Probe Circuits

X100 Scope Probe  -  Often a typical X10 oscilloscope probe will produce large measurement errors and will influence the circuit operation.  To reduce the effect such a probe has on the circuit, I reach for my X100 scope probe, with its 100M impedance.  This probe is a commercially made device but if you want to make one, it is not hard to do. . . .
