We are using an Agilent 34970A to measure an advanced scan of DC voltage points. We need to take a scan of about 1000 data points of DC voltage values (which are stored in the instrument) along with the time for each voltage value. I am using instrument drivers for the Agilent 34970A developed by National Instruments. I have attached my VI for the program. When we run the program and indicate that we do not want to include the time, the program runs in a second. When we run the program and include the time, the program takes about 30 seconds to execute, which is far too long. We can not figure out why this execution delay occurs. The Agilent company assures me that the instrument does not take this long to record voltage and time, as it does so simultaneously. According to them, it should be just as fast to read values of both voltage and time as it is for voltage values alone. We can not figure out where/if there is an error in the drivers that is causing this long time execution response. We appreciate any help in resolving this time issue.
Thank you.
