Analog Input Signal Connections
The AI signals are ACH<0..15>, AISENSE, and AIGND. The
ACH<0..15> signals connect to the 16 AI channels of the NI 6052E.
In single-ended modes, signals connected to ACH<0..15> are routed
to the positive input of the PGIA. In DIFF mode, signals connected to
ACH<0..7> are routed to the positive input of the PGIA, and signals
connected to ACH<8..15> are routed to the negative input of the PGIA.
Caution Exceeding the differential and common-mode input ranges distorts the input
signals. Exceeding the maximum input voltage rating can damage the device and the
computer. NI is
not liable for any damage resulting from such signal connections.
The maximum input voltage ratings are listed in the Protection column of Table 4-3.
