34970a

[lupiita_sopa]

hello guys... Im new in labview, now i'm working in a project, i need use the agilent 34970A for acquisition data, i need voltage, current and resistor, but i don't know how to acommodate the VIs.. i dont know in that order... and then i have to graph in real time the datos acquisition..

How fast do you want to take these measurements?  Which modules are you using in the 34970A?

In my experience with the 34980A (which is basicly a newer version of the 34970A), you will be much better off getting a cheap USB DAQ board from NI and use the DAQmx API.  There are lots of examples in LabVIEW on how to use the API.

thanks ... in this week i will try with other datalogger.. if i have a question i will be here again...

Hello lupiita_sopa,

I would like to share with you the following link where you can find information about LabVIEW instrument driver for the 34970A:

Using the Agilent 34970A with LabVIEW

Also you can find in this link six ready-to-run examples provided by National Instruments:

• EZ Scan Example: Demonstrates basic current and frequency measurements on a multiplexer module
• Advanced Scan Example. Demonstrates voltage and resistance measurements on a multiplexer module, and shows how to create a single scan list with multiple types of readings.
• Switch Example. Demonstrates switching with the 34901A and 34903A modules, and toggles cross points with an LED matrix interface.
• Matrix Switch Example. Demonstrates matrix switching on the 34904A. (The user interface for this example is the one pictured in Figure 1.)
• RF Mux Example. Demonstrates RF switching on the 34905A and 34906A.
• Multifunction Example. Demonstrates use of the 34907A module, with capabilities for controlling analog output, counter (totalizer), and digital input/output channels.

You can open this examples and see what is on the block diagram. If you have any further question I will keep my eye on this forum.

Best Regards!

The 34970A along with the 34901A board isn't that hard to use especially for measuring voltage and currents.

It is nice to have an instrument with an actual front panel.

For datalogging my colleague highly recommends the free Agilent (now Keysight) BenchLink software.

hello... thanks for your coment... Finally i get my program for acquisition... now my problem is.. how to do measurements faster? because now my acquisition data is so slow that graph advance is slow too. But i don't know, how can i do it?

What you are doing now?

[lupiita_sopa]

Hello.. well actually Im using the 34901a module is DMM, and using 6 chanels but is so slow for graph data, i want to do my sistemos faster. I think changue to take data range this is possible?

[Dennis_Knutson]

Define slow. What example are you using?

[lupiita_sopa]

I grph data, but changue evry two second and I hope changue evry second or less... because when I use only one chanel the graph changue so fast... but when i use six chanels, representatin data in graph is slow.. i need the grap data more dinamic..
