scxi 1100/1300 mode setup

[BjarneDK]

Hi,

Im not sure it "PXI" is the right place, but I couldnt find a place for "SCXI".

Well I have an SCXI 1100/1300, which I want to use to measure 4 signals. But when I input a signal to one of the inputs, the same appears at all 4 channels. When I look at MAX, its in multiplexing mode, so I guess thats why?

But I cant change that mode under "properties", does anybody know how to change it?

Hi Bjarne,

Have you tried to short the three other inputs while measuring one channel?

Cheers,

Hi,

Yes I just tried to short each channel (2,3,4) individually, while adding a square at channel 1, and nothing really happend. I attach a screen shot of the "biggest" change, when short channe two.

Hi Bjarne,

I not sure if you have noticed the scale of the Y-axis. Anyway there are CrossTalk/Ghosting issue here. There are a couple of things that you can try out here:

Try to aviod use AI channels that are close to each other.

Try to change/reduce your AI sampling rate.

Try to look for solutions in the following links:

Please let me know if this helps!

Thanks!

Yea I saw the Y axis, Ill try to look at the links thanks.

My setup is force and pressure measurements, I got the SCXI from another project with a 1520 (for the force measurements) with an exsisting 1100/1300 module. Besides that im using a daq 9215 for the preasure measurements.

My plan was to try to get the 1100 working to avoid using the daq 9215 and only the SCXI box.

Thanks
