Will this measure these ranges?
29khz to 20Mhz.
Want to test some timing circuits for microcontrollers.
RC circuit, crystal w/capacitors and oscillators.
Oscillators are 4 lead. I call them 'can' type.

I have found it does well up to 5Mhz.
Are you asking about these can Oscillators:

Very easy to probe. Four pins, 5V, GND, and output.
Yes.
Let me ask about the 2 legged can first.

My understanding is that it will run without cap's if it is connected to the Stamp;
Is that the way you see it?
A pair of cap's will make it more robust though.
Err, no.
A 2 legged part is just a resonating element, it needs to be part of an amplifier loop to actually oscillate.
- so, no you cannot 'connect to the Stamp' - Stamps already have their own, on board resonator & those pins are not user accessible.

That is all well in good but it is actually a PIC16F54.
That is the little brother to the 16F57 which the Stamp 2 DIP is made from.
With the Parallax Oscilloscope we would like to take some readings.
Found out crystal gets enough capacitance with the PIC to work.
You need to specify accurately what you mean when posting so as to eliminate misunderstanding. A PIC is not a BASIC Stamp and vice-versa. They are two very different things, even though some BASIC Stamps incorporate PIC microcontrollers.
