QuickDAQ

Ready-to-Measure Data Acquisition Software(including Advanced FFT Analysis Functions for Powerful Measurement & Analysis)

Overview
QuickDAQ allows you to acquire and display
measurement data from all Data Translation USB andEthernet devices that support analog input streaming.
Combine QuickDAQ with Data Translation hardware toacquire data, record data to disk, display the results inboth a plot and digital display, and read a recorded data
file.
Be productive right out of the box with this powerfuldata logging software. Two additional options can bepurchased to add FFT analysis capabilities to the basepackage to provide the ultimate in measurement andanalysis capabilities for sound and vibration and otherapplications. For further analysis, export the data toother applications like Microsoft Excel®.

QuickDAQ ready-to-measure application software, combinedwith Data Translation hardware, is a powerful data logger.
Optional FFT Analysis functions can be purchased to extend
the capabilities of the base package to provide powerfulmeasurement and analysis capability for sound and vibrationand other applications.

QuickDAQ Base Version

FFT & Advanced FFT Analysis Options

The base version of QuickDAQ is free-of-charge andallows users to acquire and analyze data from all DataTranslation USB and Ethernet devices, except the DT9841
Series, DT9817, DT9835, and DT9853/54. Using the baseversion of QuickDAQ, users can perform the following
functions:

QuickDAQ with FFT Analysis and Advanced FFT Analysisoptions adds real-time analysis features to Data
Translation modules. The add-ons feature tools to acquirecontinuous and triggered data, record data to disk, reada recorded data file, analyze the acquired data using
single FFT and two-channel FFT functions, and produce
a variety of output stimuli for modal analysis testing.
The software is navigated through a series of easy-to-use
configuration windows, allowing flexible selection of
the desired acquisition, processing, plotting and display
parameters.

Dynamic Performance Functions Provided with the Advanced FFT Analysis Option

This function returns a value in dB units representing thelevel of the main signal component relative to the full scale
voltage of the channel.

This function returns a value in dB units representing thelevel of the main signal component relative to the total noise(i.e. harmonics are not included).

This function returns a value in dB units representing thelevel of the main signal component relative to the totalnoise, including harmonics.

This function returns a value in dB units representing
the level of the full scale range to the greatest noise or
distortion component.

This function returns a value in dB units and percent (%)
representing the level of the harmonic distortion of the first
5 harmonics relative to the main signal component.

This function returns a value in bits representing the qualityof a digitized signal. The input signal is typically sinusoidal
and should be near full scale to properly characterize the ADand/or system.

Configuration Windows
The base version of QuickDAQ provides a Data Loggerinterface. The FFT Analysis and Advanced FFT Analysis
options provide an additional FFT Analyzer interface;
users of these options can switch between interfaces asneeded.

Configure Devices Window
The elements of the Configure Devices window dependon the connected device. Selections may include: enablechannels for acquisition, specify a meaningful namefor each channel, select an input range (on devices
that support multiple ranges), choose sensor type,engineering unit, AC/DC coupling and current source (fordevices with IEPE support), etc.

Configuration windows of the FFT Analyzer interface.

The Freq tab (in the FFT Analyzer interface only)
allows users to set up the maximum frequency to beanalyzed, the FFT size, and other parameters that apply
to the analog input subsystem, such as the channel
configuration (single-ended or differential), input voltage
range, temperature units to use when converting voltage
data to temperature, and/or the filter type.

Additional configuration and calibration wizards areincluded to perform shunt calibration and offset nullingfor strain gage or bridge-based sensors.
The Recording tab allows
users to set up the namefor the data file, and enable
or disable continuous
acquisition. In the Data
Logger interface, users canalso specify the acquisition
duration and x-axis span. In
the FFT Analyzer interface,
users can also specify howmany records to acquire,process, and average.

The Trigger tab (in the FFT Analyzer interface only)
allows users to specify the trigger source that starts
acquisition and the trigger mode.
The Window tab (in the FFT Analyzer interface only)
allows users to specify a windowing function to apply to
the FFT channel to reduce spectral leakage errors.
The Output tab allows users to set up the parametersthat apply to the analog output
subsystem. Define the type ofwaveform to output (fixed,sweep, or noise), and all theparameters that apply to thatwaveform type, including thesignal or noise type, sweep mode,
whether the signal is output
continuously or as a burst, thefrequency of the output signal,
whether to ramp up or down,
and how to start the operation.
This tab is only available if theconnected device supports analog
output operations.

The Acquisition tab (in theData Logger interface only)
allows users to set up theparameters that apply tothe analog input subsystem,
including the per channel
sampling frequency of the device,
the trigger source that starts
the acquisition, the channel
configuration (single-ended orConfigurationdifferential), input voltage range, windows of the Data
Logger interface
the temperature units to use
when converting voltage data totemperature, and/or the filter type.
