If I want to apply the output (50 ohm) from a function generator
directly to the BasicRX inputs, what is the allowed voltage range
can be applied:
- Without damaging anything?
3V pk-pk should be safe, since it won’t exceed the 3.3V supply voltage
Thanks. Does this mean that the signals need to be DC offset so as never
to go below ground?
- Without exceeding the range of the ADC?
The full-scale range of the ADC is 2 V pk-pk
Is there an offset, or is it 0V to 2V?
Surely this kind of stuff is documented someplace. But where? I
find anything on the Ettus website that has it.
Is there someplace where this is documented?
Thanks a lot.
