Connecting cables, risk of damage
A full set of connecting cables including the necessary adapters (for instrument types 03
and 04) is supplied with the R&S ZVA80. It is strictly recommended to use these high-
quality cables for the RF connection. For accurate measurement results, RF cables must
have a low attenuation and excellent phase stability.
Tightening the cable connectors too much may cause damage. Loose connections can
result in inaccurate measurement results. For these reasons always use appropriate tor-
que wrenches, suitable for the different connectors types. A torque wrench for the delicate
1 mm connector is supplied with the R&S ZVA80.
Some of the RF connections are only used while the network analyzer operates in the
low frequency range (below approx. 50 GHz) or in the high frequency range (above
approx. 50 GHz). It is strongly recommended though to establish all RF connections, as
this ensures full flexibility and maximum accuracy .
1. Ensure that the converter is in standby state or disconnected from the power supply
(see chapter 2.4.3.1, "Standby Switch" , on page 13).
2. Ensure that the "ZVA80-BU" mode is activated at the network analyzer (see chap-
ter 3, "Basic Operation" , on page 23).
3. Connect the RF input and output connectors of the diplexers and the frequency con-
verters as shown below.
The following figure shows the cabling of the left test set.
