BUTTONS

The main program window has these buttons:
•
The Load Setup and Save Setup buttons load a setup
file and save the current setup to a setup file.
•
The Reset button issues a master reset to the device
(all registers are cleared and return to default values).
•
The I/O Config button displays the I/O Config
Interface where the user can specify whether to
communicate with the device in parallel or serial
mode. (The PC always communicates with the
evaluation board in parallel mode).
•
The FUD (Frequency Update) button issues a
frequency update signal to the device. This updates
the digital data being used by the DDS core to the
current values stored in memory. Note that a submenu
appears when the FUD button is clicked, allowing the
user to specify whether the program should
automatically issue FUDs or wait for the user to click
the button.

MENUS

The AD9858 evaluation software is a menu-driven interface.
This section describes the menus and associated commands.

View
This menu allows the user to display various interface windows.
Brief descriptions are given below for each of these windows,
with detailed sections following.
•
In the Preferences window, users can change the
display color.
•
In the Control window, the user programs information
about the clock, the power-down features, and the
output options. The user can also set miscellaneous
control register flags here.
•
The Profiles window shows the current values for each
of the user-defined profiles, allows the user to click a
name to select a profile, and enables the user to set the
parameters for frequency sweeping.
•
The PLL Fast Lock window can be used to specify
whether the device should use the PLL Fast Lock
algorithm, and if so, what parameters it should
incorporate into that algorithm.
•
The Readback window displays all data currently
programmed into the AD9858 memory registers.
