F-55103-2-CTI Common Mode Test Interface

Introduction
The F-55103-2-CTI has been specially designed for use in performing common mode immunity testing on balanced audio input ports and simple balanced control ports per EN 55103-2 Section B.2.1 Figure B.1. The test method described in B.2.1.1 involves injecting the disturbance signal in to the EUT port via capacities coupling. The test interface is shown below.
Per Specification, the F-55103-2-CTI requires an input of -20duV between 50 Hz - 10 kHz. The F-55103-2-CTI also comes with a calibration adapter per Figure B.2 for setting the immunity level prior to testing simple control ports.
