The need for an external sound card to provide the A/D and D/A conversions of the I/Q signals was a requirement only for first generation software defined radios, such as the SDR-1000 other SDRs that utilize the SDR-1000 architecture. All second generation and beyond SDRs from FlexRadio Systems, such as the FLEX-3000 do not require a sound card of any kind to operate. The A/D and D/A converters are integrated into the radio hardware.
