I've done basic electronics and microcontrollers but I'd like a point in the right direction. What type of equipment should a newcomer consider to investigate the signals of existing electronics?
For example, my first project would be to try to decipher and understand the signals and pinouts on the vintage 20-year old autopilot on my boat. The autopilot consists of a central control box with connections for a heading compass, control head, and rudder position indicator. The rudder position unit's specs show a frequency of 3400Hz for center with +/- 20Hz for each degree of rudder angle. Can I verify that signal with an oscilloscope (never used one)? If so, what type? To save money, are the USB units that work with a PC a good option? Thanks.
