Totalize X-Y During a Preset Time

This is a count/totalize function during a predefined time. The start/stop signal is generated by the counter and set by <time for gate open>.

The counter counts up for each event on the X-channel and down for each event on the Y-channel. The result is the difference between the two channels.

If you only want to Totalize on X, you must disable Y by setting both X and Y to the same channel or disconnecting the signal from Y.

Totalize –Y MANUAL, negative totalizing, is possible if you physically disconnect the signal on the X input.

Select if the counter should count positive or negative transitions with the IN- Put:SLOPe command of the channels.

Parameters:

<time for gate open> is the time you want the totalizing to proceed. The range is the same as for Measurement Time.

The first <(@«124»)> is the channel that counts up, and the second one is the channel that counts down:

(@1) means input A

(@2) means input B

(@4) means input E (rear panel arming input)

If you omit the channels, the instrument counts up on input A and down on input B.

Example:

SEND￿ :MEAS:TOT:TIM? ￿ 1,(@1),(@1)

In this example the counter totalises the pulses on Channel 1 for one second. Any signals on channel 2 and 4 are ignored.

*RST condition:

Time for gate open = 10 ms ([:SENSe]:ACQuisition:APERture)
