7.2.9. Packet Error Test
Using the PER Lab Mode users may evaluate the following:
1. PER Sensitivity
2. FIFO mode using predefined packet structures (see data sheet for further details)
3. Receiver modem parameters:
i. Automatic Frequency Control
ii. Blocking
iii. Selectivity
4. Connect the receiver's input to the signal generator's output.
7.2.9.1. Test Method
1. Set frequency, modulation type, data rate and deviation parameters on the RF signal generator.
2. Program a predefined packet into the generator using the format:
(preamble + sync_word(2DD4H) + data + CRC).
3. Set the signal generator to external single trigger mode.
4. The software development board (SDB) generates a trigger on test point P1.4, this should be connected to the
RF signal generator's external trigger input. The P1.4 pin will enable the signal generator to send one packet for
each trigger.
