Tektronix EMC Measurement Solutions Are Affordable and Effective

The time to address Electromagnetic Compliance (EMC) is before it becomes an expanding problem. Proper attention to EMC from the design stage through pre-certification testing can reduce your product development cost and decrease your time to market.

Tektronix wants to share its EMC experience and expertise with you. For over 40 years Tektronix has been a world leader in the design and production of spectrum analyzers, oscilloscopes, logic analyzers, and a wide variety of other high-technology electronic devices. In support of these products, we have established and maintained an FCC approved, in-house EMC testing facility and evolved effective measurement systems and methodologies. The knowledge gained has had an important influence on the EMC measurement tools and solutions described in this section.

One result is the 27120 EMC Pre-/Post-Certification Measurement System. It can maximize the probability that your product will be certified the first time through the EMC testing lab, lowering the cost of delays from scheduling and re-testing your products. It can also ensure continued compliance in the months and years after certification.

By combining the economical 2712 Spectrum Analyzer with a variety of supporting devices and our versatile S26EM12 EMI Test Software, Tektronix has created a pre- and post-certification system that will help you achieve these and other goals in the years ahead.

The S26EM12 PC-based EMC software package provides a straightforward means of controlling the 27120 system and managing measurement results. The software facilitates FCC, EC, VDE, VCCI, and other EMI testing. The easy-to-use 9 kHz to 1.8 GHz 2712 Spectrum Analyzer includes many features helpful in identifying and measuring EMC signals: built-in pre-amp, frequency counter, AM/FM demodulator, true analog or 4-trace digital display, peak, quasi-peak, and average detection, and 200 Hz, 9 kHz, and 120 kHz EMI filters.

Overload capability is enhanced and ambient signal interference is minimized by the 2706 Stepping RF Preselector. Biconical and log-periodic antennas, a tripod and feedline, and a LISN (Line Impedance Stabilization Network) with transient limiter enable you to make radiated measurements from 30 MHz to 1 GHz and conducted measurements from 9 kHz to 30 MHz. Magnetic and electric near-field RF probes for EMC troubleshooting round out the system. All together, this is a complete but very economical package for addressing all of your EMI diagnostic and pre- and post-certification needs. More details on the 2712 Spectrum Analyzer are available on page 195. Components of the 27120 Measurement System are also available separately.
