Totalizer Commands

[SENSe:]
TOTalize:SLOPe {NEGativePOSitive}[,(@<x		>)]
TOTalize:SLOPe? [(@<x	>)]

Configure the totalizer to count on the rising edge (default; positive) or falling edge (negative) of the input signal. The totalizer channel is numbered “ 03”, where represents the slot number. The :SLOP? query returns the edge selection. Returns “NEG” or “POS”.

[SENSe:]TOTalize:CLEar:IMMediate [(@<x		>)]
Immediately clear the count on the specified totalizer channels.
The totalizer channel is numbered “	03”, where is the slot number.
[SENSe:]TOTalize:DATA? [(@<x	>)]
Read the count on the specified totalizer channels. If you have selected
the RRESet parameter in the TOT:TYPE command, then the TOT:DATA?
command will reset the count to “0” after it is read. The count is reset
regardless of whether the specified channels are in the scan list or even

whether a scan is in progress. The maximum count is 67,108,863 (226-1).
The count rolls over to “0” after reaching the maximum allowed value.
The output from this command is affected by the FORMat:READing			5
commands (see “Reading Format Commands” on page 231).
