Delcross Technologies has announced the release of the Electromagnetic Interference Toolkit (EMIT) version 3.4 software offering an array of new features such as 13 new pre-defined transceiver, receiver and transmitter definitions for commercial radio systems and the ability to define noise sources for receiver desense analysis applications.
Designed to address RF cosite interference between two more more RF systems in the same complex environment, EMIT version 3.4 is suitable for RF EMI and RF systems engineers working with commercial handsets, wireless terminals, short-range commercial communications links, and interference between cellular radio systems and radio systems used in aerospace and defense, the company says.
The release introduces 13 new predefined commercial radio definitions to the EMIT system library with the aim of reducing setup time for many cosite analyses. These radio definitions cover both architectures and programming, including channel definitions, channel bandwidths, modulation type, noise levels, spectral profiles, power levels, MDS, intermodulation, harmonic and mixer products, frequency hopping definitions, and other key system parameters that influence the spectral behavior of RF systems. The new radio definitions also include GSM, LTE, UMTS, Bluetooth, 802.11 (WiFi), 802.11ad (WiGig), 802.16-2012 (WiMax), 802.15.4-2011 (ZigBee), GPS (L1/L2 bands), and GLONASS ( L1/L2) definitions. New cellular transceiver definitions provide both mobile and base station definitions.
EMIT version 3.4 also provides new digital noise sources suitable for use in receiver desense analysis to model unintentional radiators. According to the company, the new noise waveform definitions include trapezoidal clock (rise/hold/fall) with duty cycle, pseudo random bit stream (PRBS), common-mode differential pair skew noise, and spread spectrum clock (SSC) signals.
