Control Processor Model CP2021 controls all Flann programmable products including Rotary Vane Attenuators, Phase Changers and Polarizers.

Applications:

  • Automated production testing of microwave radios and satellite communication payload
    • Fade margin testing
    • Gain control
    • Bit Error Rate
  • Automated test and measurement systems
  • Remote control systems
  • Extraordinary resolution & settability at low attenuations

Attenuator Performance

  • 0 dB to 60 dB in less than 1.1 seconds
  • 0 dB to 120 dB in less than 2.2 seconds
    (2 attenuators connected in series)
  • 3 GHz to 140 GHz (in waveguide bands)
  • IEEE488.2 GPIB Bus and USB Control
    Will position to:
    0.01 dB between 0 dB & 21 dB
    0.02 dB between 21 dB & 30 dB
    0.05 dB between 30 dB & 48 dB
    0.1 dB between 48 dB & 60 dB

Phase Changer Performance

  • Continuous phase change in either forward or reverse direction
  • Smallest phase change increment is 0.2°
  • Rate of phase change is 1480 degrees per second.

Controlling Cable Requirements

  • A conversion cable is required when driving
  • Series 610
  • Series 611
  • Series 660 instrumentation using a CP2021

 

  • Unchallenged accuracy, reliability and repeatability
  • Built in self test and diagnostics
  • Control of 1 or 2 attenuators giving a possible attenuation range of 120 dB
  • Universal line input, automatically switched between 115 V and 230 V
  • Steps mode operation allows greater control over instrument positioning
  • Recognises any Flann programmable products when connected to the drive ports
  • Extended drive cable capability to 20 meters, with extended (slower drive) up to 50 meters
  • HS488 High speed GPIB capability – up to 8 Mb/s
  • Ability to learn previous CP92 series GPIB commands
