variable measurement series

[mkossmann]

How to do variable measurement series with TestStand ? We've allready some measurement modules available as dll written in CVI. Each measurement module has a set of parameters to setup the UUT like channel, resolution, origin and power and return one Measuerement value. Now the operator should be able to choose a measurement series over a subset of all parameter variations at runtime of the testsequence, i.e. measure over every fitfh channel, one resoultion, two power levels and one origin. And the next time measure only every tenth channel, but over three resoultions.

I've allready found , that you should be able to build a new sequence dynamically at runtime of the sequence using the TestStand API and found the sequence builder example and some example code for CVI  in the forum here.

Do you know of other, more detailed examples for CVI ? Or is there another option to do that ( without the need for a Teststand development license on the system running the sequence) ?

Hi,

Take also a look to this Thread:

there someother links to threads that might interrest

You could pass data configuring your measurement to your CVI code module. The data can be operator-created, calculated by "Statement" or by per-step "Expression". In this example, the flexibility required by your application is contained in the CVI code module, that allows various settings.

Another approach is to have several CVI code modules with fixed measurement settings. You could operator-driven launch these modules with "Goto" or other flow control step types. In this example, the flexibility required by your application is contained in the sequence. With this approach, no development license is needed.
