I’m in the process to migrate our software currently using the old
libusrp2 to use the UHD.
My daughter board of reference is the WBX.
With the libusrp2 the gain range was [0, 31.5] while with UHD is [0,
I have noticed that now with UHD is possible to set (apart the overall
gain chain) the gain for the following elements:
WBX-PGA0 with a range [0.0, 31.5]
ADC-digital with a range [0.0, 6.0]
ADC-digital-fine with a range [0.0, 0.5]
this means that using the libusrp2 those two ADC gains were set to 6.0
and 0.5 giving then the user the ability
to change only the WBX-PGA0?
Even setting ADC-digital = 6.0, ADC-digital-fine = 0.5 and setting the
WBX-PGA0 to same value used with libusrp2
the result is not the same as in I’m losing something like 20 dB.
Is this expected ?
