TekScope Utility = free software

TekScope PC = has free entry level version and paid license versions too
TekScope PC Pricing and License Info

I want to be a little bit picky about the names of the software.

TekScope Utility is a Free software utility written by an Applications Engineer.
He has posts here on TekTalk that offer the download link of this *free* software.

We have a different software that does have paid license as well as an entry level free version:  TekScope PC

Yes, it can do this with the DAQ6510 and a multiplexer card like 7701.

The instrument supports scans of channels where a measure function is assigned to each channel in the scan.
Scan supports the use of the Diode Test function where we force the selected amount of current and measure V using 10VDC range.
This use of Scan approach typically gives best throughput and easy to setup.

An alternate approach is to command a channel or channels to close.  And then separately send commands to the internal DMM to config and perform measurements.  Take note that closure of backplane relays to connect to the DMM is required as well as MUX channel closure.
In the case of model 7701 and Diode Test function, close "channel" relay 35 to connect card channels to internal DMM.
The first approach using scan takes care of backplane relays for you according to the assigned measure function.
See Multiple-Channel operation in the Reference Manual for DAQ6510.

Using .list() from instrument console:

Do you have the Test Script Builder application?
If yes, at the TSP> prompt in the instrument console window you can have the full code listing of the factory KIPulse script printed out.  You can then copy and paste it to a tsp file for editing.
You'll need to load the edited version to your own script/revised function names.

At the TSP> prompt type this:

​​​​​​​TSP>script.factory.scripts.KIPulse.list()

Alternately, there are example scripts distributed with Test Script Builder or we have them posted to our Github site.

For the courageous, here comes a sample for 2450 SMU.

First: I borrowed very heavily from the data streaming example for DMM6500 posted on our github:
Github: DMM6500 Streaming

Based on that template, I modified the lua file for SMU instead of digitizing DMM.
First, take note that 2450 SMU runs much slower than the 1MSample/sec digitizing DMM.

For the SMU, I put some functions that will ramp the voltage and take a current measurement at each voltage level.
There is also a repeat count parameter in case you want to cycle.
The revised Python and Lua code for streaming from 2450 is posted here:
GitHub: 2450 data streaming

With 2400 or 2420, don’t think you’ll get there.
To have each measurement available on the PC essentially as they are available would require the PC controlling a loop.  But as you observe, loops can have timing variation and changes with CPU speed, etc.
The use of trigger model allows better timing determinism, but as you observe, the instrument cannot serve up data and carry out the list sweep.  It’s available only at completion of the sweep.

The 2450 and TSP could be pressed into using trigger blocks to have good timing control and run some code that prints the buffer data to output queue for pickup by a VISA Read.  Keeping it coordinated will be a consideration.  For example, if you do VISA read too frequently, you could get timeout errors that would need handled.

There is a nice app note and Python sample on our GitHub for data streaming from our DMM7510 of DMM6500.  Similar approach can be applied to 2450, albeit at much slower rates than the DMMs.

Maybe obvious, but this error means the 6221 does not receive the expected response from 2182A on the rs-232.

Double check the rs-232 settings are same in both instruments.
Then set LAN or GPIB the active interface on 6221.
Press delta button on 6221 and accept defaults.
Error?

Hi Niko,
See if the attached document helps with how to access Live Update feature on the graphical SourceMeter such as 2450.
