Programming The Type C Function Card 4-18
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
DESCRIPTION:
These commands configure the 2461 TYPE C to measure
the positive or negative pulse width time of the signal on the
input channel 1.
The ARRay command programs the counter for multiple
pulse width measurements as specified by the <array size>
parameter.
The execution of these commands forces the following
settings: channel 1 and 2, which are common. The slope
selection of channel 1 is set to positive (for positive pulse
width measurement) or negative (for negative pulse width
measurement), the slope selection of channel 2 is set to
negative (for positive pulse width measurement) or positive
(for negative pulse width measurement) and auto trigger is
selected. The forced settings exist only while this function is
selected; when the instrument is set to a basic function, then
the previous values of these settings are restored.
The optional <expected value> and <resolution> parameters
are used to derive the required number of digits of resolution.
Their units are seconds. The actual resolution derived by the
2461 TYPE C is determined by both the input signal and the
resolution set.
INITIALIZATION:
*RST Resolution = 8
EXAMPLE:
"CONFigure1:PWIDth 10"
Configures the 2461 TYPE C to measure the positive pulse
width of the signal applied to channel 1 (10 measurements).
