• One HP 11512A shorting plug (Type-N male)
• Optional: three 10216A isolators, three 11576A 10:1 dividers, or two 11061A 10:1 dividers depending on configuration
– Typical Applications
Signal monitoring and impedance adaptation on 50 Ohm transmission lines. Precision termination for vector voltmeter measurements. High-frequency signal conditioning where probe-to-system impedance matching is critical.
– Compatibility & Integration
Primary compatibility with HP/Agilent vector voltmeters 8405A and 8508A. Operates with HP 85081B input modules (100 kHz to 1 GHz, high-impedance probe inputs) and HP 85082A input modules (300 kHz to 2 GHz, 50 Ohm Type-N inputs). Type-N connectors support integration with standard RF coaxial systems.
