USRP limitations

GNU Radio
1

I’ve seen conflicting specifications for the receive bandwidth on the
USRP,
what is the absolute widest chunk of spectrum you can receive with the
BasicRX?

Also can the total bandwidth be split over a couple of ranges? or is it
always a single chunk?

Example, can I configure it to cover 1.8-2.0 MHZ, 3.5-4.0Mhz,
7.0-7.5MHz,
and 14.0-14.5MHz at the same time?

If you are using 16 bit complex samples, the USRP1 can send 8 MHz of RF
bandwidth to the host computer. If using 8 bit samples, you can do 16
MHz.

You can split it over 2 ranges, but the 2 ranges would need to be equal
in width.

7.0-7.5MHz, and 14.0-14.5MHz at the same time?

You really have 3 ranges here:

1.8 to 4.0
7-7.5
14-14.5

You could cover any 2 of those at once.

The LFRX is better for this than the BasicRX, BTW, since it has a 30 MHz
LPF and goes down to DC.
