Glad to hear it. You will find all kinds of uses for a scope. Looking for pulses, glitches, noise, ripple, distortion, measuring headroom, audio frequency response, pulse widths, rise times, processor activity, input and output pulses, rf leakage, amplifier stages.

Most scopes have a calibration test point that outputs a square wave at a given voltage that is stenciled on the front panel. You can calibrate your probes frequency response by clipping the probe to the test point and setting the sweep to display a square wave. Adjust the capacitor on the probe so the corners are perfectly squared. The output voltage is usually around one volt. This should match the grid markings of one volt. Make sure the vertical gain knob, usually in the center of the vertical switch
is set to the "cal" position.

Don't try to measure an AC sine wave from a AC recepticle by putting the ground clip to either hot or neutral. A mis wired recepticle will cause a lot of sparks.

I bought 2 brandless probes from regular electronic store that has a pin, a clip and a x10 switch (x10 is relevant if your scope is 100Mhz). At the other end of the cable is a BNC connector. According to the shop keeper, BNC connector should be universal (since I'm new to EE, I am not sure about this though). Thus, a probe can be used on most brands and types of oscillescope.
