Statistics
If your Counter contains other than the current firmware revisions,
single-shot statistics are not available using the ON SINGLE: menu item
found in the Statistics menu (use Stats key).
HP-IB Commands
[:SENSe]:EVENt[1|2}:HYSTeresis:RELative
If your Counter contains firmware revisions 3402 and below, the input
hysteresis command and query does not operate in the conventional way.
That is, [:SENSe]:EVENt[1|2]:HYSTeresis:RELative sets high sensitivity
when the parameter is MINimum or 0 percent, and sets low sensitivity
when the parameter is MAXimum or 100 percent.
In the prior firmware revisions (3317, 3335, or 3402), MINimum or
0 percent corresponded to low sensitivity, and MAXimum or 100 percent
corresponded to high sensitivity.
:CONFigure:TOTalize:TIMed
:CONFigure:TOTalize:CONTinuous
:MEASure:TOTalize:TIMed?
If your Counter contains firmware revisions 3402 and below, the Totalize
Measurement Instruction commands (shown above) are not available to
disable auto-trigger.
In the firmware revisions 3402 and below, these commands enabled
auto-trigger at the 50% level.
