EMI measurement capability for spectrum analysers

Supplier News

AGILENT Technologies has added three detectors to its PSA series of spectrum analysers for performing electromagnetic interference (EMI) precompliance measurements on devices.

The peak, average and quasipeak 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 analysers. The speed and sensitivity of the PSA with EMI measurement capability makes it suitable for troubleshooting in electromagnetic-compatibility (EMC) test houses and companies that have dedicated precompliance and in-chamber testing.

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

The EMI measurement capability adds another tool to the PSA. The PSA also offers phase noise, noise figure, flexible modulation, 11 standards-based measurement personalities and 80MHz wide information bandwidth measurements.

Multiple connectivity interfaces speed system integration including IVI-COM and VXI plug and 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.
