Agilent / HP 8720E
Vector Network Analyzer 50MHz to 20GHz
Description
The Agilent/HP 8720E vector network analyzer integrates a microwave source, tuned receiver, and transmission/reflection or S parameter test set into a single, cost-effective instrument.
To complete a microwave measurement system, select the desired network analyzer options, test port cables, and calibration kits.
Each display channel of the 8720E has five independent markers that can be displayed simultaneously. Twenty independent markers can be displayed in the 4-channel display mode when markers are uncoupled.
The 8720E provides display in Cartesian, Smith chart, and Polar formats. The maximum delay is limited to measuring no more than 180° of phase change within the minimum aperture.
Up to 31 instrument states can be stored internally and recalled via the SAVE/RECALL menu. Instrument states include all control settings, active limit lines, active list frequency tables, memory trace data, active calibration coefficients, and custom display titles. Storage is in non-volatile memory.
Data, instrument states, user graphics, data plots, and test sequences can be stored on internal floppy disk in MS-DOS or Agilent’s standard LIF formats.
The tuned receiver of the 8720E tunes the receiver for a synthesized CW input signal at a precisely specified frequency. The time bases of the external RF source or sources must be tied to the external reference input of the network analyzer (rear panel BNC).
The GPIB connector at the rear panel of 8720E allows communication with compatible devices including external controllers, printers, plotters, disk drives, and power meters. Parallel port connector is used with parallel (or Centronics interface) peripherals such as printers and plotters.
RS-232 connector is used with serial peripherals such as printers and plotters. The mini-DIN connector is used for the optional AT compatible keyboard for titles and remote front-panel operation.
A wide range of accessories support the Agilent 8720E family of network analyzers, including calibration kits, verification kits, cables, and adapters in 7 mm, 3.5 mm, 7-16, Type-N, and 2.4 mm coax and in the standard waveguide bands. The standards used in the 3.5 mm, Type-N, and 2.4 mm calibration and verification kits use precision slotless connectors (PSC-3.5, PSC-N, and PSC-2.4).
