Hi all,
I'm using USRP B210 and want to control both TX channels through message
port. My code of OOT module presented bellow
pmt::pmt_t d_txCommand;
d_txCommand = pmt::make_dict();
d_txCommand = pmt::dict_add(d_txCommand, pmt::mp("chan"),
pmt::mp(0));
d_txCommand = pmt::dict_add(d_txCommand, pmt::mp("lo_freq"),
pmt::mp(350e6));
d_txCommand = pmt::dict_add(d_txCommand, pmt::mp("gain"),
pmt::mp(30));
d_txCommand = pmt::dict_add(d_txCommand, pmt::mp("chan"),
pmt::mp(1));
d_txCommand = pmt::dict_add(d_txCommand, pmt::mp("lo_freq"),
pmt::mp(351e6));
d_txCommand = pmt::dict_add(d_txCommand, pmt::mp("gain"),
pmt::mp(30));
message_port_pub(PDU_PORT_ID, d_txCommand );
UHD sink block configured to use 2 chanels, MB0: Subdev Spec A:A A:B.
After running GRC file I see on spectrum analyser only one TX channel (the
last one -> 351e6 ). Is it possible to set both channels to work with
different frequencies? instead of lo_freq i tried to use dsp_freq, but
result was the same.
Best regards,
MK
