4. Fitting of the HO720
Precondition!
The installation of the interface HO720 is meaningful only if,
as described under point 3 (Firmware), the oscilloscope has
fi rmware version 03.000-yy.yyy or higher. Otherwise the in-
terface is not recognized by the oscilloscope. With spectrum
analyzers the interface will be recognized by each fi rmware
version.
STOP
Safety!
The following procedures must only be carried out
on condition that the mains (line) power cable is not
connected to the oscilloscope and/or the spectrum
analyzer and no connection is made at the mea-
surement inputs.
STOP
Attention!
To avoid damage of the interface during removing
and fi tting by electrostatic discharge, please link a
metal part of the oscilloscope / spectrum analyzer
to equalise potentials between oscilloscope / spec-
trum analyzer and your body. Maintain this connec-
tion during the fi tting/removing!
Only touch the interface at its mounting panel!
4.1 Removing the existing interface
4.1.1
Remove both fastening screws.
4.1.2
Pull out the interface.
4.2 Fitting the interface HO720
4.2.1
Insert the interface HO720
in the opening in such a way, that
the PCB will be inserted in the
guides – visible on both sides – and push it in completely.
4.2.2
Fit the interface with the fastening screws previously (item
4.1.1) removed.
