In the example (a fig. 113), the first frequency jump(PNU A063) is at 15 Hz, the second (PNU A065) at 25 Hz <s<strong>tr</strong>ong>and</s<strong>tr</strong>ong> thethird (PNU A067) at 35 Hz. The jump widths (adjustable underPNU A064, A066 <s<strong>tr</strong>ong>and</s<strong>tr</strong>ong> A068) are set to 1 Hz in the example.f[Hz]35PNU A0612515PNU A0620tPNU b0820 10Figure 112: Upper frequency limit (PNU A061) <s<strong>tr</strong>ong>and</s<strong>tr</strong>ong> lower frequencylimit (PNU A062)U [V]>
