DAQ Hardware – DAQ Device

• Most DAQ devices have four standard elements: analoginput, analog output, digital I/O, and counters• You can transfer the signal you measure with the DAQ

device to the computer through a variety of different busstructures

DAQ Hardware – Analog Input

The process of measuring an analog signal and transferringthe measurement to a computer for analysis, display, orstorage• An analog signal is a signal that varies continuously• Analog input most commonly measures voltage or current

14

DAQ Hardware – Analog Output

The process of generating analog signals from your computer• Performing digital-to-analog (D/A)

conversions generates analog output• The available analog output types

are voltage and current• To perform a voltage or current

output, a compatible device must beinstalled that can generate thattype of signal

DAQ Hardware – Digital I/O

• Digital signals:− Electrical signals that transfer digital data (on/off, high/low, 1/0)

using a wire− Used to control or measure digital or finite state devices, such

as switches and LEDs− Used to transfer data• program devices• communicate between devices

− Use digital signals as clocks or triggers tocontrol or synchronize other measurements

DAQ Hardware – Counters

• A counter is a digital timing device typically used for eventcounting, frequency measurement, period measurement,position measurement, and pulse generation• A counter has a fixed number it can count to as determined

by the resolution of the counter• For example, a 24-bit counter

can count to:2(Counter Resolution) – 1 = 224 – 1 = 16,777,215

B. Using DAQ Software – Configuration

• Configure and test your DAQ device using the Measurement& Automation Explorer (MAX)

Simulating a DAQ Device

• Using NI-DAQmx simulated devices, you can try NI productsin your application without the hardware• With NI-DAQmx simulated devices, you also can export a

physical device configuration onto a system that does nothave the physical device installed

D. GPIBGPIB (general purposeinterface bus) is astandard interface forcommunication betweeninstruments and controllersfrom various vendors

ni.com/training24

GPIB

• The bus supports one system controller, usually a computer,and up to 14 additional instruments• Controller:

− Defines the communication links− Responds to devices that request service− Sends GPIB commands− Passes/receives control of the bus

E. Serial Port Communication

Serial communication• Transmits data between a computer and a peripheral

device, such as a programmable instrument or anothercomputer• Uses a transmitter to send data one bit at a time over a

single communication line to a receiver• Best method when data transfer rates are low, or you must

transfer data over long distances• Most computers have one or more serial ports, so you do

not need any extra hardware other than a cable
