I am using a USRP1, and I'm trying to receive FM radio. I'm using a BasicRX
daughterboard with a 0-250MHz range. The USRP itself has a LO frequency of
64MHz. Does this limit my frequency range to 0-32MHz, or can I get into the
100MHz range by somehow multiplying that Local Oscillator frequency?
I get the following error:
-- Opening a USRP1 device...
-- Using FPGA clock rate of 64.000000MHz...
-- Tune Request: 102.900000 MHz
-- The RF LO does not support the requested frequency:
-- Requested LO Frequency: 102.900000 MHz
-- RF LO Result: 0.000000 MHz
-- Attempted to use the DSP to reach the requested frequency:
-- Desired DSP Frequency: -102.900000 MHz
-- DSP Result: 25.100000 MHz
-- Successfully tuned to -25.100000 MHz
