 Using the DS_CONNECT option with the Connection argument for the cbSelectSignal() function
generates a BADCONNECTION error.
 Using the DsConnector option with the connectionPin parameter for the SelectSignal() method
generates a BADCONNECTION error.
Pacing analog input
Hardware pacing, external or internal clock supported. The clock edge is selectable through InstaCal and
cbSelectSignal / SelectSignal().
When using EXTCLOCK and BURSTMODE together, do not use the A/D External Pacer to supply the clock. Use
the A/D Start Trigger input instead. Since BURSTMODE is actually paced by the internal burst clock, specifying
EXTCLOCK when using BURSTMODE is equivalent to specifying EXTTRIGGER.
Except for SINGLEIO transfers, CONTINUOUS mode scans require enough memory for two packets, or 1024
samples. The packet size is 512 samples.
Analog input configuration
16 channel boards: The analog input mode may be 8 channel differential, 16 channel single-ended referenced
to ground or 16 channel single-ended non-referenced, and may be selected using InstaCal.
64-channel boards: The analog input mode may be 32 channel differential, 64 channel single-ended
referenced to ground, or 64 channel single-ended non-referenced, and may be selected using InstaCal.
Triggering and gating
Digital (TTL) hardware triggering is supported for the entire series. cbSetTrigger() / SetTrigger() is
supported for GATEHIGH, GATELOW, TRIGPOSEDGE, TRIGNEGEDGE.
The A/D PACER GATE input is used for gating with GATEHIGH or GATELOW. The A/D START TRIGGER input is used
for triggering with TRIGPOSEDGE and TRIGNEGEDGE.
When using cbAPretrig() or cbFilePretrig() / APretrig() or FilePretrig() , use the A/D Stop Trigger
input to supply the trigger.
For the PCI-DAS6030, PCI-DAS6031, PCI-DAS6032, PCI-DAS6033, PCI-DAS6040, PCI-DAS6052,
PCI-DAS6070 and PCI-DAS6071: Analog hardware triggering and gating are supported.
cbSetTrigger()/SetTrigger() is supported for TRIGABOVE, TRIGBELOW, GATENEGHYS, GATEPOSHYS,
GATEABOVE, GATEBELOW, GATEINWINDOW, GATEOUTWINDOW.
The analog trigger source may be set via InstaCal as either the ATRIG input (pin #43 on the I/O connector),
or as the first channel in the scan (CH# IN). To use the ATRIG input as the trigger source, set the InstaCal
"Analog Input Trig Source" to "Analog Trigger Pin." To use the first scanned channel as the trigger source,
set InstaCal to "1st Chan in the Scan."
Recommended trigger source when using analog gating features
If using analog gating features, we strongly recommend setting the ATRIG input as the trigger source.
Using the ATRIG input as the Trigger Input
When the trigger source is set to "Analog Trigger Pin," analog thresholds are set relative to the ± 10 V range.
Using the "First Channel in Scan" as the Trigger Input
When the trigger source is set to "1st Chan in Scan," the range used for the thresholds is the same as the A/D
channel. When using analog gating features with "1st Channel in Scan" as the trigger source, be careful to
only scan a single channel.
