The Max Voltage listed on the front of the electrical sampling module refers to the maximum voltage that can be applied without damaging the modules. For the 80E01 and 80E06, the Max Voltage is ± 2V pk-pk. For the 80E02, 80E03, 80E04, the Max Voltage is ± 3V pk-pk. This is not to be confused with the dynamic range of these modules. The dynamic range is 1V pk-pk. Dynamic range indicates the amplitude that can be applied without clipping the incoming signal.
