The time has come to buy an oscilloscope for myself. My last use of one being a Textronics tube unit in school in the 80s, so I'm not a "beginner" but my oscope knowledge is a bit dated (ha). After reading MANY threads, some here, and watching way too many videos, I am probably more undecided now that before. LOL. Maybe a Rigol MSO or DHO unit? I'll spend what is needed, but I don't want to go overboard paying for sensitivity I don't need.
Here are the main things I need it to be able to do:
1. Monitor single digital signal pulses (3.3v) on the output of the teensy 4.1 microcontroller I'm using for a coil driver project. It's currently running at the stock 600 Mhz, and the pulses I'll be outputting will be no less than about 50uS. Four digital outputs to a pair of coil drivers at a time.
2. Then monitor the output from the two coil drivers to the MOSFET gates (full H-bridge). 12v above the coil voltage source for each output. Four outputs total - although only two active at a time!
3. Then monitor the output / response of the two ends of the driven coil. Single pulses only, not PWM. No more than 150v (input is 120v) from ground, zener overshoot limited. Two of these with two of #2 at the same time would be optimum.
1 and 2 are to confirm programming / circuits are driving the FETs as intended. 3 is to see how the coil actually reacts (versus what I think it will do based on simulations).
My goal is to be able to verify the timing and output voltage to get the optimum pulse energy-wise (battery source) into the coils (four wired in parallel) to produce the exact amount of magnetic flux required for this POC project. In the future, it would also be nice to be able to decode/save CANbus traffic, but that it not a requirement for now.
Thanks in advance,
Bryan
