– Key Features
• High power handling capability: measures devices with up to 20 W (+43 dBm) CW output when internal step attenuators and isolator are installed
• Input power protection: step attenuators provide +17 dBm threshold; exceeding this requires equivalent attenuation
• Connector torque limit: 90 N-cm maximum to protect test ports and connected adapters
– Compatibility & Integration
Designed for integration with the HP 8510 network analyzer platform.
