Keysight / Agilent 8720D Network Analyzer

The Keysight / Agilent 8720D Network Analyzer is engineered for precision and efficiency in the field of microwave testing, delivering a broad frequency range of 50 MHz to 20 GHz. With a drastically enhanced processor speed—seven times faster than its predecessors—this device ensures rapid and reliable measurements, making it an ideal choice for R&D, manufacturing, and quality assurance applications.

Key Features

Fast Sweeping Synthesized Source: Features a built-in fast sweeping synthesized source, providing stable and accurate readings with a typical frequency accuracy of 10 ppm.

Dynamic Range: Equipped with tuned receivers that deliver an impressive dynamic range of up to 105 dB.

Integrated S-Parameter Test Set: The integrated solid-state switching S-Parameter test set facilitates comprehensive testing options in various environments, including coaxial, waveguide, in-fixture, and on-wafer.

Advanced Measurement Capabilities

The 8720D allows for fast testing of both linear and nonlinear microwave devices. Two independent channels enable simultaneous measurement and display of all four S-Parameters. Users can view reflection and transmission measurements in various formats, including magnitude, phase, group delay, SWR, and Smith Charts. The built-in vector accuracy enhancement guarantees superior error-corrected accuracy while accommodating a range of coaxial connectors.

Powerful Testing for Active Devices

With a maximum output of +5 dBm at the test ports, the HP 8720D provides ample power for testing amplifiers. For smaller, sensitive signal devices, it includes a built-in step attenuator that can adjust power levels down to -70 dBm. The power meter calibration function allows for precise control over absolute power levels throughout the system, making it easy to analyze gain-compression characteristics of active components.

Intuitive User Experience

Designed for user-friendly operation, this network analyzer incorporates features like a swept-list mode to accelerate measurement times by targeting specific frequencies. The fast two-port tuning mode streamlines 12-term error correction, while the automated test sequencing function enables users to create and execute test sequences effortlessly. The device also supports limit testing for consistent pass/fail outcomes, provides up to five markers per channel, and offers a variety of connectivity options with serial and parallel interfaces.

Enhanced Productivity Features

The Keysight / Agilent 8720D is equipped with 2 MB of internal non-volatile memory, capable of storing up to 31 test configurations, and features a VGA compatible output for larger external monitors. With independent IF bandwidths and power levels configurable across frequency ranges, it is the perfect solution for seamless microwave testing.
