The PC software that controls the SmartRF TrxEB + EM is SmartRF Studio. Studio can be used
to perform several RF tests and measurements, e.g. to set up a CW signal and send/receive
packets.
The EB+EM can be of great help during the whole development cycle for a new RF product.
- Perform comparative studies. Compare results obtained with EB+EM with results from
your own system.
- Perform basic functional tests of your own hardware by connecting the radio on your
board to SmartRF TrxEB. SmartRF Studio can be used to exercise the radio.
- Verify your own software with known good RF hardware, by simply connecting your own
microcontroller to an EM via the EB. Test the send function by transmitting packets from
your SW and receive with another board using SmartRF Studio. Then transmit using
SmartRF Studio and receive with your own software.
- The SmartRF TrxEB can also be used as a debugger interface to the SoCs from IAR
Embedded Workbench for 8051.
- Develop code to the onboard MSP430 MCU and use the SmartRF TrxEB as a
standalone board without PC tools.
5.1 Absolute maximum ratings
The minimum and maximum operating supply voltages and absolute maximum ratings for the
active components onboard the SmartRF TrxEB are summarized in Table 2. Table 3 lists the
recommended operating temperature and storage temperature ratings. Please refer to the
respective component’s datasheet for further details.
