Tektronix offers over 100 different probes to meet your application needs. The first step to proper probe selection is to consider the signals you plan to measure. Do you need to measure voltage, current or both? What frequency is your signal? How large is the amplitude of your signal? Does the device under test have low or high source impedance? Do you need to measure the signal differentially? Answers to these questions will allow you to pinpoint the best probing solution from the many probe types that Tektronix offers.
