Can I test the control lines of a 6534 DAQ device in a C++ environment?

[Seth B]

The signals going into the control lines (REQ and PCLK) of my 6534 DAQ card are becoming quite distorted (longer rise time, decreased amplitude and ringing around 2.5-3 V). I have tried buffering them from my peripheral device without success. I am using a short 1M cable. I would like to test the integrity of these control lines. Searching your site, I could only find a testing utility for Labview. My application is written with Borland C++ using the example code for single buffer burst mode with an external PCLK provided with the card. I am attempting to operate in the burst mode with a 20 MS/s transfer rate.

Hello,

I am not sure exactly what you would like to test here. Is it that you would like to know if you external signals are valid? This is my assumption.

1.) Could you provide a link or tell us where the testing utility for LabVIEW is?
2.) Could you explain in more detail what is happening that makes you want to do these tests?

Best regards,
