generate signal and continue execution

[shamaran]

hai guys,

im new to test stand programming and need to get some guidance for a issue im facing now.

i need to generate a FM signal and measure some reading . when i start to generate the FM signal it is in a while loop( continous generate signal). when this happen i cannot go to the next step.

can someone assist me what is the correct way to handle this situation . how can i continously generate signal( running while loop) and move to next step of the sequence

regards

Kokula,

 If this is a TestStand question you should probably post it to the appropriate board, this board is specifically for National Instruments RF measurment devices. In doing so you will find more experts in TestStand. You also need to add some details such as what software you are using to write your steps with (i.e. LabVIEW, C, C++ etc), what hardware you are controlling and what versions of software you are using.

 A couple of ways to perform the test. Write the test in your IDE that will complete the measurement in one step (basically your while loop will be in a single step) and pass or fail it using TestStand limits. Or you can for example create steps in the native TestStand while loop that goes something like a) Intitiate instruments b) set starting point for stimulus c)start the while loop d)measure reaction of DUT e) determine if it meets standard and if so exit loop, if not increase stimulus and return to d).

 There are some very good example that come with TestStand and I suggest you look at them. Start simple and build up.

Hope this helps.
