USRP™ X300 and USRP™ X310 SDRs Frequently Asked Questions
- What is the bandwidth of the USRP X300/X310
The ADC rate on each analog RX channel is 200 MS/s quadrature, which provides a theoretical analog bandwidth of approximately 80% of the Nyquist bandwidth of +/- 100 MHz (+/- 80 MHz around the center frequency). The resulting maximum theoretical analog bandwidth is 160 MHz. The actual analog bandwidth may be reduced due the RF daughterboard selected.
RF Daughterboard Bandwidths: See the daughterboard specifications [link]
FPGA Processing Bandwidth: Up to 200 MS/s quadrature.
Host Bandwidth: Up to 200 MS/s quadrature, dependent on selected interface
