DBK46 – Specifications
The four analog output channels are updated synchronously relative to scanned inputs, and are clocked
from either an internal clock on the primary acquisition device, such as a DaqBook/2000A; or from a user-
supplied external clock source. Analog outputs can also be updated asynchronously, independent of any
other scanning in the system.
Channels: 4
Resolution: 16 bits
Data Buffer: 256 K sample FIFO
Output Voltage Range: ±10V
Output Current: ±10 mA
Offset Error: ±0.0045V max
Gain Error: ±0.01%
Update Rate: 100 kHz max, 1.5 Hz min (no minimum with external clock)
Settling Time: 10 µsec max to 1 LSB for full-scale step
Digital Feed-thru: a spike of up to 50 mV may occur on the DAC output
each time the DAC output is updated
Clock Sources: 4 programmable clock sources:
•
•
•
•
The primary acquisition device’s onboard D/A input clock, independent of the scanning input clock

An external D/A input clock, independent of an external scanning input clock
