7.7.2 Modulation
This dialog permits to define the tolerance limits for the B-field modulation, the frequency offset and the
frequency drift. Entered values are set by pressing OK. If newly entered limit values should not be set,
terminate the dialog with Cancel.
Set limits are indicated in the second and third column of the measurement report. Refer to the report
section shown below.
Notes:
Data type Fig31 is always used for the CTSgo measurements. Within the B-field, this implies a number
of 0/1s bit sequences, then a number of set bits (1s bits), followed by a number of set bits (0s bits) and
a final 0/1s bit sequence. On the average, this figure contains as many bits that are set as bits that are
not set in the B-field. If the arithmetic mean of the frequency offsets was generated, the result would
correspond to the center frequency in the ideal case. The deviation is the frequency offset measured.
Starting from this frequency offset, the maximum and the minimum deviation in the B-field will then be
measured, with no differentiation being made between positive and negative deviation.
The unit of the frequency drift can be entered in the respective box in kHz/slot. Otherwise, the output
will be in kHz/ms.
