Multiple loops

[karan_maverick]

Hello. I am trying to create a nested loop structure for the front panel of vi for HP 4140B pico ammeter. The algorithm is as follows

Initialize Va limit

              time step

              select wavefrom type

              time delay

Start

0 to Va

Next

Va to 0

Next

0 to -Va

Next

-Va to 0

collate data

print graph and save to a text file.

Now the instrument does not have multiple sweeps either it is ramp up or ram down , staircase up or staircase down or D.C. So either through loops I can do it or trigger the D.C at various levels with conditions and counters and colate the data.

Any advise on how to implemet it. I am using the library which I downloaded from the ni.com. Links to multiple loops examples will be very helpful.

Regards

Hi Karan,

Is the VI you posted what you have done so far? You should consider using a state machine structure for each ramp up and ramp down.

Hope this helps!
