DC offset removal

GNU Radio

Hi all

Is it possible to disable the automatic DC offset removal control loop
in
the FPGA to measure DC? In old posts I found the function
“set_dc_offset_cl_enable”. But if I try that, this function can not be
found.

I use a USRP N210 with a LFRX board.

my code:
…
self.uhd_usrp_source_0 = uhd.usrp_source(
device_addr="",
stream_args=uhd.stream_args(
cpu_format=“fc32”,
channels=range(1),
),
)
…
self.uhd_usrp_source_0.set_dc_offset_cl_enable(0x0,0xF)
…

Any help will be appreciated.

Thanks
Michael
