I just get my "new" DSO1000B and after I update src/hardware/rigol-ds/api.c to support the name (the A and B are the same F/W ) I'm getting issues on using it :

looking at :
https://www.keysight.com/upload/cmc_upload/All/1000_series_prog_guide.pdf
the oscilloscopes send 10X and not 10 (see page 96 ) and in line 876:
src/hardware/rigol-ds/protocol.c 
its (so looking for float:
res = sr_scpi_get_float(sdi->conn, cmd, &devc->attenuation[i]);
i did test using :
res = sr_scpi_get_string(sdi->conn, cmd, &devc->attenuation[i]);
but that just trasform it to float 
looking at Agilent MSO7000A i see its send 10 and not 10X so the DSO1000 need to be "fix"
