• SL Cóndor II Console:
  Pulse Programmer and DDS: It is a digital pulse sequencer, which is programmed by a conventional personal computer by
  means the conventional bidirectional printer interface (USB2 available).
  The pulse programmer is related to the DDS (Direct Digital Synthesizer) with double sinusoidal output.
  The pulse programmer uses the same clock of the DDS.
  The frequency and the phase of the generated signal by the DDS's synthesizer are selected digitally by the Pulse Programmer.
  Technical Overview of the Pulse Programmer:
  Model: PP2
  Time Base of pulse and valley lengths: 20 ns
  Outputs: 16 individual programmable channels.
  Maximum time of pulse: 215 s.
  Minimum time of pulse: 480 ns.
  Technical Overview of the DDS:
  Main Clock: 50 MHz
  Outputs: Two sinusoidal.
  Output filters: passive, seven poles.
  Output maximum frequency: 20 MHz
  Output minimum frequency: 0.012 Hz.
  Frequency registers: four registers of frequency of 32 bits selected by software or digitally from the PP2.
  Phase registers: eight registers of 12 bits selected by software or digitally from the Pp2.
  System of digitalization of the signal:
  Analogical to Digital Converter: Two 12 bits independent Channels.
  Interface for the signal transference: via parallel bidirectional port. Optional: via USB2.
