How can I recieve Data continously from a Keithley 2000 Multimeter over GPIB?

[Sven_Kraus]

I'm using a Keithley 2000 Multimeter but I haven't got a clue how to manage this. The only thing i can do is a "one shot" measurement. Maybe someone has an Idea.

Hi,

You'll have to dig into the trigger layers. Keithley instruments have
multiple trigger layers (two or three I think).

The first is to start a measurement.
Second is to continue.

So, you'll have to configure (with GPIB or manually) the trigger layers.
This system is not easy at all, but very flexible. Keithley has examples on
there site, in several languages (not sure about LabVIEW..).

Regards,

Wiebe.

You can use your GPIB write and read "one shot" command inside a while loop updating a chart indicator.

It depends on how fast do you need consecutive measurements. First, try to use your "one shot" inside a loop and you can have an idea about the maximum speed using this method. If it's not enough, you have to store data in instrument's memory (just triggering the start and have set the maximum measurement rate) ... anyway, the amount of data aquired continuously is limited by available memory.
Maybe other features are available and I don't know about them. Therefore, you may check this pages to find out details.
