The Agilent/Keysight 85134H is a flexible test port cable assembly engineered for network analyzer applications. It connects the analyzer test port to devices under test via a 2.4 mm female to 3.5 mm male connector configuration. The 62.9 cm cable delivers stable, repeatable measurements across DC to 26.5 GHz with controlled insertion loss and excellent return loss performance.
Technical Specifications
• Length: 62.9 cm (24.75 inches)
• Connector Configuration: 2.4 mm female to 3.5 mm male
• Frequency Range: DC to 26.5 GHz
• Return Loss: ≥16 dB
• Insertion Loss (Test Port Connector): 0.31 × √f + 0.2 dB (f in GHz)
• Insertion Loss (Device Connector): 1.8 dB maximum at 26.5 GHz – Key Features • Phase Stability: Characterized at 90-degree bend with 2.5-inch radius – Amplitude Stability: <0.12 dB – Phase Stability: <0.13° × f + 0.5° (f in GHz)
• Connector Integrity: The 2.4 mm female connector is purpose-designed for network analyzer test ports and is not compatible with standard male connectors
• 3.5 mm Male Connector: Standard configuration for DUT connection – Typical Applications • Network analyzer test port interconnection
• Device characterization and S-parameter measurement
• High-frequency component testing to 26.5 GHz – Compatibility & Integration Designed exclusively for network analyzer test ports equipped with 2.4 mm female connectors. The non-standard 2.4 mm female end ensures proper mating with compatible analyzer ports while preventing connection to standard RF equipment.
