Question regarding Basic Tx/Rx Boards

GNU Radio
1

Hi.

I have two questions:

1.) Is there any difference between the Basic Tx/Rx daughter boards that
were shipped with rev3 usrp board and rev4 usrp board?

2.) What is the functionality of .ihx (firmware file)? How is it
different
from the fpga (.rbf) file?

Thanks.

No, the circuitry is the same. Some very early boards had a slightly
different silkscreen, but that is all.

2.) What is the functionality of .ihx (firmware file)? How is it different

The ihx file is compiled firmware for the 8051 in the FX2 USB chip.
