YBA250 NetTek Antenna and Transmission Line Analyzer SW Version 1.304

Major Changes For This Release
------------------------------

· This release supports both the NetTek Y350C and Y400 platforms. The serial upgrade procedure automatically determines the platform type and installs the correct application for the given platform.

· The CW source can now be turned on and off within the CW measurement screen.

· In DTF, you can now “zoom in” after setting a cover distance by simply changing the stop setting to a value smaller than the cover distance.

· The currently selected cable type is now displayed in the DTF measurement screen.

· The user now has the option to apply a "smoothing" algorithm on the DTF waveform when the number of waveform display points is less than 128. Smoothing can be enabled and disabled via a selection in the View menu or in the Distance Options page of the Setup dialog. 

· Application module power usage configuration queries have been updated to more accurately reflect that of a typical YBA250 module. The newly specified power usage is less than that specified in previous releases. This change, along with a future YBT250 release, will allow both the YBA250 and YBT250 to perform measurements simultaneously.

· In all previous releases, an alarm would occur in the return loss measurement when the measured result was physically below the specified mask limit. Given that down is good and up is bad in this measurement, this behavior was backwards of what was really needed. Therefore, in this release, return loss measurement alarms now occur when the measurement result is physically above the limit line.

· “Indoor Viewing” and “Outdoor Viewing” color schemes have been added. The outdoor scheme changes the return loss and DTF measurement result area to have a black background and green waveform trace. In addition, the display brightness is set to the maximum level. The indoor scheme uses the standard white background and blue waveform trace for the return loss and DTF measurement result area. It does not modify the display brightness.

· Added the GSM-R 900 channel table.

· Band edge cursors are now by default enabled.

· Fixed a problem where in some cases the IF Gain and IF Attenuation extended diagnostic tests would incorrectly report a failure.

Installation
------------

1) Unpack the ZIP file downloaded from the web.

2) Run YBA250Setup_v1-304a.exe and follow the on-screen instructions provided by the upgrade wizard. 


NOTES
-----

· The YBA250 upgrade process can be performed using either the Y350C or Y400 NetTek Analyzer platform. Once the upgrade process has successfully completed the YBA250 can be used on either platform.

· The installation utility is all that differs between the YBA250Setup_v1-304a.exe file and the previous YBA250Setup.exe release. The installation utility has been corrected to address SW installation failures that were observed for some YBA250 application modules. The resulting SW that is installed on the application module is the same 1.304 SW release.
