Main settings (see the screenshot in

Figure 2):

a)

Device choice (STW81101, STW81102, STW81103)

b)

Output frequency [MHz]

c)

Frequency step [kHz]

d)

Output stage (direct output, divider by 2, divider by 4)

e)

VCO and phase detector frequencies are calculated from the inserted data.

f)

A table helps to choose the correct output stage depending on the desired output

frequency and the selected device.
