The 71500A microwave transition analyzer is a two-channel sampler-based time-domain instrument for making stimulus-response measurements from DC to 40 GHz. 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 the 71500A are programmable. In addition, custom application-specific interfaces can be developed for Keysight Instrument BASIC and run internally. This use of IBASIC eliminates the need for an external controller in many applications.
