Timing Test

If specific antennas have to be matched to a transponder IC, the Timing Test feature can be used to
determine the appropriate write timing needed for OOK data downlink. The write time ranges for logical
one, logical zero, and gap can be defined. When the Start Test button is clicked, data is written to the tag
starting with the minimal time values. Following this, the programmed data content will be read back and
verified, and the results displayed in the window.

The write-read-compare procedure continues through all the time ranges with the specified time step
width. The current time settings of the write execution with related results are displayed in a table. When
the timing test is finished, the resulting table can be printed or saved to the directory where the program
was started.

The test is restricted to a defined transponder configuration as follows:
