, which is the input
protection resistance.
Calibration
Circuitry Functional. Both analog
input and analog output can
be fully calibrated. Partially functional. Draws
negligible power.
CALDACs retain values
and may be loaded, but
adjustments will not be
detected in analog circuitry,
which is powered off.
Digital I/O Functional. Protected from
-0.5 to 5.5 V. Functional. Protected from
-0.5 to 5.5 V.
Counters Functional. Initialize to
undefined states. Individual
counters of the DAQ-STC
must be fully programmed
before use. Protected from
-0.5 to 5.5 V. Functional. Initialize to
undefined states. Individual
counters of the DAQ-STC
must be fully programmed
before use. Protected from
-0.5 to 5.5 V.
