Low Cost Spectrum Analyzer for Pre-Compliance-Tests

Rigol-Low-Cost Analyzer06 March2013 - RIGOL Technologies introduces new options for its best selling low cost spectrum analyzer DSA815-TG. This compact instrument is designed for multiple applications, and in combination with an additional 1.5 GHz tracking generator and an optional VSWR bridge it can also be used as a scalar network analyzer. In particular the DSA815-TG is a great tool for EMI pre compliance testing according to CISPR 16.

Spectrum analysis is a necessary task in many test laboratories, but one that usually comes with a premium price tag. The DSA815-TG spectrum analyzer from RIGOL Technologies represents a cost-effective alternative for engineers in need of this measurement capability but with limited funds. This full-featured instrument incorporates an all-digital intermediate-frequency (IF) section for accurate, high-resolution measurements from 9 kHz to 1.5 GHz and significantly reduces amplitude deviations over time and frequency compared to analog technologies.

With additional options like the EMI Filter & Quasi Peak Detector and the Advanced Measurement Kit the spectrum analyzer DSA815-TG is ideal for pre compliance tests of boards, devices and components. This allows customers to troubleshoot and test designs on their bench without having to schedule and pay for time at a full compliance lab. The pre testing helps engineers to stay within the EU-wide regulations for EMC already during the design phase and prevents from very expensive re-designs. It results in reduced development time and accelerated time-to-market.

Although the DSA815-TG does not perform exactly like a fully compliant EMC test instrument according to CISPR 16-1-1, it is ideal for all necessary pre-tests. The instrument, which stands for an excellent price-performance ratio, has already proven its advantages as a spectrum analyzer in countless applications.
