These Pre-Selectors are high specification, switched band filters which track the scanning of the EMC Analyser. Control is via USB link from the Laplace EMCEngineer software supplied with SA1002 and SA3000 analysers. Installation and operation is completely automatic, and the filters will synchronise with the analyser scan without any operator intervention. A front panel switch allows manual operation if required.
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 analyser.
- Compact and cost effective.
Two models are available:
RF910 Band B, 150KHz - 30MHz. 8 filter bands
RF915 Band A & B, 9KHz - 30MHz. 13 filter bands
Pass band attenuation is just 4dB and out-of-band rejection is nominally 40dB.
