The Agilent/Keysight 8413A is a phase-gain indicator plug-in meter display unit engineered to extend the measurement capabilities of the 8410A Network Analyzer. It measures and displays relative amplitude and phase difference between reference and test channel signals, delivering the gain and phase characterization data essential for component and system performance validation.
– Technical Specifications
• Amplitude Measurement: 80 dB range with selectable resolutions of 10 dB, 2.5 dB, 1 dB, and 0.25 dB
• Phase Measurement: ±180° range with selectable resolutions of 90°, 45°, 10°, and 1°
• Input Channels: Reference and test signal inputs for direct signal comparison
• Output Connectors: Linear phase and logarithmic amplitude outputs for oscilloscope or X-Y recorder display
– Key Features
• Front-panel pushbutton controls for function and range selection
• Calibrated meter presentation of swept frequency response versus reference signal
• Logarithmic amplitude scaling and linear phase scaling for standard graphical analysis
• Plug-in form factor for direct mainframe integration
– Typical Applications
The 8413A is suited for network analysis workflows requiring simultaneous phase and gain measurement, including filter characterization, amplifier performance validation, and impedance matching assessment across swept frequency ranges.
– Compatibility & Integration
This instrument is designed as a plug-in display module for the Agilent/Keysight 8410A Network Analyzer mainframe. The 8413A represents a legacy measurement solution documented in its Operating and Service Manual (part number 08413-90011, May 1974). This product is no longer manufactured or directly supported by Keysight.
