Agilent / HP 4195A

The Agilent HP 4195A is a high performance, cost effective and intelligent analyzer with combined vector network and spectrum analysis capabilities.  The frequency is covered from 10Hz throughout 500MHz with an excellent 0.001Hz 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.

The 4195A's excellent accuracy and resolution meets the severe measurement requirements for developing advanced equipment.  A color display allows you to readily differentiate between 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 self controlling capability.  User program, User Defined Function and User Math allows you to quickly customize the setups most suited to your application without using an external computer.  A built-in 3.5 inch disc drive can save the instrument state, data and user functions.
