When I said the "power" of the signal, I meant (for your application)
the voltage. You need to set the vertical range of the digitizer
to account for the expected voltages of the signal you will measure.
When you set the Key Navigation for a tab control, it selects the
entire control, not specific tabs. To navigate between the tabs
on the control, simply use the arrow keys on your keyboard.
If you want to jump from one tab to another programmatically, you need
to create a property node for the tab control and set the Value
(Signaling) property. This changes which tab is displayed.
To create the property node, right-click on the tab icon in the block
diagram, then select Create >> Property Node. I am
attaching an example for you.
Like I said before, programming your application to recognize and
respond to an external beep is much more complicated than you
think. A microphone will not send a digital signal, but rather an
analog signal representing the sound. You will need digitizer
(like a National Instruments MIO, DSA, or High-Speed Digitizer device)
in your machine to digitize this signal and bring the data into
LabVIEW. At that point, you will have to analyze the data to
determine if there was a beep. This will probably not be a simple
task because you have to distinguish the specific beep from surrounding
noise and other sounds. There are many different ways to design
this system, but these forums are not an appropriate place to discuss
this.
Also, I do not believe these forums can continue to provide the help
that you need. Most issues are handled in one or two replies,
because they deal with specific, limited issues. Your threads are
spanning dozens and dozens of posts because you require assistance at
every level of your project. These forums are not intended to
require specific members of the community to provide ongoing
consultation to application development.
For you to be successful, I recommend that you arrange to take a NI Customer Education class or seek out a 3rd party consultant.
You should not post questions to the High-Speed Digitizers forum unless
they are about High-Speed Digitizers or the NI-Scope driver software.
Good luck.
