Question :

I cannot see my signal on the Oscilloscope. What can I do?

Answer :

You have many options to help diagnose this issue, below are a few suggestions to get started. If you find yourself needing more help, please connect with our Technical Support Center. You can get started by pressing the "Contact Us" button on the right side of the screen.  

1. First, you will want to make sure your oscilloscope is working properly. Use a passive probe, preferably the one that came with the oscilloscope, to connect to the probe compensation on the front panel of the scope.

2. Do a factory default setup, then Autoset the scope. At this point, you should be able to see a 1kHz square wave. If you do not, then check your connections. If you still do not, run any diagnostics that may be available on your oscilloscope.

3. If you do see the probe compensation signal, then basic operation of the scope is working properly. Connect your signal again, and try the Autoset button again. If you still do not get your signal, try setting the vertical and horizontal scales to values that are appropriate for your signal. For example, if you have a 5 volt sine wave that is 10kHz, then set the vertical scale to 1V/div, and set the horizontal scale to 40usec/div. Also, make sure your trigger is appropriate. For the example 5 volt sine wave, setting the trigger level to 2.5V would allow the scope to trigger on that signal.
