4.4 RF Protocol
Command packets received by the DUT are “echoed” with the addition of an added byte that
contains the count of invalid bits for the received packet. Extra bytes in packets that are larger than
what the DUT can support are ignored. Commands other than “Echo Packet” are only “echoed” and
executed if the number of invalid bits are zero.
The RF command packets exchanged between the MTK test fixture and the MTK DUT contain two
bytes. The first byte contains the command type and the subsequent byte(s) contain the parameter
values as shown in
Table 4-1 .
Table 4-1. RF Commands
Note The “Transmit carrier” and “Transmit random pattern” test modes can be conditionally compiled
with the definition “MFG_TX_MODES”.
