Risk of instrument damage during operation
An unsuitable operating site or test setup can cause damage to the instrument and to
connected devices. Ensure the following operating conditions before you switch on the
instrument:
●
All fan openings are unobstructed and the airflow perforations are unimpeded. The
minimum distance from the wall is 10 cm.
●
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 correctly connected and are not overloaded.
Risk of electrostatic discharge (ESD)
Electrostatic discharge (ESD) can cause damage to the electronic components of the
instrument and the device under test (DUT). ESD is most likely to occur when you con-
nect or disconnect a DUT or test fixture to the instrument's test ports. To prevent ESD,
use a wrist strap and cord and connect yourself to the ground, or use a conductive
floor mat and heel strap combination.
For details refer to the basic safety instructions included at the front of the manual.
2.3.1 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
and LAN cables.
Note: USB cables are of varying and often poor quality. Therefore, check the qual-
ity of each individual USB cable as described in the service manual.
●
Always terminate open cable ends.
●
Use the cable R&S SMU-Z6 for connection to the DIG I/Q interfaces of the instru-
ment. The required cable is available under part number 1415.0201.02.
●
Note the EMC classification in the data sheet
