CMG-DCM Data Communications Module
The table to the right shows the current setting of the digitizer.
For example:
In this example, under normal conditions,
•
the Z and N data streams will be output by Tap 1 at a rate of
2000/10/4 = 50 Hz, and
•
the E data stream will not be output.
Additionally, when the trigger criteria are met,
•
the N data stream will be output by Taps 0, 2 and 3 at rates of
2000/10 = 200 Hz, 2000/10/4/2 = 25 Hz and 2000/10/4/2/5 = 5
Hz, and
•
the E data stream will be output by Taps 1 and 3 at rates of
2000/10/4 = 50 Hz and 2000/10/4/2/5 = 5 Hz.
The next section allows you to alter the criteria that the digitizer uses
when deciding whether a trigger event has occurred.
