Control Processor Series CP2021

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 payloads
– 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
