PT7 RSSI Bandwidth Test 

 

Criteria for failure

. Any one of the following conditions will flag failure for the beam: 

•

 

Nominal noise floor <20 or >60 

•

 

Counts for ms 1 through 4 not rising 

•

 

9th ms sample not between 70 and 100% of nominal counts 

To verify a RSSI failure, re-run the PT7 test in a different location and change the orientation 180 degrees 

to determine if any external interference is an issue: Even try running PT7 at a different time of day to 

eliminate powerful radio transmitters. 

 

The ADCP should be in non-moving water during this test to get valid test results.
