I am going to need to take current readings on my oscilloscope soon. I googled Tektronix Current Probe and the results are (monetarily) scary. Do I need to use a tektronix probe with my tektronix scope? Even the other brands are expensive. I could use a hall sensor I guess, but it might be too big. So, how do you guys (on a budget) measure the current through a MOSFET leg?
