Agilent / HP / Keysight 4195A

The Agilent 4195A unit is a vector Network/Spectrum Analyzer which offers full network and spectrum analysis at half the price can be operated in a frequency range of 10 Hz to 500 MHz .

The Agilent 4195A is a high performance, cost effective solution with an excellent 0.001 Hz resolution for audio, baseband, HF, VHF and IF applications.

The Agilent 4195A 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 HP 4195A has internal user functions for computing and self controlling capability. A color display allows differentiate between multiple traces.

The HP 4195A's excellent accuracy and resolution meets the severe measurement requirements for developing advanced equipment. 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. A built-in 3.5 inch disc drive is used to save the instrument state, data and user functions.

The HP 4195A has internal user functions for computing and self controlling capability. User Program, User Defined Function and User Math allow quickly customize the setups most suited to your application without using an external computer.

Network analysis functions of the 4195A include characterizing the gain/group delay ripple of filters and amplifiers. Spectrum analysis functions include the harmonic, intermodulation distortion of amplifiers or IF subsystems in communications and telecommunications.

S-parameters can also be measured by using 2 transmission/reflection test sets, without changing direction of the device.

The HP 4195A has three user functions for customizing operations for your applications without using an external computer. The User Program gives a one key solution for performing the aplication.

The user can program a sequence for measurement and marker control, computing, through printing a hard copying.

This function is very useful and improves efficiency for C/N (Carrier Noise ratio), THD (Total Harmonic Distortion) measurements or automatic device parameter extraction, such as an amplifier's gain, group delay, gain compression or harmonic distortion.

The User Math function helps you put the result in the format by using built-math operators and arithmetic functions.
