WARPLab Specifications
Tx Signal Requirements
- 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.
- Lowest Frequency: 30 kHz. Radios filter DC.
- 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
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).
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).
- 40 MHz sampling frequency.
Tx/Rx I/Q Buffers
- Independent Tx/Rx I/Q Buffers.
- Buffers Persist between triggers.
- Samples are read from Tx I/Q Buffers to I/Q DACs at 40 MHz.
- Samples are written from I/Q ADCs to Rx I/Q buffers at 40MHz.
