resting at a negative voltage preventing proper VCO operation. The PLL will not lock in
this condition. If this mode occurs, the power supply for Op Amp (± 6V) should be
cycled.

1. Turn on power supplies for PLL VDD and VCO VCC.
2. Program PLL.
3. Turn on the power supply for the Op Amp.
Select the PE3336 from the pull-down menu button in the upper left corner of
the program screen. This selection will enable certain product specific modes
of operation.
If the on-board reference is being used, set the reference frequency to 10 MHz
by typing 10 into the reference frequency box. If an external reference is
applied, type in the appropriate reference value in MHz.
Set reference counter (R counter) to 9 by entering it into the R counter box in
the "R M A Select" box in the bottom left corner. Note that the numbers in the
orange boxes are computed values and cannot be directly typed in.
Verify frequency step = 1.000 MHz.
Set Frequency to 3000 MHz by typing it into the secondary register frequency
box. Once the frequency values are entered by "Enter" key in the keyboard,
the software will automatically send out data to program PLL. You can also
click the "Send Data" button to program PLL.
Verify on the spectrum analyzer that the part locks at 3000 MHz.
To prevent this from happening, the following power on sequence is
