Connector
Access
Function
ARB OUT/
VIDEO OUT
Output
Provides the waveform output.
SYNC OUT
Output
Provides a TTL-level output of the waveform
being generated at the ARB OUT connector.
EXT TRIG
Input
Accepts a TTL-level signal that you can use to
start or step through a waveform generation.
MARKER OUT Output
Sends a TTL-level signal that you can set at any
point in the waveform being generated. You can
use this signal to synchronize or trigger other
devices at a certain time within waveform
generation.
PLL REF
Input
Accepts a PLL Reference clock from an
external source and can frequency lock the
NI PXI-5411/5431 Sample clock timebase to the
external Reference clock. You also can use this
connector as a source of the device Sample clock
from an external device.
DIGITAL
PATTERN/
VIDEO
DIGITAL
PATTERN
Input/Output
Routes 16-bit digital pattern outputs, digital
pattern clock output, marker output, external
trigger input, and +5 V power output. Refer to
the
NI Signal Generators Help
for connector pin
assignments and signal descriptions.
