I am student (not a starving student) who started researching with GNU
Software last month. This week, I am trying to implement an I/Q Lab
the USRP2 board.
What I mean is that I would like to create my own IP (for example a
and to program it into the FPGA. Then, I would like to generate pair of
signals (I and Q), connect them to the FPGA and receive the exit in an
oscilloscope. This is the main idea.
I read that I need the BasicRx/BasicTx or LFRX/LFTX daughterboards
on the frequency. Related to those daughterboards, I have some questions
could not answer yet and I would appreciate if you could help me:
- What is the purpose of the access to the 16 bits of high-speed
- What is the purpose of the low-speed ADC’s and DAC’s?
- What is the purpose of the SPI and I2C buses? It is possible to
some parameters of the FPGA design using the I2C connected to a PC?
the filter example, to change on the fly, the value of the
It would be great if you could tell me if there some manual or datasheet
about them. I found this:
And also this schematic:
but I am looking for the meaning of different pins and I am not so good
Thank you so much.
