Rx Noise Level - Kongsberg EM 712 Maintenance Manual

Kongsberg EM 712 Maintenance Manual

RX noise level

Checks the isotropic spectral noise level.
This test measures the average isotropic spectral noise level for each receiver channel
(in dB rel 1 μPa/Hz) for different frequency bands. The receiver directivity index, the
transducer sensitivity and the filter bandwidth is used to convert to isotropic spectral
noise level.
Dark green modules are to be tested. Light green modules have to function to be able
to perform current test.
