ESD Protective Measures
To protect the extension unit against damage due to Electrostatic Discharge (ESD) use
the wrist strap and grounding cord supplied with the network analyzer and connect
yourself to the GND connector at the front panel of the R&S
ZVA or R&S ZVT. For
details refer to the Quick Start Guide of your analyzer.
USB Connection to the Analyzer
●
The extension unit is intended for direct connection to R&S ZVA or R&S ZVT net-
work analyzers according to the instructions in Chapter 3.4.5, "Connecting the
extension unit to the R&S ZVA/ZVT" , on page 22 and in the analyzer’s help sys-
tem. Do not connect the unit to other USB hosts, e.g. a PC, and do not insert any
USB hubs between the analyzer and the unit, as this may cause damage to the
unit or the host.
●
It is safe to connect or disconnect the extension unit while the network analyzer is
operating. Never connect the unit during a firmware update.
