Introduction

The focus of this tutorial is to introduce the user to transmitter (Tx), receiver (Rx) and transceiver (RT) models in EMIT by building a simple 1-Tx/1-Rx scenario. The simulation will be run using a fixed value for the antenna-to-antenna coupling and the resulting EMI margin examined. An interference will be identified and mitigated via the addition of a filter.

Key Concepts

• Add Radios to an EMIT design

• Define Tx and Rx Bands

• Run a 1-on-1 simulation

• Interpretation of results

• Mitigation using a filter

Project Configuration

A pictorial representation of the scenario we will analyze is shown below. A single Tx and Rx operating at different frequencies are evaluated for interference. The antenna-to-antenna coupling in this tutorial will be modeled using a fixed, frequency-independent value. The Tx is operating at a frequency of 50 MHz and a peak power level of 40 dBm. The Rx is tuned to 500 MHz and the in-channel susceptibility is -100 dBm.
