RE: MDO3014 Double Pulse Test
Try setting up scope to trigger on CH1 level and connect the AFG output to scope CH1. Perhaps have the AFG output simple square wave of similar amplitude to what you will use for DPT. When able to capture that, move to the DPT waveform. -
RE: 2450 High voltage
When the instrument reports value of 9.9e+37, it is indicating an over-range condition.
Since you are forcing voltage, is very odd to have a reported over-range for voltage as the voltage measure range will follow the source range. For the sweep up to 5v, it should be selecting 20V range.
Try this: reboot and do not yet connect from remote PC. In local operation, the instrument will continuously update the V and I measurement to front panel. Even with the output off (blue light not illuminated). What voltage does it report? Near to zero or over-range?

RE: 2450 High voltage
I notice your script is asking to use the sense HI and sense LO/4-wire connections for the voltage measurement.
Are those connected to the DUT?
Try setting it to 2WIRE. -
RE: Running measurement customizable scripts on Keithley 2636 via Python (PyVISA) - Speed problems
How goes the project with the 4 SMU channels?
You can treat the A and B versions the same from command set standpoint.
Are you putting them on TSP-LINK and connect PC to just one of them?
For fast performance in the source + measure actions, using trigger model is way to go.
But this means place the data into buffers.
Most typically, the data is available when the trigger model task completes.
Your script/collection of commands could just print the data or you can have PC send a printbuffer() command.
So the task shifts to coordination of the 2600x trigger model with the PC/Python.
With the script writing feature of TSP, you can bundle the trigger model definition commands in a function that is loaded into runtime memory. You can define parameters so that the function is flexible. Also make a run_it() function. Then your Python code does not have to send a lot of characters for each time you run it. -
RE: Running measurement customizable scripts on Keithley 2636 via Python (PyVISA) - Speed problems
A couple comments and a file attachment that may help.
Example 3 in the attachment has some Python snippets and TSP code.
Comment 1: if your model is 2636 without any letter suffix after, it does not support the smuX.trigger.xxx commands.
Comment 2: check the readings/sec rate supported by the model for various settings (datasheet has them). 1 usec reading rates are way too fast of an expectation. -
RE: error in using TekPWS4000 (Tektronix.TekPWS4000.Interop)
Are there C# examples distributed with the IVI driver? How are those?
Does driver support 64-bit target? -
RE: Keithley DMM7510 2-Wire RTD Feature request
In meantime, can you use 4-wire RTD mode, but jumper the sense hi to HI and sense LO to LO at the DMM terminals and then connect your 2-wire sensor -
