CCommon Questions
This appendix contains a list of commonly asked questions and their
answersr elating to usage and special features of the NI 6013/6014.
General Information
Whati s the DAQ-STC?
The DAQ-STCis the system timing control application-specific
integratedcircuit (ASIC) designed by NI and is the backbone of the
NI6 013/6014. The DAQ-STCcontains seven 24-bit counters and three
16-bitc ounters. The counters are dividedinto the following three groups:
•AI—two24-bi t, two16-bit co unters
•AO—three 24-bit, one 16-bit counters
•General-purpose counter/timer functions—two 24-bit counters
The groups can be configuredin dependently with timing resolutions of
50 ns or 10 µs. Withthe DAQ-STC, you can interconnect a wide variety of
internaltiming signals to other internal blocks. The interconnection scheme
is quite flexible and completely software configurable. New capabilities
suchas buffered pulse generation, equivalent time sampling, and seamless
changing of the sampling rate are possible.
Whatdoes samplingrate mean to me?
Sampling rate is the fastest you can acquire data on the NI 6013/6014 and
stilla chieveaccurate results. For example, these devices have a sampling
rate of 200 kS/s. This sampling rate is aggregate:one channel at 200 kS/s
ort wochann els at 100 kS/s per channel illustrates the relationship.
Whattype o f 5 V protectiondoes the NI 6013/6014 have?
The NI 6013/6014 has 5 V lines equipped with a self-resetting 1 A fuse.
