Session Notes 

As RF and microwave testing pushes to higher frequencies and faster digital speeds, maintaining measurement accuracy becomes increasingly difficult. Many testing environments now operate outside of tightly controlled laboratories, such as production racks, flight lines, and field test setups, where cables are frequently moved or reconfigured. 

AccuPhase was designed specifically to address these evolving challenges by minimizing measurement variation caused by cable movement and environmental conditions. The result is a cable assembly that helps maintain calibration and ensures consistent measurement performance even after repeated handling.  

Key Performance Benefits 

AccuPhase assemblies provide several advantages for test engineers and production environments: 

  • Phase and amplitude stability – Enables repeatable measurements with fewer recalibrations 
  • Flexible and lightweight construction – Simplifies routing on crowded test benches and reduces stress on connectors and devices under test 
  • Rugged durability – Engineered to withstand over 200,000 flex cycles for long service life 
  • Effective EMI shielding – Maintains measurement accuracy in dense test environments 

Together, these features help improve test throughput while lowering the total cost of ownership compared to frequently replaced standard test leads.  

Typical Applications 

AccuPhase test assemblies support a wide range of high-frequency testing scenarios, including: 

  • Vector Network Analyzer (VNA) port extensions and test-port adapters 
  • Automated production test systems 
  • High-volume manufacturing test racks 
  • Antenna ranges and anechoic chambers 
  • Flight-line and field testing environments 
  • R&D laboratories across aerospace, defense, and telecom industries 

These applications benefit from the cable’s ability to maintain stable electrical performance even when flexed or repositioned during testing.  

Product Configurations and Availability 

The AccuPhase family includes multiple frequency options designed to support different testing needs: 

  • AccuPhase26.5 – Available 
  • AccuPhase70 – Available 
  • AccuPhase40 – Planned for release in Q2 2026 
  • AccuPhase50 – Planned for release in Q2 2026 
  • AccuPhase110 – Future roadmap product 

A range of precision connectors are available depending on frequency band and application requirements, including 1.85 mm, 3.5 mm, SMA, N, and TNC interfaces.
