File Menu
The
File
menu allows you to load a previously saved AD9523
setup file or to save a new AD9523 setup file. A setup file (.stp)
is a text file that contains the AD9523 register setup file, plus
any evaluation board settings.
To load a previously saved setup file, select
Load Setup
from
the
File
menu. Note that you must still perform a VCO
calibration. Alternatively, to save a new setup file, select
Save
Setup
from the
File
menu.
To exit the evaluation software, select
Exit
from the
File
menu.
However, note that you must save your setup before exiting; no
checking is performed to ensure that the existing setup is saved.

Selecting
Configure Serial Port
from the
I/O
menu allows you
to control how the USB controller interacts with the AD9523 serial
port (see Figure 8) by configuring Register 0x0000 (shown as
0000h
in Figure 10).
The serial port configuration window allows you to control how
the USB controller interacts with the AD9523 serial port. If you
are using I
2
C mode, this window allows you to select which
address to use. Note that it should correspond to the settings of
Jumpers P5 and P6 on the evaluation board. You can also click
the
Detect Current Configuration
button to have the
evaluation software discover which I
2
C address is active.
