Figure 3.5: Differential attenuator
For a differential input, both sides of the input need to be attenuated.
Figure 3.6: Differential attenuator matches with differential input
Standard oscilloscope probes and attenuators only attenuate one side of the sig-
nal path. These are not suitable to be used with a differential input. Using these
on a differential input will have a negative effect on the CMRR and will introduce
measurement errors.

The Differential Attenuator and the inputs of the Handyscope HS6 DIFF are
differential, which means that the outside of the BNC’s are not grounded,
but carry life signals.
When using the attenuator, the following points have to be taken into considera-
