Hi,
Use usrp_fft.py with decimation rate of 8. In this case, you can see 8MHz of
spectrum. Also, you can use 8 bit data transfer with decimation rate of 4 to
look at 16 MHz wide spectrum.

Hi,
USRP can transfer data at maximum of 32MB/s using its USB2. When the data
are 16 bit wide (16bit I and 16 bit Q) then maximum complex transfered data
will be 8 Msps which gives idealy maximum 8 MHz bandwidth. However, if we

I suggest you run partition magic and divide your hard disk into a new

1) What is your recording system (PC specifications)?.
2) How fast your hard drive can read/write data? because working with 8MHz
means that your hard drive must be able to sustain writing 32MByte/sec?

When you use 8 bit data transfer (decimation =4) you will get the 16MHz

Outside this range, the tune function is working fine.

I want to draw your attention to this remake:
When using std_4rx_0tx.rbf FPGA file, the 4 FPGA DDCs does not have low
