Dear NI Support,

I have a question regarding acquiring samples of HP 34970A.

I have necessity to acquire samples each 4 seconds (the instrument can acquire samples up to 50,000) but, during the weekend, I don't have possibility to check the instrument and, then, make downloading the samples; what will happen if the DMM gets full? Are the samples overwritten? Is the acquisition stopped?

I am looking forward to hearing from you as soon as possible.

Best regards,

Stefano Petrini

Hello Stefano,
     If you are not already, I recommend that you download and use the LabVIEW Instrument Driver for your instrument.  With the driver, you can programmtically read the values from the instrument and then store them on your PC.  I recommend storing the values in an array and then writing them to a file every 30 minutes.  The example VIs that come with the driver should give you a good starting point.  As an additional bonus, you could have the application send you an email with the data, but that might be a little too complicated to implement and properly test today before you leave for the weekend.

Let us know how it goes,

NathanT

Hello Nathan,

many thanks for your quick support.

Unfortunately the instrument is configured with HP Benchlink software and the samples are acquired directly from the instrument and saved into the internal memory.

After then, the samples will be dowloaded on the PC and saved into log file; I don't have any possibility to use LabView now.

At the moment I have need to know what happen when the internal memory of instrument is fully (when the number of samples acquired exceed the max value).

I am looking forward to hearing from you as soon as possible.

Best regards,

Stefano

If you are not using any NI software or hardware, not sure why you are posting a question to NI's forums about Agilent hardware and software.

The answer to your question about the scanning and what happens when the 50,000 readings limit is reached can be found in the manual for the instrument. Old readings are overwritten.
