a dangerous voltage. It will also influence the measurements
and create measurement errors.
•
do not connect the outside of the two BNC’s of the attenuator
to each other as this will short circuit a part of the internal
circuit and will create measurement errors
• do not connect the outside of the BNC’s of two or more at-
tenuators that are connected to different channels of the Han-
dyscope HS4 Diff to each other
•
do not apply excessive mechanical force to the attenuator in
any direction (e.g. pulling the cable, using the attenuator as
handle to carry the ATS5004D, etc.)
3.1.2 Differential test lead
The ATS5004D comes with a special differential test lead. This
test lead is specially designed to ensure a good CMRR.
The special heat resistant differential test lead provided with
the ATS5004D is designed to be immune for noise from the sur-
rounding environment.
3.2 Sampling
When sampling the input signal, samples are taken at fixed inter-
vals. At these intervals, the size of the input signal is converted to a
number. The accuracy of this number depends on the resolution of
the instrument. The higher the resolution, the smaller the voltage
steps in which the input range of the instrument is divided. The
acquired numbers can be used for various purposes, e.g. to create
a graph.
