Features
Table 1 lists the key features of the DT3034 board.
• Programmable bipolar (±10 V) and unipolar (0 to 10 V) input ranges with gains of 1, 2, 4,
and 8; fixed output range of ±10 V
• Continuously-paced and triggered scan capability
• A 1024-location channel list that supports sampling analog input channels at the same or
different gains in sequential or random order
• Up to 256 scans per trigger for a total of 262,144 samples per trigger
• PCI bus mastering for data transfers
• Pre-, post-, and about-trigger acquisition modes to acquire data relative to an external
event using computer memory
• Internal and external clock sources; one external clock input for the analog input
subsystem and one external clock input for the analog output subsystem
• Analog threshold triggering using either an external analog input or one of the analog
input channels; a separate DAC sets the trigger level (8-bit resolution, fixed hysteresis)
• Digital TTL triggering; one external hardware TTL input for the analog input subsystem
and one external hardware TTL input for the analog output subsystem
• Simultaneous analog input and analog output operations running at full speed
• Software calibration of the analog input and output subsystems
• Two 8-bit digital ports programmable as inputs or outputs on a per-port basis; digital
inputs can be included as part of the analog input channel list to correlate the timing of
analog and digital events; digital outputs can drive external solid-state relays
