CC2430
Radio : Transmitter Test Modes
pseudorandom bit sequence for bit error
Another option to generate a modulated
spectrum is to fill the TXFIFO with pseudo-
random data and set MDMCTRL1L.TX_MODEto
2. CC2430 will then transmit data from the FIFO
disregarding a TXFIFO underflow. The length
of the transmitted data sequence is then 1024
bits (128 bytes).
testing. Please note that CC2430 requires
symbol
synchronization,
not
only
bit
synchronization, for correct reception. Packet
error rate is therefore a better measurement
for the true RF performance.
A plot of the modulated spectrum from CC2430
is shown in Figure 49. Note that to find the
output power from the modulated spectrum,
the RBW must be set to 3 MHz or higher.
