Agilent / HP / Keysight 71500A

This Microwave Transition Analyzer is a two channel sampler based time domain instrument for making stimulus response measurements from DC to 40GHz.

It is ideal for characterizing components and systems in a benchtop environment.

You can measure rise and fall times, time delay, peak and average power, group delay, AM to PM conversion, and much, much more.

All functions of this unit is programmable.

In addition, custom application specific interfaces can be developed for Agilent Instrument BASIC and run internally.

This use of IBASIC eliminates the need for an external controller in many applications.
