10.4.13 Single Phase Data Capture Sequence
For a single phase data capture, only the data from channel 1 will be recorded, so the data
capture will only trigger on channel 1. 100 waveforms are captured with each filter for a total
of 300 waveforms.
The single-phase capture sequence is shown in Table 2.
Stage Filter Data Type Trigger Channel
1 Unfiltered Raw 1
2 Unfiltered Waveforms 1
3 Filter 1 Raw 1
4 Filter 1 Waveforms 1
5 Filter 2 Raw 1
6 Filter 2 Waveforms 1

10.4.14 Three Phase Data Capture Sequence
For the three-phase data capture, events for all phases will be captured, and then for each
filter a waveform capture will be done triggering from each of the channels. This is shown in
Table 3.
Sets of 100 waveforms are captured with each filter, for each trigger channel. As the unit is
in three-phase mode, each set of waveforms will contain a waveform from each channel.
This gives a total of 2,700 waveforms or 900 waveforms per channel.
As there are more data capture stages, for cables with the same levels of activity the three-
phase data capture will take longer than for single-phase captures.
