Risk of instrument damage due to inappropriate operating conditions
An unsuitable operating site or test setup can damage the instrument and connected
devices. Before switching on the instrument, observe the information on appropriate
operating conditions provided in the data sheet. In particular, ensure the following:
●
All fan openings are unobstructed and the airflow perforations are unimpeded. A
minimum distance of 10
cm to other objects is recommended.
●
The instrument is dry and shows no sign of condensation.
●
The instrument is positioned as described in the following sections.
●
The ambient temperature does not exceed the range specified in the data sheet.
●
Signal levels at the input connectors are all within the specified ranges.
●
Signal outputs are connected correctly and are not overloaded.
Instrument damage caused by electrostatic discharge
Electrostatic discharge (ESD) can damage the electronic components of the instrument
and the device under test (DUT). Electrostatic discharge is most likely to occur when
you connect or disconnect a DUT or test fixture to the instrument's test ports. To pre-
vent electrostatic discharge, use a wrist strap and cord and connect yourself to the
ground, or use a conductive floor mat and heel strap combination.
During operation, if the firmware observes a serious unexpected disturbance (e.g. due
to ESD), it resets all hardware components to ensure proper instrument functioning. It
then restores the user settings to the state before the disturbance and indicates the
foregone hardware reset by an "Hardware communication problem [...]" information
popup.

Bench Top Operation
If the analyzer is operated on a bench top, the surface must be flat. The instrument can
be used in horizontal or vertical position, standing on its feet, or with the support feet
on the bottom expanded.
