Performance Demonstrations of Omega – HZx Interface with 2, 3 or 4 Wire Front Connection
In the figures below, we present measurement outcomes obtained through Omega Advanced Modular Frequency Analyzer with HZx Dielectric High Impedance Interface 2, 3 or 4 Wire Front Connection with FR-EX3 and Enhanced Limitation.
All measurements are done with:
• 100cm BNC Cables between analyzer and Interface
• 25cm BNC Cables between sample holder and analyzer
• Sampling time 0.5s or 1 Cycle.
• Auto Referencing mode enabled
