StreamPro ADCP Operation ManualPT3 - Receive PathThis test displays receive path characteristics. This test has three parts.• Part 1 - The ADCP pings without transmitting and displays theresult of an autocorrelation function performed over eight lag periods.Ideally, we should see high correlation at near-zero lags,and then see decorrelation as the lags get longer. High correlationvalues at longer lags indicate interference is present.• Part 2 - The ADCP displays the hard limited duty cycle (shouldbe near 50%).• Part 3 - The ADCP displays the RSSI value.>pt3Mag (%)Lag Bm1 Bm2 Bm3 Bm40 100 100 100 1001 97 96 97 972 88 86 88 883 77 72 77 774 66 59 67 685 61 50 60 636 58 46 57 607 58 44 56 59Sin Duty(%) 33 42 39 41Cos Duty(%) 21 19 18 16RSSI (counts) 65 60 69 65page 52Teledyne RD Instruments
