interchannel delay acquisition time

Hi,

I want to make a multiple analog voltage acquisition in continuos mode, but my signal source have too high series resistances, resulting in "ghosting" between channel (for settling time, I suppose). Now I cannot change my test circuit, so I'd like to know if is it possible to set an interchannel delay between channel (with Labwindows and DAQmx library) in order to wait until the PGIA settles its input.

I'm using DAQPad 6015 and Labwindows CVI 2012

Thanks for all!

You need to see if you can change the analogue input conversion rate:

 

DAQmxSetTimingAttribute (taskHandle, DAQmx_AIConv_Rate, channelConversionRate);

Constant:  DAQmx_AIConv_Rate
Data Type:  float64
Description:  Specifies in Hertz the rate at which to clock the analog-to-digital converter. This clock is specific to the analog input section of multiplexed devices.

 


I'm not sure if this parameter can be set with your hardware.

Hi Carlorfeo,

 

you can try to set desired delay with this function. It's available for your hardware.

 

Best Regards.
