USER FUNCTIONS
User Math Puts the result in the form needed for your application by using built-in math operators, arithmetic functions and editing capability.
User Defined Function Provides one-key solution for a specific application without an external computer.  6 user functions can be created and soft-keys can be labeled as you like.
User Program (Auto Sequence Program) Allows to program the control or measurement, analysis, copy and other sequence without an external computer.
HARDCOPY
Dump Mode Copy the CRT display to a graphics printer
Plot Mode Copy the traces, graticule and annotations to an HP-GL compatible digital plotter
Print Mode Copy measurement data in tabular form to a printer
Hardcopy of traces, measurement data, results of analysis and annotations are produced by the 4195A and HP plotters or printers with LISTEN only capability.
STORAGE
Instrument state, trace data, table of Program Sweep and User Program can be independently saved or recalled from the built-in 3.5 inch floppy disk memory via SAVE/GET function.
Instrument state includes active control setting of measurement, active calibration data, active display format, active scale setting, User Math and User Define Function.
