4 Possibilities of use
4.1 Super-counters
Additional equipment: SIRIUS with at least one CNT module (ACC+, …).
DewesoftX’s super-counters work on a 102.4 MHz internal time base, always, independent of the current
sample rate. In comparison to standard counters, which only output whole numbers like 1,1,2,2,3,4, … one
sample later, DewesoftX ® is able to extract the accurate values like 1.37, 1.87, 2.37, … fully time- and
amplitude-synchronized. This is done by measuring the exact time of the rising edge of the signal with
an additional counter.

Frequency/super-counter mode has many advantages over traditional counter measurements.
The problem with traditional counters is that the value of the counter is latched only at a sample rate
interval. Therefore, we only have discrete values on each sample. Since the counters can measure exactly
where the position of the pulse is between two samples, we can calculate two things out of this: the
exact interpolated position of the counter at the sample point, as well as the exact frequency of the
pulses.
We connect the encoder to the CNT module. In DewesoftX ® software, we add the Counters.
