Your post seem off topic, so I created a different thread for managing 4200A-CVIV switch.  <br>

In Clarius software, be sure to make use of an Action to route the SMU or CVU to the output.<br>
Execute the Action before you attempt to perform the SMU or CVU measurement.<br>
In the Select ribbon, search for a project using "CVIV" as the search term.<br>
Those projects will include the Action steps for configuring the CVIV prior to a measurement.

Hello,<br>
<br>
The HV-CS-1613 is just a feedthrough or barrel type connector utilizing our HV Triax connector type on both ends, so do not think it will be what you want either.<br>
<br>
For the double pulse test, I suspect you are using the SMU just to charge up the capacitor bank, right?<br>
I imagine that measuring very low currents with the 2657A is not important to this application.<br>
Therefore, you could make use of two cables of model SHV-CA-553-x (x is the length in meters).<br>
One end of this cable has the proprietary HV Triax connector that will connect with the HI or LO at rear of 2657A.<br>
The other end is an SHV Plug connector.<br>
Your PCB or custom test fixture could then make use of commonly available SHV Jack connectors.<br>
Google 'SHV Panel Mount' to get an idea of what the open market offers for SHV.<br>
<br>
<br>
You mention having an 8010 test fixture and the HV-CA-554 cables already to connect the 2657A to the 8010.<br>
If you want to continue to use those cables, but you need a means to connect to a custom test fixture or PCB board rather than to the 8010, consider using the HV-CA-571-3 feedthrough with unterminated triax.<br>
Alternately, there is a PCB mount HV-CS-1589 that might also work for your situation.

Just confirming you have the older 3706 and not the 3706<strong>A?</strong><br>
<br>
 Assuming 3706, page 7-2 of User Manual has the upgrade instructions.<br>
(https://www.tek.com/en/switching-and-data-acquisition-systems/3700a-systems-switch-multimeter-manual-3)<br>
<br>
With the thumb drive inserted, you need to use the menu to navigate to the UPGRADE screen.  Then the content from the thumb drive will be applied.<br>
The two files that you placed will cause any "autoexec" application of the firmware update.

Can you clarify which forum post gives you this error?<br>
The posts you have pertaining to Clarius install seem fine to me;   not errors to display.

You may want to revisit the idea of using 2W for the high ohms channel.<br>
When a measure function is associated with a channel, then when closing that channel, all the required channel pairing (in case of 4W) and backplane relays are managed for you.<br>
So a scan that uses both 2W and 4W will mange the backplanes appropriately for the closed channel.<br>
<br>
If using a scan with mixed measure function type, I'm able to reliably measure 50MΩ (2Wire) and 0.5Ω (4Wire) on two different channels.  See attached.<br>
<br>
If not performing a scan and attempting use of 4W with the 50MΩ, I find extra settling time is needed.<br>
I'm not able to find a command in the IVI driver.  So using the WriteString() to send:  ":ROUT:DEL 0.25, (@106)"  to obtain an extra 250msec on channel 106.<br>
<br>
See attached for info on both defining a scan or the single channel read approach.

If you want to connect the two meters together without soldering a cable, need three items:<br>
triax cable to 6430 preamp (7078-TRX-3)<br>
Insert 237-BNC-TRX into end of 7078-TRX-3 cable<br>
Put 7078-TRX-BNC triax to BNC adapter onto 6517B;  attach the cable.<br>
<br>
If you want to make your own, see attached image.

How long are your cables from the 7707 and the devices?<br>
<br>
Also, for the high ohm channel, can you instead use 2W ohms mode?<br>
I suspect part of the settling time issue will be for charging up the remote sense lines.<br>
For 10M-Ohm and higher DUT value, the use of 4W is of negligible benefit and in this case might be giving you a longer settling time problem.

For topic #2, check the state of your interlock.  I suspect that is not engaged and it is normal for the instrument to clamp the output below ~42V.  In your case, you are hitting the voltage clamp level and so the current forcing is not the primary action of the SMU any longer;  the actual current will be the clamped V / DUT R.<br>
<br>
For topic #1, error 5111 is because the measure time will exceed the requested pulse width.<br>
Try setting the NPLC to minimum of 0.01 which for 60Hz power equates to 166.7usec.<br>
Make sure you turn off the source readback;  that defaults to ON which means two measurements occur (one for V and one for I) which at 0.01 NPLC puts you past the 250usec pulse width.  Turn it off so that if forcing I, it only measures V and does not also read back the source level.<br>
Source or Measure Delays could also be playing a role;  set them to zero.<br>
<br>
Last:  make sure your firmware level is up to date.  1.7.12b is current release.

Hi Daniel,<br>
<br>
Interesting combination of products you have.  Too bad the gate SMU is 2601B and not 2611B.<br>
I'm conferring with factory about the 40V models and if the ~200V OVP is sufficient.<br>
<br>
<br>
For the handling of the LO and Sense LO from the 2657A and the 2601B, we do have a "ground unit" accessory item:  2657A-LIM-3.<br>
A single triax cable from the SLO/LO connector on each SMU is brought to the LIM-3.<br>
The LIM-3 then provides output connectors for the combined LO and separately for the combined SLO.<br>
the LIM-3 also provides interlock hub.<br>
<br>
<a href="https://www.tek.com/en/default-accessory-series-manual-29">Info on the 2657A-LIM-3</a><br>
<br>
Let me come back to you concerning the 40V model.<br>
<br>
Do you have any of the 2600-TRIAX accessory items to convert the 8-pin Phoenix connector to three triax for the gate SMU?<br>
