Agilent / Keysight U3022AM04 26.5 GHz, 6-Port Mechanical Test Set

The Keysight U3022AM04 is a 6-port mechanical test set engineered for RF and microwave characterization across 300 kHz to 26.5 GHz. This multiport instrument delivers precision measurements and calibration capabilities essential for network analysis of complex devices in demanding RF environments. With six high-quality ports and mechanical construction optimized for repeatability, it is a front-end solution for extended multiport measurement systems.

Technical Specifications

• Frequency Range: 300 kHz – 26.5 GHz


• Port Count: 6 ports


• Weight: 25 lbs


• Operating Humidity: Up to 80% relative humidity at 31 °C, decreasing linearly to 50% relative humidity at 40 °C


• Installation Category: II


• Pollution Degree: 2

Key Features

• High-precision connectors support repeatable multiport measurements across the full operating range


• Mechanical design engineered for stable performance in temperature-controlled environments


• Requires ambient temperature maintenance within ± 1 °C of calibration temperature for accuracy-enhanced measurements


• Cabinet installation demands unrestricted convection; forced convection required when total power dissipation exceeds 800 watts


• RF power levels must be maintained 3 dB below maximum to prevent measurement instability and device damage

Typical Applications

• Multiport device characterization and network analysis


• RF and microwave component testing and calibration


• S-parameter and transmission measurements


• System-level validation of passive multiport networks

Compatibility & Integration The U3022AM04 integrates with Keysight PNA, PNA-L, or PNA-X network analyzers to create complete 8- or 10-port full crossbar measurement systems. When combined with an analyzer, both instruments must maintain ambient temperature within ± 1 °C of the temperature at calibration for accuracy-enhanced operation.
