8 Reference Approval
8.1 Reference Equipment for Type Approval
The Cinterion Wireless Modules reference setup submitted to type approve PXS8 is shown in
Figure 11. The module (i.e., the evaluation module) is connected to the DSB75 by means of a
flex cable and a special DSB75 adapter. The GMS/UMTS/CDMA/GNSS test equipment is con-
nected via edge mount SMA connectors soldered to the module’s antenna pads.
For ESD tests and evaluation purposes, it is also possible connect the module to the GSM/
UMTS/CDMA/GNSS test equipment through an SMA-to-Hirose-U.FL antenna cable and the
SMA antenna connectors of the DSB75 adapter.
A further option is to mount the evaluation module directly onto the DSB75 adapter’s 80-pin
board-to-board connector and to connect the test equipment as shown below.
