Introduction

The J2113A is a solid-state Semi-Floating Amplifier (SFA), or ground loop isolator, that provides the BEST isolation for low impedance measurements. The J2113A removes the groups loops associated with VNAs and Oscilloscopes which occur in many different types of test setups. The ground loops are often subtle or hidden and can impact the measurement results dramatically if not accounted for. The J2113As frequency response, as shown below, is flat from DC to over 800MHz, all while maintaining 50Ohm impedance at both the input and the output for accurate, low-noise measurements. It allows measurement both lower and higher in frequency than achievable with a Common Mode Transformer. The J2113A supports power distribution network (PDN) measurement, component measurement, PSRR testing and many other applications.
