• RE: Modernizing a legacy 2410 SMU

    Okay, perfect, thanks! I'd much rather use the 2470 version since they've got the higher rating. Very short, so you're right we'll need barrel connectors which we have.

    The wiring looks identical to the custom cable we had jury-rigged, apart from a guard on the HI Sense inner shield. The destination test fixture has the two guards on the HI Sense and Force cables shorted together, I'm thinking that shouldn't be a problem here (just a little bit extra for the HI Force guard to drive). ** Would you say it makes much difference to put an active guard on the HI Sense line or to leave it floating generally?


  • RE: Modernizing a legacy 2410 SMU

    Oh, and I should say, if you have any different ready-made cables that ARE suitable for use with the 2410 to allow triax connections, I'd be interested in those, too!
  • Modernizing a legacy 2410 SMU

    Hi,<br> <br> We're trying to convert the banana jack outputs of our 2410 SMU to kelvin-sense triax. I see that you have part 2450-TRX-BAN which is used to adapt the 2450's triax to banana. Is there any reason that we couldn't use these to do a reverse operation on the 2410? (I understand that the 2410 can potentially put out much more voltage than a 2450, so let's assume for sake of discussion that we are only operating the 2410 out to 200V....)<br> <br> Thanks,<br> Daniel
  • RE: 2600-PCT Curve tracer remediation and probe station integration?

    Thank you, Andrea! The 2657A-LIM-3 is exactly what I was thinking of. We have a 2600-TRIAX on the back of our 2601B, but I'm sure we will need a few more HV triax cables.<br> <br> Appreciate you checking on the 2601B OVP limits. Given that the 2601(A) is specifically called out in documentation to not be used, I'm a bit pessimistic. But once that word gets back I can work on getting a quote for the parts that we identify as still needing.
  • 2600-PCT Curve tracer remediation and probe station integration?

    Hi,<br> <br> We have the components for a high-voltage curve tracer - 2657A 3kV SMU, 2651 high power SMU, the 8010 fixture, a 2657A-PM-200 protection module, and a 2601B SMU (the 40V model). <ol> <li>You may have already realized the first question I'm about to ask. Our low-voltage SMU is the 40V version, whereas the terminals on back of the 8010 dictate a 210V-capable SMU. I was looking at the documentation for 2657A-PM-200 and it also specifically proscribes use of the 2601s. So, is there anything we can do to remedy this situation? Is the 2601 really going to have problems if there is a fault which engages the protection circuitry and it experiences (presumably) around 200V potential? Is the only solution such that we need to use a SMU with higher voltage rating? (I'm sure you'd rather we stick with Keithley SMUs, but presumably ANY 200V-rated SMU should work here.)</li> <li>Also, I am looking at the 2657A-PM-200 as we are trying to setup a probe station for high-voltage testing. What are the best practices for connecting the outputs of the protection module and those of the 2657A to a DUT using probes? The 2657A HI and LO outputs seem like they would work with kelvin HV triax probe holders (two cables, one for each side). But the 2657A-PM-200 has that combined LO sense/force output, along with the Kelvin HI channel. Can a third kelvin HV triax probe holder be used to carry the HI side of the low-voltage SMU (for example, as MOSFET gate control), and then what do we do with the LO side of the SMU?</li> </ol> <br> Thanks,<br> Daniel
