Preliminary Technical Data
Board LDO Regulator Control
The on-board regulators are controlled from the main software
panel. Each regulator can be individually turned on or off as
shown in Figure 10. This is useful for observing the current
drawn by each device. For example when measuring the current
drawn in receive, the on-board buffer and PA supplies can be
powered down in order to view the current drawn by the
ADF4602 and AD9863 alone.

Loading and Saving Settings
Register settings for both the ADF4602 and AD9863 can be
saved individually for future use. This feature is useful as there
are many registers in both devices and programming each
individually is time consuming.
To save settings, click on File->Save ADF4602 setup or Save
AD9863 setup. Loading saved files is achieved by clicking on
the corresponding Load option.
When a file is loaded, the filename is shown in the Current
Setup frame in the top left hand corner of the screen. Having
loaded settings files for each device, a Load All should be
performed on both devices to initialize them correctly.
Help
Hovering the mouse pointer over the register text will give a
description of the register function.
ADF4602 R0.1 Silicon Soft Reset
A soft reset must be performed on the ADF4602 R0.1 silicon
after power up for correct operation. To do this, load all
registers, then toggle the soft reset button in register 2, and then
load all registers again.
Default Configurations
A number of default software configurations are provided for
easy setup of the evaluation board. It is recommended that these
be used when first using the evaluation board. Table 1 shows the
files that come with the evaluation software.
Compatibility with Visual Analog software
The Visual Analog software and the EVAL-ADF4602EB1Z
software should not be operated simultaneously on a single
PC/laptop. This is due to the incompatibility of the USB drivers.
The Visual Analog software must be run on a separate PC.
