1 Safety Instructions
This vector network analyzer has been designed and tested in accordance with the EC
Certificate of Conformity and has left the manufacturer’s plant in a condition fully com-
plying with safety standards.
Risk of instrument damage
To prevent instrument damage make sure to read through and observe the following
safety instructions.
ESD protective measures
To protect the network analyzer and the external test sets against damage due to Elec-
trostatic Discharge (ESD) use the wrist strap and grounding cord supplied with the net-
work analyzer and connect yourself to the GND connector at the front panel of the ana-
lyzer. For details refer to the R&S ZVA Quick Start Guide, stock no. 1145.1090.62.
Input powers RF IN and LO IN
The RF input power at the connectors RF IN and LO IN must not exceed the maximum
values quoted in the data sheet. The maximum values are below the maximum RF source
power of the network analyzer. The "ZVA80-BU" mode ensures compatible source pow-
ers.
Before you connect your external test set to the network analyzer, always activate the
"ZVA80-BU" mode using the "Frequency Converter" dialog (see
the ZVA80-BU Measurement Mode"
Avoid heavy shocks
Heavy shocks can damage inner parts of the devices. Shock-proof packing should there-
fore be used for storing or dispatching the analyzer and the external test sets.
Opening the instrument
Do not open the frequency converter and diplexer elements of the external test sets.
Repair can only be done at the manufacturer's servicing department.
Using frequency converters separately
The frequency converters may be dismounted from the external test sets and used sep-
arately; see
chapter 4, "Dismounting Frequency Converters"
guide flanges of the dismounted converters and of the test port adapters must be pro-
tected against mechanical damage. Furthermore the waveguides must be shielded from
dust.
Protect the waveguide flange of the dismounted converter by leaving a test port adapter
connected. When the converter is not in use attach one of the included protective caps
to the adapter. Avoid scratching the contact surfaces of the waveguide flanges.
