Added support for multi-counter backplane PCB ability to select individual DUT PCBs. 280A Revision 10.40 09/20 1. Revision 1.63 added the option for frequency reference "Ref Fr Minus Offset". It was not implemented correctly and was actually adding the offset. In the last revision (10.30), "Ref Fr Minus Offset" was removed. "Ref Fr Plus Offset" was added and all QCO files that were using "Ref Fr Minus Offset" were changed to "Ref Fr Plus Offset". This revision adds "Ref Fr Minus Offset" but implements it correctly. 280A Revision 10.30 08/20 1. The frequency reference option "Ref Fr Minus Offset" was introduced in revision 1.63 in 2004. However, it was implemented in the software as "Ref Fr Plus Offset". This version changes the option name to match the behavior. 280A Revision 10.22 08/20 1. Allow 0 or negative values when the frequency reference for a test type is "Ref Fr Minus Offset". 280A Revision 10.21 08/20 1.

Added test types CF0, CF1, CF2, CF3, CF4, CF5, and CF6. The main purpose was to allow the operator to specify a different temperature offset than 26 C. This also allows the customer to get the curve-fit coefficients for 5th and 6th order curve-fit. 3. Added test types ttA5, ttA6, ttTP4, ttTP5, ttIT3, and ttIT4 because the W-2800 is now going to allow up to 6th order curve fit. 4. Fixed a bug on scaling in the graphs on the main screen in some cases. 5. When the W-280A/B was used as an OLE server (such as in the W-5920), sometimes the scroll bar for the measurement list would be disabled when there were measurements available for scrolling. This has been corrected. 280A Revision 8.46 08/12 1. Added support for WR610Zi oscilloscope. 280A Revision 8.45 07/12 1. No user significant change. 280A Revision 8.44 07/12 1.

Fixed Etching parameters screen not displaying correctly with 3 etching cycles and port offsets (<12 ports) selected. 2. Enabled XP look and feel. 280A Revision 8.42 07/12 1. In previous revisions, if a QCO file was selected that could not be loaded, the previous QCO file was loaded, but the name was changed to the desired filename. This was confusing, incorrect, and could cause the file to get overwritten. Now, when previous file is reloaded, the filename is not changed. 280A Revision 8.41 05/12 1. Fixed a bug since revision 7.97 that could cause the W-2800 or other OLE client applications to generate an error message, hang up, or close the application when using the LAN for instruments. 280A Revision 8.40 05/12 1. Fixed a bug from revision 8.39 that would not display the fail ICON on the main screen when the test failed. 2. Since revision 7.97, it was possible for the application to hang when making multiple (more than 500) measurements through OLE or the W-2800. This has been corrected. 280A Revision 8.39 05/12 1. Fixed a bug that could cause the OLE interface to hang up on certain measurement calls, for example MeasureAndGetBinNumber. Revision 8.38 04/12 1.
