| | 3 | === Tx Signal Requirements === |
| | 4 | * Amplitude of real part (In-Phase signal: I) in [-1,1] and amplitude of imaginary part (Quadrature signal: Q) in [-1,1]. I/Q signals on transmitter path are represented in the FPGA using Fixed Point 16_15. |
| | 5 | * Lowest Frequency: 30 kHz. Radios filter DC. |
| | 6 | * Highest Frequency: Depends on the Tx/Rx Low Pas Filter (LPF) Corner Frequency Setting. By default, Tx and Rx LPF are set to nominal mode. Possible Tx/Rx LPF settings are the follwoing |
| | 7 | Tx LPF corner frequency: Mode 0: Undefined, Mode 1: 12 MHz (Nominal Mode), Mode 2: 18 MHz (Turbo Mode 1), Mode 3: 24 MHz (Turbo Mode 2). |
| | 8 | [[BR]]Rx LPF corner frequency: Mode 0: 7.5 MHz, Mode 1: 9.5 MHz (Nominal Mode), Mode 2: 14 MHz (Turbo Mode 1), Mode 3: 18 MHz (Turbo Mode 2). |
| | 9 | * 40 MHz sampling frequency. |
| | 10 | |
| | 11 | === Tx/Rx I/Q Buffers === |
| | 12 | * Independent Tx/Rx I/Q Buffers. |
| | 13 | * Buffers Persist between triggers. |
| | 14 | * Samples are read from Tx I/Q Buffers to I/Q DACs at 40 MHz. |
| | 15 | * Samples are written from I/Q ADCs to Rx I/Q buffers at 40MHz. |
