1 Safety Instructions
This frequency converter 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 frequency converter 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 analyzer. For details
refer to the Getting Started guide of your analyzer.
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 frequency converter mode ensures compat-
ible source powers.
Before you connect your converter to the network analyzer, always activate the fre-
quency converter mode using the Frequency Converter dialog (see
vating the Frequency Converter
type and connecting diagram.
Protection of waveguide flanges
The waveguide flanges of the converter and of the test port adapters must be protec-
ted against mechanical damage. Furthermore the waveguides must be shielded from
dust.
Protect the waveguide flange of the converter by leaving a test port adapter mounted.
When the converter is not in use attach one of the included protective caps to the
adapter. Also attach protective caps to the second test port adapter. Avoid scratching
the contact surfaces of the waveguide flanges.
Avoid heavy shocks
Heavy shocks can damage inner parts of the instrument. Shock-proof packing should
therefore be used for storing or dispatching the frequency converter.
Opening the instrument
Do not open the instrument. The converter must be repaired at the manufacturer's
servicing department.
