Frequency ramp generating method
Frequency ramps are generated between a start frequency (fi) and an end frequency (f2) in a partial time interval (ti). The partial time interval corresponds to the period (Ti-1)of the frequency (fi-1) of the previous pulses. The individual pulses are integrated to an absolute ramp time (tr), and th...

Zusammenfassung: | Frequency ramps are generated between a start frequency (fi) and an end frequency (f2) in a partial time interval (ti). The partial time interval corresponds to the period (Ti-1)of the frequency (fi-1) of the previous pulses. The individual pulses are integrated to an absolute ramp time (tr), and then multiplied by a predetermined acceleration value (a) for the actual pulse of the frequency (fi) to be reached. The period (Ti) is obtained form the reciprocal of the frequency (fi). The ramp time (tr) is set to a start value of 0 during the partial time period before the ramp starts. |
