Jog Wheel on Front Panel

[mechanical13]

I am searching for  a Jog wheel /knob of sorts for controlling user input of time/frequency on the front panel.

What I would like to do is akin to the Jog wheel that we use on ham radio stations to change frequencies/channels etc. Essentially, you can use the same wheel to turn in 0.1 Hz increments, 1 Hz increments ....and even in 1MHz increments.

We need to look at a large amount of waveform data, and I want to have the functionality of moving forward, or backward in time to see different results.

Currently, we use Labview Professional Development System 8.0.1.


Appreciate your help!!

Hi Janak,

So I thought of a decent way to do it using an event structure.  I have posted the code and it uses graph instead of a chart.  I hope it helps.

Brian,

Can you pl repost the code saved for LV 7.1 ?

Thanks a lot Brian. I think I should be able to modify it a bit and use it.

Thanks!!!
