Thanks, @Ty,

This manual reference was a helpful place to start but was only one of several commands that I had to put together to get this to work.  Here's what I landed on for everyone's benefit:
 

-- Create user generated buffer of (size)
buffer1 = smua.makebuffer(1000)
-- Collect source values output during measurement steps
buffer1.collectsourcevalues = 1
-- Assign measurement to user generated buffer
smua.trigger.measure.i(buffer1)
-- Enable trigger
smua.trigger.measure.action = smua.ENABLE

Then later:

-- Get the number of steps
num = smua.trigger.count
-- Print step source values
printbuffer(1, num, buffer1.sourcevalues)
-- Erase the user buffer when done
buffer1 = nil

I appreciate your help.

Good morning,

I am new to TSP coding.  I am setting up a 2651A to do a current pulse "sweep" (multiple current levels).  Here is the code I am sending to the 2651A (using a LabVIEW VISA Write):

-- Create a fixed level voltage sweep.
smua.trigger.source.listi({0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,0.100000,19.000000})
smua.trigger.source.action = smua.ENABLE
smua.source.rangei = 10.000000
smua.trigger.measure.action = smua.DISABLE

I have confirmed that the data is setting properly (at least I think) based on being able to read back the rangei using

print(smua.source.rangei)

which returns the expected value.

How would I go about reading back the "smua.trigger.source.listi" values to verify they were properly set?  I have tried various combinations of print() and printbuffer() and have been unsuccessful in getting a response.  I also tried creating a variable, setting it equal to the list, and then reading it back but have been unsuccessful with that.  This is what I tried:

READING = smua.trigger.source.listi
printbuffer(1,2,READING)

Can someone guide me in how to read back a setting that is a list like this?

Many thanks.
