Agilent Adds EMI Measurement Feature on PSA Spectrum Analyzers

8/11/2004 - Agilent Technologies Inc. (NYSE: A) announced the addition of three detectors to its PSA Series high-performance spectrum analyzers for performing electromagnetic interference (EMI) precompliance measurements on devices. The peak, average and quasi-peak detectors and bandwidths are now standard on all PSA models and are compliant with the International Special Committee on Radio Perturbations (CISPR)(1). The PSA series also offers compliant MIL-STD bandwidths and detector.

With the EMI capability, R&D engineers can easily evaluate the conducted and radiated emissions performance of their designs during the development stage using high-performance spectrum analyzers. For electromagnetic-compatibility (EMC) test houses and companies that have dedicated precompliance and in-chamber testing, the PSA with EMI measurement capability is ideal for troubleshooting because of its speed and sensitivity.

The PSA provides the CISPR 16 required, 6-dB resolution bandwidths of 200 Hz, 9 kHz, and 120 kHz, and 1 MHz impulse bandwidth filters. Additionally, the PSA provides the MIL-STD 461-required decade impulse bandwidth filters from 10 Hz to 1 MHz. The PSA displays up to three detected traces on the screen, providing faster measurements. All detected EMI peak, average, and quasi-peak signals of interest appear in a single display.

The EMI measurement capability adds another tool to the PSA, which has the widest range of functionality in a high-performance spectrum analyzer, including phase noise, noise figure, flexible modulation, 11 standards-based measurement personalities and 80 MHz wide-information bandwidth measurements. Multiple connectivity interfaces speed system integration including IVI-COM and VXIplug&play drivers to support VEE, LabView and LabWindows; and GPIB and 10 baseT LAN for automated control and remote operation. Agilent's IntuiLink, BenchLink Web Remote and Connectivity Suite software programs also support the PSA.
