Hey All,
So I was wondering if anyone could tell me if the UBX Daughterboards
are configurable at all, and if so how? For example, looking at the
block diagram for the UBX 40 Daughterboard, it seems like some of the
clock parameters and filter parameters are that should be controllable
but I have not found any documentation on this. If someone can point
me in the right direction for this information it would be greatly
appreciated.
Best Regards,
Jerrid
The pre-ADC bandwidth of the UBX is fixed by the hardware
implementation--there are fixed hardware low-pass filters either side of
the ADC buffer amplifier.
In terms of clock, that *MIGHT* be possible, but it would require a fair
amount of surgery in the drivers--there's a daughterboard clock
that comes from the motherboard, which on some motherboards is
somewhat-reconfigurable, and on others is not.
What is your actual goal?
