1. Introduction This document describes in detail how the GUI works with the Mini-Circuits system controller and signal generator, the Mini-Circuits’ ISC-2425-25+ module. The Graphical User Interface (GUI) is intended for use in single channel systems. The GUI acts as the primary Human-Machine Interface between the user and the ISC board.

This means that at 1000 Hz, the minimum duty cycle is 5% and at 19800 Hz it is 99%. Going over this frequency value would effectively disable PWM, as the minimum duty cycle becomes 100%.
