The user interface (Figure 1) is easy to operate: use the
mouse, or a combination of the tab and arrow keys to
manipulate the software. Each of the buttons corre-
sponds to bits in the command and configuration
bytes. By clicking on them, the correct SPI write opera-
tion is generated to update the internal registers of the
MAX19700. Note: Words in bold represent visible items
on the graphical user interface (GUI).
The software divides EV kit functions into logical
blocks. The Interface box indicates the current Device,
the Register Address Sent, and the Data
Sent/Received for the last write operation. This data is
used to confirm proper device operation. Adjust the
SPI Clock Frequency through the pulldown box.
The controls for the Tx DAC and Auxiliary DACs are
accessed through tab sheets. Device Control is
accessed at the right-hand side of the main window.
Return the EV kit to its power-on-reset state by clicking
the POR Reset button.
The MAX19700 EV kit software features additional func-
tions to simplify operation. Automatic Diagnostics
probes the command module board to make sure that
a connection exists between the PC and the command
module.

User-Interface Panel
Configure the operating mode of the device through the
intuitive controls in the Device Control box. Select a
mode as outlined in the MAX19700 data sheet using
the Operating Mode control. For a detailed description
of the MAX19700 operating modes and their specific
names, refer to the Power-Management Modes table in
the MAX19700 data sheet.
When using SPI Tx/Rx Control, ensure that jumper
JU3 is set appropriately. See the Digital Data Direction
section in this document for details regarding JU3.
Adjust the Common-Mode Voltage and the DAC Full-
Scale voltage by selecting the desired option from the
pulldown box.
The DAC I-Offset and Q-Offset voltages can be adjust-
ed in 801.5µV/977.5µV increments by adjusting the
appropriate slider in the Tx DAC Offset Control box.
The increment value is dependent on the DAC Full-
Scale range. A full-scale range of 820mV
801.5µV increment. A full-scale range of 1V
977.5µV increment. Alternatively, a number (specified
in millivolts) can be entered in the boxes below each
slider. If a number not divisible by 0.8015/0.9775 is
entered, the software automatically rounds the number
to the nearest 801.5µV/977.5µV increment and sends
the appropriate data to the MAX19700.
