The Agilent/Keysight 8755B is a system detector for scalar network analyzers, designed to detect and process RF signals across microwave frequencies. This component operates as a signal detector within the 8755 Series Swept Amplitude Analyzer ecosystem, providing accurate measurement of both modulated and unmodulated microwave signals for display on compatible analyzers.
Technical Specifications
• Frequency Range: 10 MHz to 26.5 GHz
• Input Impedance: 50 ohms
• Connector Type: N (male)
• Maximum Input Power: +20 dBm (100 mW)
• Shipping Weight: 3 lb
– Key Features
• Detects AC (modulated) and DC (unmodulated) microwave signals
• AC Mode Dynamic Range: +16 dBm to −55 dBm
• DC Mode Dynamic Range: +16 dBm to −50 dBm
• Power Measurement Range: +16 dBm to −60 dBm
• Wide frequency coverage from 10 MHz through 26.5 GHz enables testing across L-band through Ka-band applications
– Typical Applications
• Integration with scalar network analyzers for gain/loss measurement
• RF signal detection and power monitoring
• Swept amplitude analysis in microwave test systems
• Legacy system maintenance and expansion
– Compatibility & Integration
The 8755B pairs with Agilent/Keysight 8755, 8756, and 8757 Series Scalar Network Analyzers. Note that the Agilent 85025B detector, designed for the 8757D, is incompatible with 8756 and 8755 models. Proper detector selection ensures correct signal path integration within the host analyzer architecture.
