First step is to understand (1) what you have and (2) what you need.
So, If the spindle revolves one time, How many cycles of the sin wave do
you see? What is the amplitude of the sine wave (in volts peak to peak)?
Does the amplitude change with the spindle speed?You need to either

Chris. I'm still learning electronics. Could you expand a bit on this
please.
Maybe draw a napkin sketch of it. Sorry to be a bit slow on the uptake

Yes, you do need a special PC. This means a PC you use for Linux CNC and
not the one already on your desk. Again think of the normal ink-jet
printer. Do you connect it to a special "printer PC" that is only used to
drive inkjet printers? No. In most cases, the inkjet (or laser)

halscope shows logic 0 and logic 1. It has no way to display voltage.
