Common Questions

This appendix contains a list of commonly asked questions and their

answers relating to usage and special features of your

NI 6034E/6035E/6036E device.

General Information

What is the DAQ-STC?

The DAQ-STC is the system timing control application-specific

integrated circuit (ASIC) designed by NI and is the backbone of the

NI 6034E/6035E/6036E device. The DAQ-STC contains seven 24-bit

counters and three 16-bit counters. The counters are divided into the

following three groups:

• Analog input—two 24-bit, two 16-bit counters

• Analog output—three 24-bit, one 16-bit counters

• General-purpose counter/timer functions—two 24-bit counters

The groups can be configured independently with timing resolutions of

50 ns or 10 µs. With the DAQ-STC, you can interconnect a wide variety of

internal timing signals to other internal blocks. The interconnection scheme

is quite flexible and completely software configurable. New capabilities

such as buffered pulse generation, equivalent time sampling, and seamless

changing of the sampling rate are possible.

What does sampling rate mean to me?

It means that this is the fastest you can acquire data on your

NI 6034E/6035E/6036E device and still achieve accurate results. For

example, these devices have a sampling rate of 200 kS/s. This sampling rate

is aggregate: one channel at 200 kS/s or two channels at 100 kS/s per

channel illustrates the relationship.
