speeding up pulse width measurement c# pci 6601

[programmator]

Hi,

I try to measure the pulse width of an digital signal with a pci 6601 counter. It works fine but it ist too slow. (3 values per second). In a Measurement and Automation Studio Task a equal measurement worksy pretty fast. Could you help me to configure my counter channels for higher speeds (more values per second).

my code:

myTask.CIChannels.CreatePulseWidthChannel("Dev1/ctr0", "", 0.000001, 0.1, CIPulseWidthStartingEdge.Rising, CIPulseWidthUnits.Ticks);

CounterReader counterInReader = new CounterReader(myTask.Stream);
time = counterInReader.ReadSingleSampleDouble();

Hi programmator,

have you taken a look at the examples shipped with Measurement Studio or NI-DAQmx?

You should be able to find these files at %Documents and Settings%\All Users\documents\National Instruments\NI-DAQ\Examples\DotNET2.0\Counter\Measure Period or Pulse Width\MeasPulseWidth\cs

In this example a callback-function is used to read the acquired data asynchronously. 

Do you still observe performance issues using this example?

Best regards, 

Peter
