Set Multi-Antenna Search Configuration
Option = 0x02 allows the order antennas will be used during a multi-antenna search with
to be specified. The multi-antenna search allows mixing of
monostatic and bistatic configurations and ports can be duplicated in the search list if it is
desirable to return to some antennas more often than others. The number of antennas
available for use and the specific physical to logical port mapping is based on the
GPIO
as Antenna Switch
settings specified in
.
Set Logical Antennas Command Fields (Option = 0x02)
Note
If a search configuration is not specified the default is a single bistatic
antenna on TX=1/RX=2.
Set Antenna’s Power and Settling Time
Option =0x03 and 0x04 allows the power and settling time (only option=0x04) for each
logical antenna to be set. The order the antennas settings are defined does not affect
search order.
Note
Settling time
is the time between once the control lines switch to the next
antenna setting and RF turns on for operations on that port. This allows time
for external multiplexer’s to fully switch to the new port before a signal is
sent, if necessary.
Default value is 0

TX/RX Logical
Antenna
[2 bytes]
One or multiple 2 byte pairs indicating the logical TX and RX
antennas to use. The order specified indicates the order
antennas will be used in a multi-antenna search.
Note:
Monostatic and bistatic logical antennas can be mixed in
the same search list and entries can be repeated.
Note:
Repeat the TX/RX Logical Antenna field for each logical antenna being configured for the
search list in the desired search order.
