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.
