I need to do some research on this.
In meantime can you confirm:  are you trying to operate in quadrant 1 (positive current, positive v), or quadrant 4 (negative current, positive V).
Related to this, is the device active or passive?  Does it have an open circuit voltage above 20V?
 

I agree with your pinout definitions with one exception.
The orange DC/Pulse connector for the 10usec current pulse is not guarded.
Consider the unused pins to be open.

The green connector is essentially a 2601B SourceMeter.  Same pinout.

If I may revisit the idea of using the 2601B-P-INT:
if using the instrument to excite laser, the -P-INT gives you an interlock to integrate with your safety scheme.

It also gives you a single set of connections for SMU or Current Pulser.

It is correct of you to point out that when routing the SMU on the BNC output of the -P-INT, the SMU guard voltage is on the outer shell of the BNC cable.
But this is a max 40V SMU instrument, so this does not generally pose a safety concern and especially if the cables are already inside of the light curtain safety barrier.
At 40V and less, it is very economical way to get the benefit of a guarded cable and improved settling times and less cable leakage.

Consider using the 7078-TRX-BNC to reconnect the BNC outer shell to the triax inner shield which typically carries guard of a SMU instrument.

 

The 2601B-PULSE is designed for connections through the 2601B-P-INT and the four BNC that it presents.

Can I ask the reason you want to separately connect to the DC and the Pulse output connectors?

I do not recognize that as any sort of dependency for the Flash Wizard application.
But it is a rather old utility and does use some shared Microsoft objects/components.

Do you have Microsoft Office installed on your computer?  If yes, what version?

What version of Windows OS is on this system?

Any chance you can try it from a different computer?
FlashWizard has been around a very long time.  I've recently verified it on Windows 11, so that and earlier Windows should be OK.

On the graph view, where you have data, what is name of the Active buffer.  Go to Data tab once Graph view is displayed.

Do your trigger blocks make use of same buffer name?

Hi Maia,
I'm going to ask the factory to take a look at this.
Excellent detail here and steps to duplicate.  Thank you for taking the time to put it so clearly.

I suggest you examine the Quick Start Guide, User Manual and Reference Manual, in that order.

All those can be downloaded from tek.com:  Manuals for 2611B SourceMeter

Quick Start Guide attached to post.

The instrument is shipped with a mating connector and hood/strain relief for making a cable for the SMU channel.
This connector has simple screw terminals to receive your wires from the LED device.

Both the User and Reference have section on DUT connections with pin identification for the connector, etc.
For LED device, recommend to use 4-wire connections.

If you do not want to fabricate a cable of your own using the supplied mating connector, consider the 2600-BAN cable.
Check that the sheathed 4mm banana connectors that it presents are compatible with your LED connection requirements.
There are numerous banana adapters to clip lead and similar on the open market (Pomona, Mueller, etc.).

How are you planning to operate the instrument?  Manually or software?  Does the SMU need to coordinate with any instrument such as light meter, etc.

If just wanting the SMU to do IV curve and not wanting to write any software, consider the KICKSTARTFL-IVC application module of KickStart.
You can connect the 2611B to the PC on USB, LAN or GPIB and use KickStart.  RS-232 is not supported by KickStart and 2600B.

For the 2182A, in Chapter 11 of the User Manual, the error codes are defined.
Error -101 = invalid character
Error -102 = Syntax error
Error -410 = Query Interrupted

The first two indicate you are sending invalid commands to the instrument.
The -410 just means you sent a query type command (one that ends in question mark), but did not fully read the response before sending a new command.  Even use of *IDN? query command can cause the -410 if you do not read the identify yourself response before sending new command.

To know which command is wrong/causing error -10x, LabVIEW has some single step debug features.
Or, install the NI IO Trace tool and invoke that.  It captures the bus traffic between your LV and and the 2182A.
You can see which command causes the error condition to be raised.

When using LAN based connection to KXCI, it is normal for every config command you send to respond back with ACK\0.
Pg 2-11 in the KXCI Remote Control Programming manual shows ethernet based write and read examples.

For example, sending ME\0 command, the 4200A will respond back with ACK\0

In your code, if using LAN to KXCI, plan to do a write + read for every operation to pull the ACK\0 off the bus.

I think you are just having a lot of backlogged ACK\0 in the output queue that need to be read and this is why you do not get expected response to the SP or the DO commands.
