DEMO MANUAL SCP-LT1964-EVALZ
QUICK START PROCEDURE
Demonstration circuit SCP-LT1964-EVALZ is easy to set
up to evaluate the performance of any SCP hardware
configuration.
1. The SCP-LT1964-EVALZ ships with a default output
voltage of –5V. To change the output voltage, see "Con-
figuration Settings" section, and modify the board ac-
cordingly. Be sure to check for open connections or sol-
der shorts after making any modifications.
2. Connect the SCP-INPUT-EVALZ and SCP-OUTPUT-
EVALZ boards to the SCP-LT1964-EVALZ (refer to Fig-
ure 2) and connect the input board to a voltage source,
V
. Connect the output board to a voltmeter or
SOURCE
dynamic load. Slowly raise the input voltage until the
SCP-LT1964-EVALZ powers up into regulation and
sweep V
through the desired range of operation.

NOTE: Make sure that the input voltage is always within
spec. If using a dynamic load to measure output volt-
age, make sure the load is initially set to zero.
3. Check for proper output voltage. The output should be
regulated at the programmed value (±5%).
4. Once the proper output voltage is established, power
off V
and similarly test other boards in the SCP
SOURCE
system until all elements have been individually verified
prior to assembling into the final circuit configuration.
NOTE: When measuring the input or output voltage rip-
ple, use the optional SMA connector locations available
on the input, output, 1 ´ 5, 1 ´ 2, and 5 ´ 1 breakout
boards. Avoid using the test point connections with
long scope leads.
