7.3 The Network Data Port
The network data port outputs phase difference data while the test set is in the Collecting state. The
phase differences are in units of cycles of the Input signal. Phase differences are output as floating
point numbers, one number per line, either 1, 10, 100, or 1000 samples each second. The default
rate is 1000 samples per second, to change the rate use the set phaserate command. See “Chapter
7, Setting Data Port Output Rate” on page 65.
