So I 'broke my teeth' on Netduino in the micro world. Got hooked, and haven't looked back.

I've recently got my hands on a LeCroy Wavejet 312 Oscilloscope from an Electrical Engineer friend, and I'm really excited.
But I have NO IDEA how this thing works.

Some very quick googling has returned not much good stuff, so I was hoping to pick your collective brains.
I don't even know where to start with this thing:

• What can I do with it?
• How do I use it?
• Are there any very simple examples you may know of?
• I have a rotary encoder, and I would like to watch the detents change, can I do that with a scope?

Any help would be awesome, as I feel this will definitely help me improve my skills in the hardware world.

P.S. Please Please Please let me buy a N+2 in Canada!!

Have you tried the Getting started guide? I guess the best way is to ask your friend for 10-minute introduction/demonstration. The basic control of an oscilloscope is almost universal, it is the details which make the difference. To inspect rotary encoder waveforms, you'd need to do something like

• Attach two probes to the oscilloscope, channel 1 (usually yellow) and channel 2 (usually cyan),
• Connect each probe tip to the encoder output, ground wire to the circuit ground,
• Enable both channels by pressing buttons "1" and "2", if not done already,
• For each channel set horizontal scale to about ten milliseconds per division, set vertical scale to about one Volt per division,
• Set trigger to falling or rising edge, source channel 1 or channel 2, level to about 2 V (not really important),
• Start capture with Auto, Normal or Single button.

You can do a lot of things with such device

And watch this video before you try to use it as a multimeter.



Do not watch more that one video from this site per day, you end up talking like this guy if you do...
