The Anritsu 37297C is a passive vector network analyzer spanning 22.5 MHz to 65 GHz, engineered for high-accuracy S-parameter measurements of passive devices. The instrument integrates a synthesized source, S-parameter test set, and tuned receiver into a single benchtop platform optimized for design validation and production testing.
Technical Specifications
• Frequency Range: 22.5 MHz to 65 GHz
• Measurement Capabilities: S-parameter and passive device measurements
• Data Points: Up to 1601 points or arbitrary N discrete points (2 ≤ N ≤ 1601); CW mode supports single-point selection
• Frequency Resolution: 1 Hz for narrow-band device measurements
• Measurement Update Rate: Less than 2 ms per point with 12-term error-corrected sweeps
• Dynamic Range: Receiver dynamic range specified as ratio of maximum Port 2 signal level to noise floor
– Key Features
• Fast 12-term error-corrected sweeps minimize measurement time while maintaining accuracy
• Built-in AutoCal® simplifies calibration workflows
• LRL/LRM calibration and adapter removal calibrations supported
• Six independent markers with delta-reference mode for flexible measurement analysis
• Marker sweep capability between any two frequencies without recalibration
• Two limit lines per trace for automated pass/fail testing with single or segmented thresholds
• Reference delay entry in time or distance; automatic electrical length compensation
• Separate trace memory per channel for post-measurement processing (subtraction, addition, multiplication, division)
– Typical Applications
• High-frequency component validation and characterization
• Passive filter, coupler, and transmission line measurements
• RF connector and adapter evaluation
• Design validation across microwave and millimeter-wave frequencies
– Compatibility & Integration
• IEEE 488.2 (GPIB) interface for high-speed data transfer and minimized collection times
• Secondary GPIB port for peripheral device control (printers, plotters, power meters, frequency synthesizers)
• Fast error-corrected sweeps combined with GPIB data transfer optimize measurement throughput
