LAPLACE PRE-SELECTORS FOR CONDUCTIVE EMC TEST

LAPLACE INSTRUMENTS RF910 AND RF915 EMC PRE-SELECTORS

Laplace Instruments RF915 Pre-SelectorPre-

  • Selectors are an essential requirement if measuring conducted emissions that have high broadband noise content. They effectively convert an EMC Analyzer into a receiver, as specified by CISPR16.

    The Laplace Pre-Selectors are high specification, switched band filters which track the scanning of the EMC Analyzer. Control is via a USB cable from the Laplace EMC Engineer software supplied with the SA1002 and SA3000 emission analyses.

    The Installation and operation of the pre-selectors are completely automatic, and the filters will automatically synchronize with the emission analyzer and will scan without any operator intervention. A front panel switch allows manual operation if required.

    Two pre-selector models are available:
    1. RF910 Band B, 150KHz – 30MHz. 8 filter bands
    2. RF915 Band A & B, 9KHz – 30MHz. 13 filter bands

    Pass band attenuation is just 4dB and out-of-band rejection is nominally 40dB.

    Key Points
    · Fully automatic operation.
    · Band A (RF910)and band A+B (RF915) versions.
    · No active components in RF path, so very high noise tolerance.
    · 5 + 5 pole filters for high out-of-band rejection.
    · Can be used with any EMC analyzer.
    · Compact and cost effective.

    Pre-Selectors for EMC test is an optional extra for the following products:
    – SA3000 3GHz EMC emissions Analyzer
    – SA1002 1GHz EMC emissions Analyzer
    – RF300 Large Loop Antenna
