What is acquisition range of PLL?

[rlagusrb24]

Hi.

I have some problems of understanding of acquisition range of PLL.

My book says that type I PLL has low acquisition range and type II PLL has high acquisition range because it has frequency detector.

I want to know 1) the definition of acquisition range in PLL, 2) and why frequency detector makes type II PLL to have higher acquisition range compared to type I PLL. My book gives too ambiguous explanations so i need more precise one.

Thanks for your help.
