| - | BNC probes are used to enable the measurement of higher voltage signals than what an oscilloscope can typically measure. A probe achieves this by changing the input impedance seen by the oscilloscope which is done by attenuating the signal, usually by a factor of 10X. The Analog Discovery tools can only display a maximum of 50 V peak-to-peak (limited from -25 V to +25 V), so it would not be able to safely measure a 200 V signal. The scope leads from Digilent are able to handle that voltage and can also use the 10X attenuation to instead present a 20 V signal to the Analog Discovery | + | BNC probes are used to enable the measurement of higher voltage signals than what an oscilloscope can typically measure.
