7709 Connection Question

This is probably a really simple question, but I was just wondering first off what exactly does the Model 7709 come with? Does it come with a connector and ribbon already combined, or do we just get a connector by itself? And if we were in need to buy parts for it, which connector/ribbon would be su...

Re: Van der Pauw resistivity measurement options

After reading the manual for the 2700, I found out that there is a 4-wire measurement option for resistance. Does this compare at all in terms of accuracy to actually using the 6221/2182A pair?

Just trying to expand our options.

Re: Van der Pauw resistivity measurement options

Thanks for the reply.

The measurements should be on the low side, so we will probably go with one of the first two options you mentioned. However, I'd like to ask, is there any advantage to either of them?

Van der Pauw resistivity measurement options

We currently have a 6221 AC/DC current source and a 2182A nanovoltmeter. What would be our best option to measure resistivity using the van der Pauw method? We have been looking at the 7001 switching system and the 7012 card that goes with it, but perhaps there are better, and perhaps cheaper, alter...
