Hi,
Hope you're doing well. I am new here and new to the USRP API. Attached
is a setup to record signals at 380MHz and 2.4Ghz on two B200's. The aim
is to sync the devices using the 10Mhz and 1PPS provided from an
external source to both devices.
Using the python API to achieve this and here is a snippet used to test
multiple-usrp
In [1]: import uhd
In [2]: my_usrp = uhd.usrp.MultiUSRP("serial0=xxx310C,serial1=xxx311F")
In [3]: my_usrp.get_master_clock_rate(0)
Out[3]: 16000000.0
In [4]: my_usrp.get_master_clock_rate(1)
Traceback (most recent call last): File
"<ipython-input-4-aa48c097ad54>", line 1, in <module>
my_usrp.get_master_clock_rate(1)
RuntimeError: LookupError: IndexError: multi_usrp::mb_root(1) -
LookupError: IndexError: multi_usrp::mb_root(1) - path not found
Clearly the second device is not registered by the MultiUSRP method. I
found the C++ equivalent to this for the x series devices on the usrp
manual; which is:
uhd::device_addr_t
<https://files.ettus.com/manual/classuhd_1_1device__addr__t.html> args
<https://files.ettus.com/manual/namespaceprocess-lvbitx.html#a6105700373e342448ca66cbbdb9cf569>("addr0=192.168.10.2,addr1=192.168.20.2");
uhd::usrp::multi_usrp::sptr
<https://files.ettus.com/manual/classuhd_1_1usrp_1_1multi__usrp.html#a9d9112f5eac0b53a721f2a6c97021fc1>
usrp = uhd::usrp::multi_usrp::make
<https://files.ettus.com/manual/classuhd_1_1usrp_1_1multi__usrp.html#af0d3809a8f8dcd3c962ad5b9a0a6456c>(args
<https://files.ettus.com/manual/namespaceprocess-lvbitx.html#a6105700373e342448ca66cbbdb9cf569>);
Have these methods been exposed to the python API? If yes, a quick
example would be helpful.
Thanks very much.
