÷100 attenuation obtained using the external ÷
attenuator. The probe is automatically set to
÷
internally when the
external attenuator is installed. The internal
÷
attenuator cannot be selected when the external ÷10 attenuator is installed.
Adding Offset
The AP033 has true differential offset capability. This allows you to remove a DC bias voltage from
the differential input signal while maintaining DC coupling. By using probe offset rather than the
“position” control on the oscilloscope, the full dynamic range of the probe remains centered
around the offset level.
