Use the RF Settings section to control the output frequency.
You can type the desired output frequency in the RF VCO
Output Frequency text box (in MHz).
The Settings section lets you select general options available for
the PLL, including the charge pump current settings and phase
detector polarity. The

In the Registers tab, you can manually input the desired value
to be written to the registers.
In the Sweep and Hop tab, you can make the device sweep a
range of frequencies or hop between two set frequencies.
In the Latches/Registers section at the bottom of the window,
the values to be written to each register are displayed. If the
background on the text box is green, the value displayed is
different from the value actually on the device. Click Write R
Counter Latch or Write N Counter Latch to write that value
to the device. To update all latches in the correct order, click
