Software
The DC890 is controlled by the PScope System Software
provided or downloaded from the Linear Technology
website at http://www.linear.com/software/. If a DC890
was provided, follow the DC890 Quick Start Guide and
the instructions below.
To start the data collection software if PScope.exe is in-
stalled (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 DC1369A demonstration circuit is properly connected
to the DC890, PScope should automatically detect the
DC1369A, and configure itself accordingly. If necessary
the procedure below explains how to manually configure
PScope.
Under the Configure menu, go to "ADC Configuration...."
Check the Config Manually box and use the following
configuration options (see Figure 2):
DEMO MANUAL DC1369A
Manual Configuration settings:
Bits: 14 (or 12 for 12-bit parts)
Alignment: 14
FPGA Ld: DDR LVDS
Channs: 2
Bipolar: Checked
Positive-Edge Clk: Checked
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 DC890 Quick Start Guide and in
the online help available within the PScope program itself.
