3.2
Choosing the operating site
Specific operating conditions ensure proper operation and avoid damage to the
product and connected devices. For information on environmental conditions
such as ambient temperature and humidity, see the data sheet.
3.3
Setting up the converter
The frequency converter is designed for use under laboratory conditions on a flat
bench top or mounted on a wafer probe station. Four M8 threads are provided on
all long sides of the converter to allow for mounting the converter on a flat sur-
face. Some on-wafer measurement applications can require the converter to be
tilted to bring the test port closer to the chuck. In these cases, an additional bent
waveguide adapter can be necessary in front of the test port adapter to compen-
sate for the tilt angle.
Adjusting the feet of the converter
The instrument can be used with four feet attached to the respective bottom side
(depending on the orientation). When the DUT is mounted between two convert-
ers (see
on page 14), use the feet for alignment of the com-
plete setup. A bubble level can help you to align each converter horizontally
before fitting the DUT.

Considerations for test setup
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded RF cables.
●
Always terminate open cable ends.
