RF TESTING OF PAN4555
refer also to: freescale\documentation\13213EVKUG.pdf on the CD
ZigBee radio testing can be done using the "Test Tool" on a PC. Operation and some often
used functions are described below:
1. Install TestTool (from folder 132xxEVKCD on CD) on a PC with a free COM port.
2. Set the Testboard COM port to UART1 and connect it to the PC
3. If needed (for example for PER measurements within ZigBee Radio Test
of TestTool) connect the second Testboard (set to UART1 too) to a second
free COM port of the PC. If your PC does not provide enough serial ports,
a USB to COM converter cable could help.
4. This step is only required for reprogramming:
Flash program the embedded_bootloader_4555.s19 via the BDM and upload the
EVK_PTC_Demo_w_Embedded_Bootloader_V202_13213_NCB via the serial cable to
PAN4555 as described in 8.1.
5. Push RESET on the testboard and open TestTool\View\ZigBee Radio Test.
6. Open TestTool
7. Important: In section "SPI Registers" read modem control_b register address x07,
the result is 0x4ca0. This content means dual port mode as for 13213-NCB devices.
Change this setting by writing 0x5ca0 to register x07, enabling the MC13214 internal
Rx/Tx switch for single port operation.
Remark: in case of missing rf input/output while testing with TestTool readout this
register in order to check if it is still set to 0x5ca0 .
8. RF Testing Tx mode
" Set Continuous TX" with the result "Succeeded". PAN4555 is set to a continuous
unmodulated carrier for testing of wanted and unwanted (e.g. harmonics)
output power or carrier frequency accuracy.
The related settings are:
- "Channel", write for example 0x0b for the lowest frequency at 2405MHz or
0x1a for the highest frequency at 2480MHz.
- "Xtal Trim", the readout value is 0x7e. For series production this value might be
adjusted for PAN4555
- "Spi Register 12"
The default readout 0xbc sets PAN4555 to a power of approximately –3dBm.
In order to check the harmonics power, write 0xff for maximum power of
approximately +1dBm at the carrier frequency.
9. RF Testing Rx mode
The most important parameter for Rx mode is the sensitivity determined by
increasing the path loss between transmitter and receiver until the Packet Error Rate
inrceases from 0 to 1% (with 20 bytes payload according to the IEEE802.15.4
requirements). For detailed information on how to run PER measurements refer to
the freescale documentation.
Remark: Make shure that both Transmitter and Receiver are set to single
port mode as described under point 7.
