HP / Agilent 35678A Type-N Calibration Kit

The HP/Agilent 35678A Type-N Calibration Kit is a 50 Ω precision calibration standard designed for vector network analyzers and S-parameter test sets operating with Type-N connectors. This kit delivers the calibration standards required to establish measurement accuracy across RF and microwave test setups, with all measurements traceable to United States National Bureau of Standards and ISO member calibration facilities.

## Technical Specifications

• **Connector Type:** Type-N (50 Ω)
• **Impedance:** 50 Ω
• **Frequency Range:** DC to 200 MHz
• **SWR Performance:** 1.005 maximum (DC to 200 MHz) for specified terminations

## Key Features

The kit includes shorting plugs and jacks (N-male and N-female), straight coaxial adapters for both genders, and matched 50 Ω terminations in male and female Type-N configurations. All standards are designed for high-precision operation in laboratory and field environments. The kit ships in a mahogany carrying case with protective foam padding and includes complete operating documentation.

National standards traceability ensures that calibration results maintain metrological integrity across your measurement chain.

## Typical Applications

• Removal of systematic errors in network analysis (directivity, port match, frequency tracking)
• Verification and maintenance of measurement system accuracy
• Self-calibration routines for automatic network analyzers
• RF and microwave test setup calibration
• Minimization of measurement uncertainty in S-parameter characterization

## Compatibility & Integration

The 35678A is specified for use with HP/Agilent 3577A and 3577B Network Analyzers. It integrates with the 35677A and 35677B S-Parameter Test Sets, as well as the 35676A and 35676B Reflection/Transmission Test Kits, enabling plug-and-play calibration workflows across compatible instrument families.
