The Main Controls tab controls the PLL settings (see Figure 32).
Use the Reference Frequency text box to set the correct
reference frequency and the reference frequency divider. The
default reference frequency in this box is at 10 MHz.
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 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 Latches/Registers section at the bottom of the Main
Controls tab of the main 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.
