Testing CreataLink2 XT Hardware Integrator’s Guide
Hardware Integration
• Antenna performance—Ensure the integrated antenna system meets the
required ERP specifications, VSWR specifications, and antenna propagation
patterns.
• ESD requirements—Ensure the host design protects the data transceiver from
electrostatic discharge.
• RF Re-radiation—Ensure the host does not allow spurious emissions in excess
of 60 dBc, caused by carrier re-radiation.
Desense and EMI
Any device with which the data transceiver integrates can generate enough EMI to
reduce the ability of the data transceiver to receive at certain frequencies.
The ability to turn on and turn off various circuits in the data receiving device
provides identification and analysis of the components that cause desense. This
approach to desense troubleshooting can shorten the integration effort. It is critical
that you consider the data transceiver shielding early in the design phase.
