AT86RF212
The AT86RF212 offers a Continuous Transmission Test Mode to support application /
production tests as well as certification tests. Using this test mode, the radio transceiver
transmits continuously a previously transferred frame (PRBS mode) or a continuous
wave signal (CW mode).
In CW mode, one of four different signal frequencies per channel can be transmitted:
• f
• f
• f
• f
F
possible to transmit a RF signal directly on the channel center frequency.
Data in the Frame Buffer must contain a valid PHR (see section 6.1) followed by PSDU
data. After transmission of two non-PSDU symbols, PSDU data is repeated
continuously.
Before enabling Continuous Transmission Test Mode, register configurations shall be
done as follows:
• TX channel setting (optional)
• TX output power setting (optional)
• Mode selection: PRBS or CW mode. PRBS mode further requires selection of a
Register write accesses to register 0x36 and 0x1C enable the Continuous Transmission
Test Mode. The transmission is started by enabling the PLL (TRX_CMD = PLL_ON)
and writing the TX_START command to register 0x02.
The detailed programming sequence is shown in Table A-1. The column R/W informs
about writing (W) or reading (R) a register or the Frame Buffer.
