PT5 - Electronics Wrap Around

The PT5 test is not a valid test and will be removed in a future firmware release.
This test sets up the H-ADCP in a test configuration in which the test output lines from the DSP Board
timing generator are routed directly to the Receiver board. The receiver then processes this signal. The
test output signal sends a certain correlation pattern when processed. The ideal pattern is as follows.
0 0 0 0

Acceptable deviations from this pattern are due to deviations in sampling bandwidth and demodulator
low-pass filter bandwidth variations. For example:
