FILTER_n<br />

Filter Select<br />

Syntax: FILTER_n <br />

where n is either A or B<br />

Parameters:<br />

The parameter is an integer in the range 0 to 3 inclusive. 0 corresponds<br />

to no filtering, 1 to analog filter only, 2 to digital averaging filter only,<br />

and 3 to analog and digital filters combined.<br />

Function:<br />

This command selects a filter combination to be used to condition readings<br />

taken from the detector. The choices are to have no filter at all, an analog<br />

filter, digital averaging filter, and both the analog and digital filters. The<br />

digital filter processes every signal reading by averaging it with the last 9<br />

readings taken.<br />

All detectors signals are filtered to some extent even without the analog filter<br />

feature. By enabling the analog filter the signal is filtered by a 5 Hz low pass<br />

instead of the standard filter.<br />

If an attempt is made to enable the analog filter for a detector that does not<br />

support it, an execution error will occur.<br />
