Delcross EMIT Version 4.0 New Features
March 31, 2015
User Interface
-
Dockable Windows
o Any window within EMIT can be made dockable and placed (docked) in a fixed position
within the main EMIT interface.
o Docked windows can be arranged in many different configurations to suit user
preferences.
o Any combination of docked and regular windows can be used simultaneously for
maximum flexibility.
o Docked windows can be placed outside of the main EMIT user interface. This is
particularly useful when using multiple computer monitors.
-
Multiple linked views for setting up scenarios and viewing & analyzing results:
o Configuration Diagram for configuring RF systems graphically with “drag & drop”
component placement and connection.
o Scenario Matrix (formerly System View)
o Scenario Details provides an intuitive tree structure for navigating results.
o Interaction Diagram shows all, or selected parts, of the scenario and identifies the
worst-case interference path.
o Results Categorization permits filtering of results to display only specific interference
mechanisms for rapid “root-cause” problem ID.
o EMI Margin Plot (formerly part of Results View)
o Selections in any one view are reflected in all others
EMIT Version 4.0 New Features and Enhancements
March 31, 2015
Library and RF Equipment Databases
-
Improved Library Tree with custom grouping of models via multi-level folders.
Improved organization of the Delcross radio library makes it easier to find and use models based
on system function.
Deferred loading of libraries provides improved performance by loading libraries only when you
need them instead of at start-up.
EMIT Analysis Engine
-
Numerous solver performance enhancements to run large simulations more than 10x faster
than before.
N-on-1 scenarios may be simulated in 2:1, 3:1 and progressively larger sets automatically in
order to more quickly resolve EMI issues arising when multiple transmitters are active
RF Systems
-
The structure of RF Systems in EMIT has been redesigned to provide a more intuitive definition
of physical systems.
RF Systems contain a collection of Radios and Components that define the physical hardware
present.
Configurations for an RF System define how the hardware is connected and operated within the
scenario.

EMIT Version 4.0 New Features and Enhancements
-
March 31, 2015
Support is provided for multiple Configurations within a single RF System.
Radio Model Enhancements
-
-
Option to specify intercept and compression points for Tx’s and Rx’s when available to include
internally generated intermodulation products.
Architecture and Programming nodes have been eliminated for more intuitive radio definition
channel sampling.
User-defined Tx emissions spectrum:
o Create custom in-band emission masks
o Create custom frequency-dependent broadband noise
o Define via table input or CSV file import.
Automatic parsing of ITU emission designators.
Support for radios with multiple antenna ports.
DD-1494 Mode facilitates the entry of RF equipment characteristics from DD-1494’s into EMIT
by configuring the data entry fields in EMIT to correspond directly to those in the DD-1494.
Band definition has been simplified by moving advanced settings like mixer products, selectivity
tables, spurious emissions, etc. to optional child nodes of the Band that are included only when
required.
Outboard RF Component Models
-
-
New outboard component models including:
o Circulators
o Isolators
o Multiplexers
o Power Dividers
Includes both parametric models and definition via Touchstone import
Results Display and Interference Diagnostics
-
Customize any number of interference thresholds (and associated colors) based on EMI margin
levels.
Visualization of EMI margins for all system pairs regardless of whether the EMI margin exceeds
the user-defined threshold for interference.

EMIT Version 4.0 New Features and Enhancements
-
March 31, 2015
Markers on result plots immediately show the source of the worst-case interference including
identification of intermodulation products.
Plot signal spectra at any point in the signal paths to facilitate analysis and troubleshooting of
complex scenarios.
Automatic graphical identification of interference paths via the new Interaction Diagram
Filter results by interference type to display only specific types of problems.
Other Usability Enhancements
-
-
-
Project and Library Locking: EMIT now locks projects when they are loaded. Locking the project
prevents another EMIT session from loading the same project at the same time and corrupting
the project by trying to edit it concurrently. Subsequent EMIT sessions that open a locked
project will detect that the project is already in use and offer the chance to do a Save As... action
to create a new copy of the project that can be edited safely.
Save EMIT 3.0 Project Before Upconvert: EMIT offers a chance to save projects created in
earlier versions of EMIT before editing in newer versions. EMIT performs a step called
upconverting a project if the project was created with an earlier version. The upconvert step
translates the project settings into the format used by the latest version. Users are now given
the option to save a copy of the original project, without any upconvert changes, to preserve the
original project.
Worst-case “EM Isolation” for imported coupling data.
“Position-less Antennas” - antennas are no longer required to have a position specified
Export any plotted data to a CSV file.
Enhanced Plot Markers.
Add an Image background to plots.
CAD Units scaling
Full Linux support.
