Key Features

• Two independent measurement channels for simultaneous parameter capture


• Integrated synthesized source with fine 1 Hz resolution across the full band


• Three-input receiver section enabling flexible device configurations


• Time-domain analysis capability (Option 010): low-pass TDR mode and simulated transient response


• Marker functions for peak search, minimum detection, and target-value location


• Full programmability via HP-IB (Hewlett-Packard Interface-Bus)


• Built-in calibration enhancement for sustained measurement accuracy

Typical Applications Linear characterization of passive and active components, PCB transmission lines, filters, amplifiers, and microwave assemblies. Lab and production environments benefit from measurement speeds and repeatability across the VHF through microwave bands.

Compatibility & Integration Works with S-Parameter test sets (HP 85046A/B, HP 85047A) for extended device access. Precision 7 mm test ports and Type-N connectors interface with standard test cables. Accepts external control through HP-IB interface for automated test sequences and data logging.
