Using the GN610 and GN611

WARNING
High bandwidth and measurement cabling
Due to the high bandwidth measurement capabilities of the acquisition board
in combination with the high measurement sensitivity of the board it is important
to pay close attention to the measurement cabling.
Some advice to prevent measuring unwanted disturbances:
Keep measurement cables as short as possible in order to reduce the
l
reception of environmental disturbances.
Use shielded cables. The cable should have the measurement cables
l
paired inside a shield. Preferable the shield is connected to the chassis of
the measurement Genesis High Speed equipment or alternatively the
chassis of the object under test.
Figure 12.1: Shielded cable
(1) Use HBM 1-KAB290-xxx. These cables are designed to meet this
setup.
In case of high frequency disturbance where high bandwidth measurement
l
is not required one can reduce the measurement bandwidth by using the
lowpass filter of the acquisition board.
In case unshielded cables are used keep them as close together as
l
possible, i.e. position them next to each other (to keep the loop small).
