Intermodulation Analysis System
Save time during RF setup and coordination.
Intermodulation Analysis System (IAS)
by Professional Wireless Systems is a must-have for every RF engineer. IAS saves precious setup time by combining a database of wireless performance equipment and access to local television frequencies in use. This means an RF technician need only enter their current zip code and inventory the gear and frequencies in use. IAS will perform multiple calculations to find open frequencies that are free from overlapping analog and digital TV signals and intermodulation distortion. This saves tremendous time over traditional trial-and-error methods. Once a clean frequency is found in IAS, a simple pre-show equipment test will verify the software’s “offline” analysis.
New in IAS 5.0
Ribbon menu tool bar enhances the user experience for touchscreens and provides easier workflor from start to finish.
Enhanced calculation features with the ability to lock frequencies from changing.
Better international support allowing users to block out restricted bands in their country.
Improved spectrum graph shows a device's tuning bands to better visualize limitations of coordinations.
Database of pre-built models include channel assignments (such as group and channel information), eliminating the need to carry frequency charts for a various models of wireless systems.
Specific details also include channel assignments (such as group and channel information, eliminating the need to carry frequency charts for a various models of wireless systems.
Zone support for coordination’s over large venues such as convention centers and hotels.
Effectively unlimited number of frequencies supported in each coordination (Professional Edition). Limits are imposed solely by compatible frequencies, not storage or computational ability of the software.
Improved graphical view of Frequencies, TV stations and IMD products which allows the user to find “open holes” and make educated decisions about the best use of the available spectrum.
Improvements and Bug Fixes in 188.8.131.52:
IMPROVEMENT: Modified the Lectrosonics models to yield more reliable candadite frequencies.
BUG FIX: Modified select model definitions with incorrect presets
BUG FIX: Having multiple country's broadcaster data downloaded would cause the TV Wizard to use the wrong country when performing a search.
BUG FIX: Under certain circumstances, files saved with v184.108.40.206 cannot be opend with later versions without an error. All users are encouraged to update to v220.127.116.11 to correct this problem.
BUG FIX: VHF DTV and NTSC channels could be set, but not un-set from the context menu.
BUG FIX: The update notification feature could be prevented from indicating that new version is available in v18.104.22.168.
BUG FIX: Using the "&" character in a unit's channel name would cause an unhandled exception.
BUG FIX: RF Sweeps would not upload if the "Location" name was too long. A character limit now verifies text entries.

Frequently Asked Questions
How do I change my name and company that is printed on the report?
In version 5, the information printed on your report is associated with your license and is pre-populated with the information you used when registering the software. This can be changed with the following steps:
Click on the IAS logo in the top left to show the application menu.
At the bottom of the application menu, click the License link
Make the desired changes to the editable text fields
Click the Register buttons to save changes
Note that the text fields may not be left blank or they will automatically repopulate with information from your license registration.
I have a problem regarding licensing when using Parallels or Fusion and Boot Camp.
This problem only occurs when using Apple hardware and virtualization technology. Virtual machines have a different hardware fingerprint than your host computer and will confuse the licensing system when switching back and forth. The straightforward answer is to use only one platform when using IAS. IAS 5.0, however, provides users with an interface to manage their licenses themselves in an effort to make switching easier without having to contact PWS for support.
Is there a native version for Macintosh available?
IAS has evolved significantly since its first release. Initially it was built on a Windows-only platform and has since been entirely restructured in preparation for cross-platform compatibility. IAS 5.0 is the first release using the new structure and is a great step forward. While not available yet, a Macintosh version is in the list of future goals.
I experience a "No Association for File Extension" error message when printing.
On some systems, HTML files are not associated with any particular application and Windows does not know how to open them. IAS renders reports out to a simple webpage that is compatible with all PCs and tablets. Autonomously opening the file, though, can sometimes be a problem. To fix this, follow these steps:
Open the Windows Control Panel.
In the search bar type “Set your Default Programs” and then open the associated entry in the Control Panel.
Select “Internet Explorer”.
Select “Chose Defaults for this program” and Check the Box for .html.
