Hi Weixian,
I am also using a similar configuration. According to the ettus website,
I
got the following information, hope this helps. Both antennas can
transmit
and receive according to the information, but only one function
(transmit/receive) can be done at a time as the XCVR2450 is half-duplex.
XCVR 2450
The XCVR2450 has 2 quadrature frontends, one transmit, one receive.
Transmit
and Receive default to direct conversion but can be used in low IF mode
through lo_offset in uhd::tune_request_t
The XCVR2450 has a non-contiguous tuning range consisting of a high band
(4.9-6.0GHz) and a low band (2.4-2.5GHz).
Transmit Antennas: J1 or J2
Receive Antennas: J1 or J2
Frontend 0: Complex baseband signal for selected antenna
The XCVR2450 uses a common LO for both receive and transmit. Even though
the
API allows the RX and TX LOs to be individually set, a change of one LO
setting will be reflected in the other LO setting.
The XCVR2450 does not support full-duplex mode, attempting to operate in
full-duplex will result in transmit-only operation.
Transmit Gains:
VGA, Range: 0-30dB
BB, Range: 0-5dB
Receive Gains:
LNA, Range: 0-30.5dB
VGA, Range: 0-62dB
Bandwidths (Hz):
RX: 15M, 19M, 28M, 36M; (each +-0, 5, or 10%)
TX: 24M, 36M, 48M
Sensors:
lo_locked: boolean for LO lock state
rssi: float for rssi in dBm
