Note If you use external conversions for single-channel acquisitions, the maximum
sampling rate is 90 kS/s.
DAQCard-1200 User Manual
For multiple-channel data acquisition, observing the data acquisition rates
in Table 4-2 ensures 12-bit accuracy.

Acquisition Mode
Single channel
Multiple channel
The recommended data acquisition rates in Table 4-2 assume that voltage
levels on all the channels included in the scan sequence are within range for
the given gain and are driven by low-impedance sources.
