|Diff probe reading 60Vpp sine wave|
This scope probe is DC coupled, with an input impedance over 1M, and has a relatively low noise floor. A single quad op-amp chip provides input buffers, differential, and converts a single supply voltage to dual rail. My example is a x10 probe using a 12V plug pack, and will accept an input signal up to 70Vpp before clipping. Input voltage divider resistor values, and rail voltages can be changed to suit your needs.
