The OMB-LOGBOOK-300 is a
portable data acquisition system
that can be used for remote,
portable and unattended
operation. It is also operational with
a PC attached.
The OMB-LOGBOOK-300
combines on-board intelligence and
a large capacity PC-Card removable
memory with the
industry’s easiest and most
powerful data logging software. Its
16-bit, 100-kHz A/D and
triggering capabilities make
it ideal for collecting high
and low speed phenomena.
A comprehensive array of signal
conditioning expansion cards and
modules are offered that allow the
OMB-LOGBOOK-300 to take
measurements from
virtually any transducer, from
thermocouples to
accelerometers.
The OMB-LOGBOOK-300 data
acquisition system includes
LogView graphical display and
acquisition software, which allows
for fast setup and easy use, with
no programming required. LogView
software uses a spreadsheet
metaphor rather than programming
to configure the channels and the
acquisition parameters.
Operating Modes
Once an acquisition configuration has
been developed, it can be downloaded
to a PC-Card for transport to a
remote OMB-LOGBOOK-300, or it
can be directly downloaded to an
attached OMB-LOGBOOK-300 via
the serial or parallel port. The
OMB-LOGBOOK-300 can be used
in stand-alone mode where no PC is
present, or it can be linked to a PC
via a serial or parallel port for
interactive data collection.
A PC running LogView can interact
with an attached OMB-LOGBOOK-300
at any time, both during the setup
and/or while the acquisition is taking
place. To observe acquired data,
channel values can be displayed in
any or all of LogView’s many realtime
indicators.
SOPHISTICATED
TRIGGERING AND
SAMPLING
Along with simple triggering and
continuous data logging, the
OMB-LOGBOOK-300 can be
configured to intelligently collect only
the data you want. For sophisticated
triggering, a calculated channel can
be specified as the trigger or the stop
event. A calculated channel can
describe virtually any combination of
channel conditions. For example, you
can develop a calculated channel
called TRIG and specify it as the
trigger channel. If the channel’s
equation is TRIG = (Temp1 - Temp2)
> 50.0, the data collection process
will be triggered when the difference
between the two temperature
channels is above 50.0 degrees.
CHANNEL-SCANNING
FLEXIBILITY
The OMB-LOGBOOK-300 offers
a scan sequencer that allows you to
select each channel and associated
input amplifier gain at random. The
sequencer circuitry circumvents a
major limitation encountered with
many plug-in data acquisition
boards–a drastic reduction in the
scan rate for external expansion
channels. All inputs, including analog,
digital, counter, and calculated
channels, are sampled at 100 KHz
allowing time correlation of mixed
signals. The OMB-LOGBOOK-300
permits each scan group to be
repeated immediately or at
programmable intervals for up to
10 hours. Within each scan group,
consecutive channels are measured
at a fixed 10 µs/channel rate. If data
collection is only desired under
specific conditions, an appropriate
trigger can be specified. When using
a trigger to start the acquisition, a
pre-trigger count can be supplied so
that information just before the
trigger can be collected and saved.
The stop event definition specifies
when the data collection activity
should end. A wide variety of trigger
sources and stop event choices
provides a high degree of exception
capture flexibility. For example, the
OMB-LOGBOOK-300 can be
configured to capture all data from
all input channels for as long as the
temperature difference between
channels 1 & 2 is greater than
50 degrees.
Channel Expansion
The system can be expanded using
a comprehensive line of signal
conditioning and expansion options.
The OMB-LOGBOOK-300 is
expandable to up to 256 analog
inputs and 208 digital I/O lines.
Economical signal conditioning
hardware includes thermocouple,
RTD, high gain, high voltage,
current, strain gage, accelerometer,
frequency, filter, and simultaneous
sample and hold.
All of the channels in an
OMB-LOGBOOK-300 system,
including the base I/O and
expansion channels, are sampled
synchronously, providing time
correlation of all collected data.
The OMB-LOGBOOK-300
provides both internal and
external pacer clock control so
that scans can be collected using
the OMB-LOGBOOK-300’s internal
programmable oscillator or an
externally supplied custom
frequency clock.
Unlike many multiplexed input
data loggers, the OMB-LOGBOOK-
300’s base analog input channels
have a unique buffer-amplifier-perchannel
design to eliminate noise
and channel-to-channel crosstalk
while maximizing accuracy - even
with high-impedance transducers.
For ease of use, all of the
OMB-LOGBOOK-300’s settings
are software controlled, eliminating
the need for switches and jumpers.
Each channel is digitally calibrated,
eliminating drift-prone
potentiometers.
Unlike many plug-in board
data acquisition systems, the
OMB-LogBook-300’s
programmable channel/gain
sequencer scans expansion
channels at the same rate as
its on-board channels. For this
reason, the OMB-LOGBOOK-300
is well suited for test applications
that require both high channelcount
and high speed.
LOGVIEW SOFTWARE
SIMPLFIES SETUP
LogView uses a series of
spreadsheets to allow simple setup
and display of all channel parameters.
No auxiliary dialog boxes, configurable
block diagrams, or programming
methodologies are employed.
Simply select the appropriate cell,
choose the desired setting from the
dropdown list, and the parameter is
set. To apply the same setting to
multiple channels, select a block of
cells within a column and use the
spreadsheet’s fill-down feature.
After the channels and the acquisition
parameters have been configured,
download the configuration to a
PC-Card in one of your PC’s
sockets, or send the configuration
directly to the OMB-LOGBOOK-300
via the serial or parallel port. When
a PC-Card is used to transport the
acquisition configuration to a remote
OMB-LOGBOOK-300, inserting
the card into one of its sockets
signals the OMB-LOGBOOK-300
to read and execute the new
acquisition configuration.
Once the channel configuration
parameters have been downloaded to
the OMB-LOGBOOK-300, LogView
can display the channel values of a
connected OMB-LOGBOOK-300 in
real time, both before and during an
acquisition. LogView conveniently
displays channel values in the
channel configuration spreadsheet
or in real-time bargraphs, analog
meters, and digital indicators.
SPREADSHEETS
MAKE IT SIMPLE
All of the parameters for the analog
I/O, digital I/O, frequency and
calculated channels can be viewed
and adjusted through LogView’s
unique spreadsheet interface.
The spreadsheets make it
possible to see and adjust the
parameters of many channels
concurrently, unlike typical data
parameters of many channels
concurrently, unlike typical data
logging software that requires
channels to be set up one at a time
through auxiliary dialog boxes.
Channel parameters are
independent of one another.
Channel parameters include:
- Turning the channel on or off
- Programmable input range for
analog input channels
- Scaling and offset for
engineering units conversion
- Any or all of 4 timebases to
log the channel
- The equation that defines the
calculated channel
- The physical output channel
to direct a calculated or input
channel
- Special parameters specific
to certain signal conditioning
modules
All inputs including analog, digital,
frequency and calculated channels
are collected synchronously so that
data from widely dissimilar inputs
can be correlated in time.
Within the analog spreadsheet, an
offset adjustment or 2-point
calibration can be performed
for each channel. This function
compensates for inaccuracies
in signal conditioning circuitry and
sensors.
