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.
