The Main Controls tab controls the PLL settings (see Figure 19).

Use the Reference Frequency text box to set the correct

reference frequency and the reference frequency divider. The

default reference on the software window is 25 MHz.

Use the RF Settings section to control the output frequency.

You can type the desired output frequency in the RF Frequency

text box (in megahertz).

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 Registers section at the bottom of the Main Controls

tab, 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 Rx

(where x = 0 to 5) to write that value to the device.
