Basic Measurements
As you will see many of the measurement instruments/functions listed previously do not physically exist, except in software as virtual instruments which can be easily reconfigured to create new instruments and measurement functions. To perform the complex measurement functions represented by the virtual instruments, the test system very quickly performs many, simple, low level measurements (I & Q voltage, RMS Power and DC current and voltage) and uses the processing speed and power of the system computer to calculate the test results desired (S parameters, RF power, noise figure, harmonics, intermodulation distortion, DC current and voltage, etc.)

Easily Reconfigured to Create New Instruments
Each of these virtual instruments have been created through software manipulations of a basic set of measurements. The process that defines these measurements will be explained for each one individually. Other virtual instruments can be created in the future, it is only limited by your imagination.
