Anritsu 37297B Vector Network Analyzer (40 MHz to 65 GHz)

The Anritsu 37297B is a vector network analyzer engineered for S-parameter characterization from 40 MHz to 65 GHz. It delivers accurate magnitude and phase measurements across complex RF testing scenarios, including antenna, filter, and broadband microwave device evaluation. The instrument integrates a synthesized swept source, auto-reversing S-parameter test set, and four-channel receiver into a compact bench-top unit optimized for both laboratory and production environments.

Technical Specifications

Frequency Range: 40 MHz to 65 GHz S-Parameter Measurements: Full magnitude and phase characterization with high-throughput, error-corrected sweep capability. Vector error correction supports 12-term, one-path two-port, reflection-only, and transmission response models. Calibration methods include SOLT, offset short, LRL/LRM, and TRM, with adapter removal capability for non-insertable devices. Source & Receiver: Integrated synthesized source with fast sweep performance. Four-channel receiver with specified dynamic range as the ratio of typical Port 1 power to noise floor. Display: 8.5-inch VGA color LCD with user-definable colors, eight simultaneous traces (two per channel), trace overlay, and independent marker control. Six markers support delta-reference mode and marker sweep. Limit-line testing, autoscale, and full annotation capabilities included. Calibration Support: LRL/LRM, GPC-7 error correction; 3.5 mm, N-type, K, and V connector models. Data I/O: Dual GPIB ports (IEEE 488.2) with ASCII, 32-bit, and 64-bit floating-point formats. Ethernet connectivity for high-speed transfers. Built-in mass storage with SCSI-2 hard disk and external drive support. Physical: 432 (W) × 267 (H) × 585 (D) mm; 29 kg. Power: 85 to 240 V, 48 to 63 Hz, 540 VA maximum. Operating temperature: 0° to 50°C. Storage: –40° to 75°C.
