DEMO MANUAL DC1732
Software
The DC1371 is controlled by the PScope system software
provided or downloaded from the Linear Technology
website at
http://www.linear.com/software/
To start the data collection software if “PScope.exe”, is
installed (by default) in \Program Files\LTC\PScope\, double
click the PScope icon or bring up the run window under
the start menu and browse to the PScope directory and
select PScope.
If the DC1732 demonstration circuit is properly connected
to the DC1371, PSCOPE should automatically detect the
DC1732, and configure itself accordingly.
If everything is hooked up properly, powered and a suit-
able convert clock is present, clicking the “Collect” button
should result in time and frequency plots displayed in
the PScope window. Additional information and help for
PScope is available in the DC1371 quick start guide and in
the online help available within the PScope program itself.
Serial Programming
PScope has the ability to program the DC1732 board
serially through the DC1371. There are several options
available in the LTM9012 family that are only available
through serially programming. PScope allows all of these
features to be tested.
These options are available by first clicking on the “Set
Demo Bd Options” icon on the PScope toolbar (Figure 3).
This will bring up the menu shown in Figure 4.
