The Agilent/HP 8702B is a dual-domain network analyzer that characterizes optoelectronic and electrical components across 300 kHz to 3 GHz. It integrates electrical S-parameter analysis with optical lightwave measurements in a single platform, enabling hybrid-domain characterization essential for telecommunications and mixed-signal applications. The instrument delivers calibrated measurements for high-speed fiber optic systems, supporting transmission element analysis, electro-optical component testing, and electrical circuit characterization.
Technical Specifications
Frequency Range: 300 kHz to 3 GHz standard; Option 006 extends receiver operation to 6 GHz.
Optical Wavelengths: 850 nm, 1300 nm, and 1550 nm via external lightwave source and receiver modules.
Measurement Capabilities: S-parameter characterization of two-port electrical devices (forward/reverse transmission and reflection). Optical measurements include lasers, LED transmitters, photodiode receivers, optical fibers, connectors, splitters, couplers, and lenses. Time-domain analysis locates reflections and displays impulse/step responses without dead-zone limitations (Option 011 deletes this capability).
Electrical Measurements: Bandwidth, insertion loss/gain, phase, impedance, match, and group delay.
