WITE32 Release Notes Version 3.11
2.6 TAA Calibration Through Programmable Differentiator
Starting from WITE32 version 3.11, the calibration of amplification of programmable differentiator filters is not
performed during TAA calibration. All programmable differentiators are assumed to have the same amplification at
their cutoff frequencies as the Open filter. This means that if the spectral content of the signal is located below the
cutoff frequency of a programmable differentiator, then the amplitude measured through this differentiator will
decrease (approximately linearly) with the increase of the cutoff frequency.
In previous releases of WITE32, the amplification of the programmable differentiator was calibrated during TAA
calibration regardless of the current cutoff frequency and the calibration signal spectral content. This led to
unpredictable measurement results in the case of changes of the cutoff frequency or the signal frequency.
2.7 Error / Warning Report Modification
1. The information about WITE32 software version is added to the standard WITE32 error message box, when
shown in the More Info mode. The WITE32 software version is printed on the first line of the error report.
Figure 16 Error / Warning Dialog Box
2. The existing Errors at The Test End option is extended. In previous versions of WITE32, if this option is
enabled, the buffered messages are only shown in a separate dialog box at the end of the production test. In
WITE32 version 3.11 you can specify a log file name, such that the buffered error messages are also appended to
the log file.
