SPECIFICATION

  • 2 independent autocorrelators.
  • Each autocorrelator will independently provide:
    • Selectable bandwidths: 2GHz1, 1GHz, 512MHz, 256MHz, 128MHz, 64MHz.
    • Input frequencies: At 2GHz and 1GHz BW, baseband signal. At other bandwidths – yet to be determined.
    • Nyquist sampling, 2 bits, 3 levels, at all bandwidths.
    • Number of frequency channels: 2048 maximum at all bandwidths.
    • Synchronous accumulation, for frequency and beam switching and corresponding outputs for driving receiver/LO switches.
  • The correlator will have its own clock generator, which will be locked to a local standard frequency at 5 or 10MHz.
  • Timing within the correlator will come from the standard ATNF distributed clock/event generator system.
  • A correlator control computer will supervise all aspects of the control, monitoring and data taking of the correlator.
  • Power input will be either 115 or 220V at 50 or 60 Hz. Power requirements, yet to be determined.
  • The correlator will be contained within an RF shielded rack.
