Averaged measurements assume averaging of 100 single-channel readings.
Each PCI-DAS6013 and PCI-DAS6014 is tested at the factory to assure the board's overall error does not
exceed accuracy limits described in Table 1.

System throughput

Condition
1. Single channel, single input range
2. Multiple channel, single input range
3. Single channel, multiple input ranges
For conditions 1-2 above, specified accuracy is maintained at rated throughput. Condition 3
Note 2:
applies a calibration coefficient which corresponds to the range value selected in
This coefficient remains unchanged throughout the scan. Increased settling times may occur
during gain-switching operations.

Settling time

Settling time is defined as the time required for a channel to settle to within a specified accuracy in response to
a full-scale (FS) step. Two channels are scanned at the specified rate. A –FS DC signal is presented to
channel 1; a +FS DC signal is presented to channel 0.
