The HP / Agilent 4195A is a high-performance, cost-effective, and intelligent analyzer with combined vector network and spectrum analysis capabilities. The frequency is covered from 10 Hz through 500 MHz with an excellent 0.001 Hz resolution for audio, baseband, HF, VHF, and IF applications. It directly measures amplitude ratio, phase, group delay, and spectrum level needed for characterizing linear/non-linear analog circuits or components used in communications, telecommunications, consumer electronics, and other equipment.

HP 4195A's excellent accuracy and resolution meet the severe measurement requirements for developing advanced equipment. A color display allows you to readily differentiate among multiple traces. Convenient softkey operation and marker functions make deriving device parameters quick and easy. Measurement results can be directly copied to printer or plotter without an external computer. Furthermore, the 4195A has internal user functions for computing and a self-controlling capability. User Program, User-Defined Function and User Math allow you to quickly customize the setups most suited to your application without using an external computer. A built-in 3 1/2-inch disk drive can save the instrument state, data, and user functions.
