Considerations for using DIFF input mode are discussed in Chapter 3,
Connecting the
Signals. Notice that the signal return path is through the
negative terminal of the instrumentation amplifier and through channel 1,
3, 5, or 7 depending on which channel pair you select.
RSE Input Mode (Eight Channels, Default Setting)
RSE input mode means that all input signals are referenced to a common
ground point that is also tied to the DAQCard-1200 AI ground. The RSE
mode is useful for measuring floating signal sources. Refer to the
Signal Sources
section of Chapter 3,
information. With the RSE configuration, the DAQCard-1200 can monitor
eight different analog input channels.
Considerations for using the RSE mode are discussed in Chapter 3,
Connecting the
Signals. Notice that in RSE mode, the return path of the
signal is through analog ground at the connector through the
AISENSE/AIGND pin.
NRSE Input Mode (Eight Channels)
NRSE input mode means that all signals are referenced to the same
common-mode voltage, which is allowed to float with respect to the analog
ground of the DAQCard-1200. This common mode voltage is subsequently
subtracted out by the instrumentation amplifier. NRSE input mode is useful
when measuring ground-referenced signal sources.
Considerations for using the NRSE configuration are discussed in
Chapter 3,
Connecting the
of the signal is through the negative terminal of the amplifier, available at
the connector through the pin AISENSE/AIGND.
You can set the analog output on the DAQCard-1200 to either bipolar or
unipolar configurations.
