Figure 3.4: Differential input
Standard oscilloscope probes and attenuators only attenuate
one side of the signal 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.
Figure 3.5: Differential input
The Differential Attenuator and the inputs of the Handy-
scope HS4 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 consideration:
•
do not connect other cables to the attenuator than the ones
that are supplied with the instrument
•
do not touch the metal parts of the BNC’s when the atten-
uator is connected to the circuit under test, they can carry
