both local and remote control using IEEE 488, RS-232, USB, and Ethernet interfaces. The digital control panel uses a 3.75” diagonal graphic display, menu- assigned soft keys, a single rotary knob, and four dedicated switches to offer extensive control and status-reporting capabilities. The 600A225 offers readily available RF power for typical applica- tions such as RF susceptibility testing, antenna and component testing, watt- meter calibration, particle accelerators, plasma generation, and communications and can be used as a driver for higher power amplifi ers. Last year, Agilent Technologies intro- duced its N9038A MXE EMI Receiver (Figure 5), which is compliant with CISPR 16-1-1 2010 and MIL-STD-461F. Mark Terrien, EMC business manager for Agilent, said the instrument provides the measurement accuracy and sensitiv- ity necessary for EMC testing while delivering diagnostic spectrum analysis capability to help identify and trouble- shoot sources of interference.

testing to both limits and margins, and customer-confi gurable system setup. In addition, spectrogram, zero span, and Agilent-exclusive strip-chart capabili- ties help facilitate troubleshooting and diagnostics. The MXE features an all- digital IF stage to enhance measurement accuracy by removing errors typically introduced by analog circuit elements in the IF signal chain. Terrien added that Agilent also offers an EMI measurement application that runs on the company’s X-Series Signal Analyzers, so customers can perform precompliance testing, as his colleague Handlon explained in reference 1. “This is a cost-effective way to resolve po- tential EMI issues early in the design process to avoid costly rework or delays to market,” he concluded.

The consensus is that time-to-market is critical and that success in prompt EMC approval begins with an effec- tive precompliance test strategy that can help attain fi rst-pass success in full compliance test. Whether you are look- ing for dedicated EMC test equip- ment or for a way to use equipment you already have for EMC pre- compliance test, vendors are striv- ing to meet your needs.

Terrien said that with the MXE, Agi- lent now offers a high-quality receiver that meets the needs of EMC profes- sionals as they wrestle with issues of throughput and accuracy. Time-to-mar- ket is a key driver for both commercial and military customers, he said, adding, “EMC professionals involved with both compliance verifi cation and precompli- ance analysis/diagnosis play a key role in product delivery and can provide a signifi cant competitive advantage when they improve the throughput of their facilities. High throughput not only gets the product to market effi ciently, but also keeps operational costs low.” Agilent has incorporated a range of tools into the new receiver to help fa- cilitate measurement throughput, said Terrien, including fast-scanning capa- bility for suspect list collection, built-in
