7065 in 706 scanner

Post by bwagner » June 4th, 2013, 9:51 pm

I currently have what appears to be a defective 7065 card (~ '86 or 87 vintage and which I have not used in several years) and am looking at replacing it. Most literature I see indicates the 7065 is for the 7001 switch. I just wanted to check to make sure that any 7065 card of any vintage is still compatible with the 706 scanner. Also, do you still supply the 7065?

Thanks

The Model 7065 will fit into the Model 706. It will work in the 706 in th MATRIX mode.
Use the PRGM 0 to select the pole mode to be MATRIX. Then follow the instructions in the 706 manual for matrix operation.
Here is the link to the 706 manual on the Keithley web site.

The Model 7065 is still produced.

I am reading the application note by keithley" High Impedance Semiconductor Resistivity and Hall Effect Test configuration" and trying in same way, the difference is instead of electrometer 6514, I have two 617 Keithley electrometer. I have 7012 card in the 7001 with the use of 4x4 switching configuration.
I wonder whether the keithley engineers already tried the hall measurements, or only the resistivity measurement tried. If hall was tried what was the resistance of resistivity of the sample used. Please let me know.
We have 7065 Hall card and it has limitation of 8V compliance and is not suitable for your high resistive samples ( 200ohm cm and up at RT), Please suggest.

The Model 617 would suffice as a replacement for the Model 6514.
The Model 7065 and 7012 are basically the same.
They are matrix switching cards.
The difference is the Model 7065 has four electrometer grade buffer amplifiers that allow it to switch extremely high resistance samples.
The Model 7065 is a 4x5 matrix and the Model 7012 is a 4x10 matrix.
The Model 7012 can reliably switch samples up to about 1G ohm.
Also it can handle up to 110V DC.
The connectors on the 7012 are screw terminal of the 7012-S and cable connector on the 7012-C.

So the Model 7012 can do what the 7065 can except for the extremely high resistivity samples.
And has more voltage signal capability.
