(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:
"MEASure1:PWIDth? 10"
Instructs the 2461 TYPE C to measure the positive pulse
width of the signal applied to channel 1 (10 measurements).

DESCRIPTION:
These commands set the 2461 TYPE C to make single-shot
measurements of the time interval between:
(1) An event occurring at the Channel 1 input and a later
event at the channel 2 input (using separate input channels).
(2) An event occurring at the Channel 2 input and a later
event at the channel 1 input (using separate input channels).
(3) Two events occurring at the channel 1 input (using a
common input channel).
The channel specified selects the input channel for the
beginning of the interval.
The trigger slopes for the start and stop can be either
positive or negative.
The ARRay command programs the counter for multiple time
interval measurements as specified by the <array size>
