ACR BER correlation to ATE for a COFDM VHF RX

Abstract

With a BER to SNR correlation, it was found that it was possible to test ACR in VHF receivers with one measurement. Moving component testing for any device from the bench to ATE poses many challenges, but releasing a high-speed RF device with a design margin issue to a production setting is somewhat challenging. To facilitate the testing of ACR in a production environment, a technique was found that correlated ACR in terms of BER to SNR. This technique, which was developed for ATE, also greatly reduced test time whilst ensuring highly reliable test results.
