DEMO MANUAL DC1760A
QUICK START PROCEDURE
Output Mode: Selects Digital output mode.
• Full Rate (Default) – Full rate CMOS output mode (This
mode is not supported by the DC1760A).
• Double LVDS – double data rate LVDS output mode
• Double CMOS – double data rate CMOS output mode
(This mode is not supported by the DC1760A).
Test Pattern: Selects Digital output test patterns.
• Off (Default) – ADC data presented at output
• All out =1 – All digital outputs are 1
• All out = 0 – All digital outputs are 0
• Checkerboard - OF , and D13-D0 Alternate between 101
0101 1010 0101 and 010 1010 0101 1010 on alternat-
ing samples.
• Alternating – Digital outputs alternate between all 1's
and all 0's on alternating samples.

Alternate Bit: Alternate Bit Polarity (ABP) mode.
• Off (Default) – Disables alternate bit polarity
• On – Enables alternate bit polarity (Before enabling ABP ,
be sure the part is in offset binary mode)
Randomizer: Enables Data Output Randomizer.
• Off (Default) – Disables data output randomizer
• On – Enables data output randomizer
Two's Complement: Enables two's complement mode.
• Off (Default) – Selects offset binary mode
• On – Selects two's complement mode
Once the desired settings are selected hit OK and PScope
will automatically update the register of the device on the
DC1760A demo board.
