labview interface with hp 53132A counter

[anthony797]

Hi 

I tried to get counter data into the labview. I downloaded the example code as attached and it worked.

However, the speed to fetch the data is too slow(1-2s). If I did not connect to labview, for the 8 digits resolution, the update rate in the counter is in ms level.

Is the a way to import the counter data in to labview as fast as possible?

thanks,

Yi-Chung

Hi Yi-Chung,

For the fastest measurements, you should run your initialization functions (including configuring the meter) only once at the beginning of your code. Then, you can run your "Read Measurement" in a loop. When the loop is finished, run your close function.

Hi

Thanks for replying.

Even I only put read.vi in the loop, it still needs to take around 0.7 sec to get one measurement.

If I set the measurement time lower than 0.7 sec, it will return to zero each time I get a data point.

For example, I was measuring 100 kHz signal:

I will get 100k > 0 >100k > 0....

I see, just a little bit better. You may have to contact the manufacturer to see if that is the limit when connecting the instrument to a computer or if there are settings to make it faster.
