) and feature a noise level as low as -110 dBm. Test data is displayed on the attached PC using the supplied software, with calibrated level, linearity and frequency.

A useful ‘remote’ feature allows the PC-connected USB-powered analyzers to be controlled remotely from anywhere via the Internet, allowing for the creation of an easy-setup remote RF monitoring system. Frequency stability is +/- 5ppm and the minimum scanning step is 2kHz at 1MHz span. Resolution bandwidths can be set to 50kHz, 100kHz, 200kHz, or 500kHz. Scanning over the whole frequency range is 0.2s for ‘fast-scan’, and 2.3s for normal scan.

Supplied complete with a 60″ USB extension cable, a software CD, and a fixed 30 dB attenuator for higher power measurements, the compact (87.5mm x 23mm x 15mm) and extremely light weight (20g) TSA Range of Spectrum Analyzers are ideal for field test and servicing requirements since they are so convenient to add to a laptop bag.

Made by Triarchy Technologies Corp., an innovative Canadian RF design house, the TSA Range of Spectrum Analyzers are available now from Saelig Company, Inc. Fairport, NY, Triarchy’s authorized US distributor. For detailed specifications, free technical assistance, or additional information, visit
