dc890bf
DEMO MANUAL DC890B
The DC890B provides system status via eight LEDs:
LED-1. TRANSFER – Indicates a USB data transfer from
the PScope to the PC is in progress.
LED-2. SEEP – Indicates access of the optional demon-
stration circuit serial electrically erasable PROM on
select demonstration boards. Information in this
SEEP permits PScope software to configure the
DC890B properly for the device under evaluation
using the auto detect demo board feature in the
configure/device menu.
LED-3. RST – Indicates assertion of either a hard or soft
reset.
LED-4. DCM_RDY– In LVDS mode, LED 4 blinks to alert
the user that the sample clock is either not present
LED INDICATORS
or outside the required frequency range (F
IN
must
be > 50 MHz). A steady on condition indicates the
digital clock module is locked to the input sample
clock. In CMOS mode LED 4 functions as a power-
on/FPGA programmed Indicator.
LED-5. RUN ON TRIGGER – Indicates that the board is
set to run on trigger (versus halt on trigger mode).
LED-6. DATA_RDY – Indicates completion of data block
acquisition.
LED-7. RUN – Indicates the board is ARMED to collect a
block of data.
LED-8. TRIGGER – Indicates that a trigger was received
and data collection has started.
A schematic, parts list and parts placement drawings are
attached to the end of this quick start guide for reference
only.
