PC-based USB spectrum analyzers for basic test and measurement routines introduced by Saelig
FAIRPORT, N.Y., 17 Oct. 2014. Saelig Company Inc. in Fairport, N.Y., is introducing TSA range of spectrum analyzers, which are USB-stick-sized miniature RF tools that are PC-connected devices able to perform many basic test & measurement routines.
The TSA analyzers cover a wide measurement range in three models. The TSA4G1 covers 1 MHz to 4.15 GHz; the TSA6G1 covers 1 MHz to 6.15 GHz; and the TSA8G1 covers 1 MHz to 8.15 GHz.
They accept signal levels into standard SMA input connectors from - 110 dBm to +30 dBm (input power up to 1 Watt) 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 remote feature helps users control the PC-connected USB-powered analyzers remotely from anywhere via the Internet. Frequency stability is +/- 5ppm and the minimum scanning step is 2 kHz at 1 MHz span. Resolution bandwidths can be set to 50 kHz, 100 kHz, 200 kHz, or 500 kHz. Scanning over the whole frequency range is 0.2 seconds for fast-scan, and 2.3 seconds for normal scan.
Signal processing is performed with the free downloadable PC-based software. Once the device's parameters are set (center frequency and span, markers - peak, minimum or arbitrary, max hold, amplitude and reference level, sweep time and number of screen captures), the analyzer immediately commences a frequency sweep on pressing the "Start" button. The resolution bandwidth is automatically selected based on the span.

No larger than a pack of chewing gum, the TSA analyzers are or rapid EMC analysis and for troubleshooting RF signals in wireless remotes, cordless phones, wireless monitors, ATE systems and radios, Bluetooth, WiFi, WiMax and other wireless applications, for field service, installation, and education.
Accurate and stable in frequency, they can be used for EMC pre-compliance testing with the optional inexpensive near-field probe set TNP6Gx. This probe set includes two magnetic (H) field and two electric field probes, designed for resolving emissions problems.
