Analog Input
Refer to one of the following sections, depending on you r device:
• Analog Input on MIO X Series Devices—NI 632x/634x/6351/
6353/6361/6363 devices can be configured for single-ended and
differential analog input measurements.
• Analog Input on Simultaneous MIO X Series Devices—NI 6356/
6358/6366/6368 devices can be configured for differential analog
input simultaneous sampled measurements.
Analog Input on MIO X Series Devices
Figure 4-1 shows the analog input circuitry of MIO X Series devices.
Figure 4-1. MIO X Series Analog Input Circuitry
The main blocks featured in the MIO X Series device analog input circuitry
are as follows:
• I/O Connector—You can connect analog input signals to the MIO
X Series device through the I/O connector. The proper way to connect
analog input signals depends on the analog input ground-reference
settings, described in the Analog Input Ground-Reference Settings
section. Also refer to Appendix A, Device-Specific Information, for
device I/O connector pinouts.
