MICRFXXX: User Manual for Development System, FW v.4
All I/O pins of the on-board micro are tristated. New in v.4: None of the MCU’s IOs are set as
output at power-on, if this combination is selected. That is: The User has full control, without
the MCU interacting at all (not programming the RF chip etc). The DIPs are tested before the
IOs are initiated.
Combination #6, Transmit a Random Pattern:
The board will enter transmit mode and transmit a random, Manchester-coded pattern (i.e.
without a DC component). Combination #6 can be used to test parameters like deviation and
transmit spectrum.
Suggestions for RF Testing:

1) Set one board to transmit a carrier. Use a spectrum analyser to observe the frequency
2) Set one board to receive mode and another to transmit 1010… Use an oscilloscope to
3) Set one board in receive-mode. Turn the other board off and use a signal generator to
spectrum. Repeat for transmit 1010…
observe the tx’ed and rx’ed data (Data I/O). Set tx’ed data as the trigger source.
input a 1010… pattern. Increase/Decrease the output power level from the signal
generator and observe LED1 and the rx’ed data. This can be used to test the
sensitivity: As long as the LED1 is on, the board is able to read a 1010… pattern.
Although a random pattern should be used in sensitivity measurements, this test gives
an indication of the possible detectable signal level. Note: Due to the long off-level
when an error is detected, this method will only give an indication of the “zero-error”
input level. For example, a BER (bit-error rate) of 10
