pll test

Can somebody give me some advice and papers?
Thanks a lot!

Do you mean the spread spectrum function implemented in modern clock generators for mainboard?

Some one told me it is diffrent to test the spread spectrum PLL
with conventional PLL, so i ask for help!

Are you asking the frequency hopping SS?

What's the major application of the PLL, communication or clock generator?

Just using oscilloscope w/ enough BW and memory, then do FFT analysis.
