DataMAX II is a state-of-the-art Windows 2000 based analog
instrumentation recorder designed to replace traditional tape
based data recorders.
Using the latest technology, DataMAX II eliminates the time
consuming methods of the past with a single precision instrument
that will replace a tape recorder, data acquisition system,
and monitoring scopes. From calibration to analysis, a test
now be run in a fraction of the time, with far greater accuracy
than was possible with traditional analog recorders.
Real Time Monitor
DataMAX II has a built-in monitor function. No external scope
or spectrum analyzers are needed to verify the reliability
your recordings! You can choose a combination of Bar Chart,
Digital Voltmeter, Oscilloscope, and Power Spectrum Density
displays to monitor the data and to verify signal accuracy
prior to and during data collection.
DataMAX II includes an individual Analog to Digital Converter
(ADC) per channel. This innovative approach eliminates multiplexing
and guarantees precise time alignment across channels by simultaneously
clocking all the ADCs. In the unlikely event that any one
ADC might falter, neither the operation nor data integrity
of the remaining channels will be affected.
DataMAX II combines precision analog hardware for either
differential voltage or ICP® accelerometers with a multiple
parallel bus structure and uses the most advanced 16 bit
Digital design available. It stores continuous data at unprecedented
speeds: 64 channels at 50 kHz bandwidth, or up to 90
kHz with fewer channels. The DataMAX II multi-speed recorder
will meet your most demanding test and measurement requirements
in lab, field, or flight applications.
Reliable Technology, Dependable Accuracy
DataMAX II incorporates surface mount components, shock mounted
drive bays, high capacity fans, and positive subassembly mechanical
restraints in a shock resistant housing for maximum reliability,
even under adverse conditions. To eliminate distortion and
signal integrity, DataMAX II incorporates a complete analog
front end, including Programmable Gain Amplifiers, brickwall
Anti-Aliasing Filters, and Simultaneous Sampling. The system’s
Programmable Differential Amplifier accepts signals of wide
dynamic range and high frequency, permitting DataMAX II to
static, vibration, acoustic, sonar, and pyro-shock tests. The
programmable Anti-Aliasing Filter is a steep Linear Phase design
whose flat passband and excellent phase characteristics are
perfect for frequency or time domain studies. Based on your
filter selection, DataMAX II will automatically select the
rate to safeguard your data from aliasing signals. No guesswork
or calculation is required!
Click the Record button and DataMAX II is collecting data.
get any easier than that! The DataMAX II Recording Manager
sets the system based on your previous Setup File. It also
monitors the amount of disk storage space and automatically
how much recording time is available for data acquisition.
No calculations are required! When you want to stop testing,
the Stop button. DataMAX II keeps track of each test by saving
your data under the previously assigned file name with an automatically
incremented file extension. No more remembering the file name
or noting it on paper! The power behind this convenience is
DataMAX II provides 3+1 distinct recording modes to suit your
most demanding recording requirements. These are Continuous,
Timed, and Timer modes, each with a Remote Control option.
The Continuous mode acts like a standard tape recorder: push
to start and stop a data collection session. The Timed mode
provides you with a fixed time record duration after you push
the Record button. Timer mode lets you record a fixed duration
after a fixed time interval. This is perfect for quality control
test requirements, where you would like to log data periodically
for the product under test. The Remote Control feature lets
you work in any of the above modes when you supply an external
trigger pulse. Multiple recorders can be locked together to
gather data synchronously on up to 1620 channels at high bandwidth
using a Master/Slave relationship.
Time Monitor and Measure
While the data is being gathered, you can view a combination
of 4 distinct displays to monitor the signal of
up to 8 channels.
To look at all the channels simultaneously, select the Bar
Chart mode which lets you view the signal strength of all
with Peak Hold capability to notify you of any transient activity.
Two time domain displays are provided: the Digital Voltmeter
monitors DC levels, and the Oscilloscope display provides a
graphic view of signal activity.
A Power Spectrum Density display lets you look at the signal
in frequency space for vibration, sonar, and acoustic monitor
applications. In addition, preset Load Displays provide the
ability to quickly scroll through all the channels, eight
a time, to verify signal integrity prior to or during recording,
between cursors, plus RMS and average values.
Access to more sophisticated signal processing is provided
in the DataMAX II Review Manager, allowing high speed file
conversion for industry standard software processing packages.
Playback and Analysis
Data can be played back instantly after recording using the
DataMAX II Review Manager. After selecting a file, use the
Chart, Voltmeter, Oscilloscope, and Power Spectrum Density
display options to play back the data in time or frequency
are available for quick measurements, similar to the real time
To extract the information needed for data analysis, the Review
Manager provides utilities to export files to a wide selection
of advanced signal processing formats, including DADiSP
and MATLAB. In addition, DataMAX II includes the Windows 2000
operating system so you can transfer files over a LAN to server
or workstation for high speed analysis or archiving.
Setup, Configuration, Flexibility, and Backup
To minimize storage space and processing time, DataMAX II provides
a wide selection of sample rates, from 100 samples per second
(SPS) (40 Hz bandwidth) to 200 KSPS (90 kHz bandwidth). Each
input is capable of sampling at 2.5 times the filter cutoff
making DataMAX II ideal for frequency studies. Oversampling
selections of 5 and 10 times the selected filter cutoff are
also available, providing optimal time resolution for applications
such as shock studies.
A pre-test zero can be specified to record the DC offset of
the input channel and can be used to eliminate offsets, similar
to a tare (or zero) function. Acquired data can also be accurately
synchronized to external events using IRIG time options. DataMAX
II records all operating parameters and notations as a permanent
part of the recorded data. These parameters and notes are saved
in a comprehensive parameter file for future reference. If
test needs repeating, any of the files can be loaded so you
won’t have to manually enter the system’s setup
parameters. Also, an ASCII spreadsheet file can be imported
from your master test configuration file to automatically set
up the system.
In addition to the standard hard drive, DataMAX II offers
an archive tape option for permanent storage or to transport
data to different locations. Optional data backup devices,
including DVD, AIT, and other computer peripheral devices
are also available.
DataMAX II introduces a new dimension to the concept of large
scale continuous data collection. Standard features embedded
in DataMAX II are not available in other systems, even as high
cost options. In price and performance nothing compares. If
collecting valid data is critical, you’ll appreciate
the power, ease, and quality that DataMAX II provides.
DataMAX II is based on the Windows 2000 operating system, allowing
you to download data at high speeds for processing or remotely
control data acquisition operations via LAN from a host
server or remote site.
