Agilent/Keysight 85330A

The Agilent/Keysight 85330A is a Multiple Channel Controller engineered to extend automated measurement systems based on the 8530A Microwave Receiver. It delivers high-speed, multi-channel measurement capability by orchestrating high-isolation solid-state microwave switch modules, sequencing measurement functions, and synchronizing data acquisition across multiple channels and frequencies. The controller enables rapid throughput and efficient operation in complex test setups involving antenna characterization, radar cross-section (RCS) measurements, and communication system analysis.

• Frequency Range: 45 MHz to 26.5 GHz (extensions to 110 GHz)
• Measurement Speed: Up to 5,000 data points per second
• Data Buffer Capacity: 100,000 measurement points
• Phase Accuracy: Better than 0.5° over 70 dB range
• Magnitude Accuracy: Better than 0.06 dB over 70 dB range

– Key Features

• Manages multiple measurement channels with synchronized sequencing
• Supports Angle Domain, Frequency Domain, and Time Domain measurements
• High sensitivity and wide dynamic range inherited from 8530A receiver integration
• Compatible with high-isolation solid-state switch modules
• Performance comparable to the 8510C Network Analyzer

– Typical Applications

• Antenna performance characterization across angle and frequency domains
• Radar cross-section (RCS) measurements in time domain
• Multi-channel automated measurement systems requiring rapid data acquisition
• Communication system and radar testing environments

– Compatibility & Integration

The 85330A integrates with the Agilent/Keysight 8530A Microwave Receiver and has been validated with switch modules including the 85331A and 85332A. The controller coordinates measurement sequencing to maximize data throughput while maintaining measurement accuracy across the receiver’s full frequency and dynamic range specifications.
