What factors decide the DSO probe pricing ?
The probe bandwidth, and function decides its pricing.
According to the function, there are many probe categories, including high voltage probe, differential probe, active high speed probe, and etc. Different probe category pricing ranges from less than USD10.00 till USD10,000.00.
The probe acts as the connection media of circuit to oscilloscope, a high fidelity signal output is a must - considering this, even for passive probe, its inner structure get complicated parts to compensate the circuit.
