INTRODUCTION

of PWM circuits using the MSA240KC/260KC pin out. With

ample bread boarding areas it is flexible enough to analyze

a multitude of standard or proprietary circuit configurations.

Critical connections for power supply bypassing are pre-wired.

Components not usually readily available in engineering labs

are provided. External connection to the evaluation kit can be

made via the terminal block and banana jacks at the edges

of the circuit board.

BEFORE YOU GET STARTED

• All A pex Precision Power amplifiers should be handled using

• Do not change connections while the circuit is powered.

• Initially set all power supplies to the minimum operating
