– Key Features
• Low-reflection and low-loss design for accurate measurements in coaxial 50 Ω systems
• Individual calibration data stored for each measuring head and applied by compatible meters
• Microprocessor-controlled error correction in compatible instruments
• Automatic attenuation correction for connected measuring heads and external attenuators
• Relative measurement capabilities including difference, percentage difference, and ratio functions
• Tendency indication for maxima/minima adjustment and setting
• Dynamic range exceeding 90 dB enables measurements from microvolts to tens of volts
– Typical Applications
• Terminated power measurements in RF and microwave systems
• EMC test level measurement and verification
• In-line signal transmission characterization
• Voltage and power measurements in coaxial systems
• Component and subsystem performance assessment
– Compatibility & Integration
The URV5-Z2 integrates directly with Rohde & Schwarz URV5 series RF power meters and the URV55 millivoltmeter. Compatible instruments utilize stored calibration data to apply frequency-response and attenuation corrections automatically, maximizing measurement accuracy across the 9 kHz to 3 GHz operating range.
