Getting started
Floating ground
Since the common input and output channels of the arbitrary/function generator
are electrically isolated from the chassis ground (the instrument chassis and
ground line of the AC connector), you can make a
fl
oating connection between
the instrument and other equipment.
All the BNC connectors are connected to the common ground, and the remote
interface connector is connected to the chassis ground.
CAUTION.
The maximum rated voltage between the chassis ground and common
ground is 42 Vp-p (DC + peak AC). When the potential voltage between the
chassis ground and common ground goes over 42 Vp-p, the internal protective
circuit will be activated to protect the circuits. However, higher voltage may cause
the internal circuits in the instrument to be damaged.
When a potential voltage exists between the chassis ground and common ground,
a short circuit from output to ground causes the instrument internal fuse to open
and the output is stopped. If the fuse opens, you need to contact your local
Tektronix Service Support.
When a potential voltage exists between the common ground and chassis ground,
short-circuiting between them may lead to excessive current
fl
ow and the internal
or external circuits may be damaged.
WARNING.
To prevent electrical shock, use this product so that the sum of the
fl
oating voltage and the output voltage of the instrument does not exceed 42 Vpk.
Do not touch the center of the BNC while the equipment is in use.
