Human Interface
The graphical user interface enables the user to operate
the instrument as simply as possible. All parameters are
displayed on a color coordinated display. The instrument
setup is intuitive. All important parameters can be easily
accessed and modified with numeric keys, cursor keys or
the twist and push button. A content sensitive online help
enables users to set up their test configurations quickly
and easily.

Specifications
Specifications describe the instrument’s warranted performance. Non-warranted values are described as typical.
All specifications apply after a 30 min warm-up with 50 Ohm source/load resistance. All specifications are valid from
0 to 55 ° C ambient temperature if not stated otherwise.
