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 prevent electrostatic discharge, use a wrist strap
and cord and connect yourself to the ground, or use a conductive floor mat
and heel strap combination.
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 infor-
mation on appropriate operating conditions provided in the data sheet. In
particular, ensure the following:
●
All fan openings are unobstructed and the airflow perforations are unim-
peded. 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.
4.1.1 EMI Suppression
Electromagnetic interference (EMI) may affect the measurement results.
To suppress generated Electromagnetic Interference (EMI),
●
Use suitable shielded cables of high quality. For example use double-shielded
RF, BNC and LAN cables (CAT6 STP).
Note: USB cables are of varying and often poor quality. Therefore, check the
quality of each individual USB cable as described in the service manual.
●
Always terminate open cable ends.
