Agilent/Keysight 8512A

The Agilent/Keysight 8512A is a reflection/transmission test set engineered for the HP 8510 network analyzer system. It enables S-parameter measurements of two-port devices across 0.400 GHz to 18 GHz, performing reflection (S11) and transmission (S21) analysis without requiring physical DUT reversal. The test set integrates three RF-to-IF converters for signal path access and uses NMD-3.5 mm test port connectors.

– Technical Specifications

• Frequency Range: 0.400 GHz to 18 GHz
• Test Port Connectors: NMD-3.5 mm with center pin recession of 0.005 mm to 0.056 mm (0.0002 in. to 0.0022 in.)
• Recommended Test Port Cable: HP 85132C 7 mm test port return cable (DC to 18 GHz)
• RF-to-IF Conversion: Three converters for reflection and transmission measurements
• Step Attenuators: Not included
• Bias Tees: Not included

– Key Features

• Dedicated two-port S-parameter measurement capability
• Reflection and transmission analysis without DUT reversal
• NIST-traceable calibration
• Direct integration with HP 8510 analyzer systems
• Three independent RF-to-IF conversion paths

– System Integration

The 8512A operates as an integral component of the HP 8510 measurement system. When paired with the HP 8510B network analyzer, the system delivers S-parameter measurements across the test set’s operating range. Electrical specifications and configuration details are defined in the HP 8510B System Manual and HP 8510A manual set (volume 1, General Information section).

– Typical Applications

The test set supports device characterization in research, development, and manufacturing environments where reflection and transmission analysis of electronic components and sub-assemblies is required.

– Compatibility & Integration

Designed exclusively for HP 8510 network analyzer systems. Service centers perform calibration to manufacturer specifications with NIST traceability. The HP 85132C 7 mm test port return cable (two 7 mm connectors, DC to 18 GHz) is the standard accessory for port connection.
