How do I determine if a TDMS Channel exists for an IIF command

[Dfjjbn]

I am filling out a Spread sheet block in a Template PDF with Test data. The tests can be run at multiple input voltages, but sometimes only one voltage.  When only one voltage is run, the only data in the TDMS file is that data.

Hi Dfjjbn,

And yet the channel that is sometimes missing is the "Current" channel, per your posted Calculator expression?  How does the "Current" channel existing or not factor into how many voltage set values are recorded in the data set?

What is a "Spreadsheet" block in DIAdem?

What is a "Template PDF" in DIAdem?
