DEMO MANUAL DC1763A
QUICK START PROCEDURE
If the DC1763A demonstration circuit is properly connected
to the DC1371, PScope should automatically detect the
DC1763A, and configure itself accordingly. If everything is
hooked up properly, powered and a suitable convert clock
is present, clicking the Collect button should result in time
and frequency plots displayed in the PScope window. Ad-
ditional 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 DC1763A board
serially through the DC1371. There are several options
available in the LTC2195 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 2).
