The DaqTemp data acquisition systemprovides a total hardware/­software/signal
conditioning solution for high-accuracy
temperature, voltage, frequency, and pulse
counting measurements, plus digital I/O
and analog output.
DaqTemp hardware is comprised of aplug-and-play PCI board, 3 ft. cable,
and screw terminal/signal conditioning
pod. Cold-junction compensation isbuilt-in to the DaqTemp, which provides
precise thermocouple measurements, withchannel-to-channel variation and noiseless than 0.2 ˚C, and accuracy better than
1.0 ˚C. A separate low-noise amplifier
per TC channel allows for these exact
measurements. DaqTemp is available with

Measurement Computing

DaqTemp includes a full suiteof software including DaqView
Out-of-the-Box software

14 thermocouple input ­channels. All power
for the DaqTemp is derived from the PC;
therefore no external power supplies ortransformers are needed.
In addition to thermocouple inputs,­DaqTemp also provides 7 differential v­ oltage
input channels that offer 16-bit resolution
and 13 programmable full-scale input ranges
from ±156 mV to ±10V. The 4 frequency
input channels can measure frequency or
count pulses up to 10 MHz. Two timer output
channels are capable of generating squarewave outputs up to 1 MHz. Twenty-four
digital I/O lines are also included, which
can be programmed in 8-bit groups as either
inputs or outputs.
All inputs, including thermocouple inputs,voltage, frequency, and digital, can be synchronously scanned up to 200K readings/s,
which provides accurate time correlation between all inputs. The 16-bit/100 kHz analog
outputs can be used to generate waveforms
with a virtually infinite ­waveform output
length from PC memory.

1All inputs and outputs are accessed via
convenient screw terminals located on thesignal conditioning pod. The cover of thesignal conditioning pod is easily removed
to gain access to the screw ­terminals for
signal connections.
The DaqTemp is supplied with DaqView
Out-of-the-Box software, which enables you
to set up your acquisition, view the results
in real time, and save the data to disk —all without any programming. DaqView’s
intuitive graphical user interface is aseasy to use as a spreadsheet, yet powerfulenough for most data acquisition applications. DaqView performs all thermocouple
linearization and conversion of readings
to engineering units. You can trigger anacquisition on temperature level, digital
input, voltage level, frequency input,
software command, and more. Real-timegraphical output can be any combinationof digital readouts, scrolling strip-charts,
bar graphs, or dials. Every channel canbe displayed in any or all of the available
real-time display indicators.

Triggering

Frequency/Pulse Counters

Trigger Sources: 6, individually selectable for startingand stopping an acquisition. Stop acquisition canoccur on a different trigger source other than startacquisition, and can be triggered via modes 2, 4, 5,
or 6. Pre-trigger is supported with fixed or variable
pre-trigger periods.
1. Single-Channel Analog Hardware Trigger		Latency: 5 µs max
2. Single-Channel Analog Software Trigger		Latency: One scan period max
3. Single-Channel Digital Trigger		Latency: 5 µs max
4. Digital Pattern Triggering		Latency: One scan period max
5. Counter/Totalizer Triggering		Latency: One scan period, max
6. Software Triggering		 Trigger can be initiated under program control.

Counter inputs can be scanned synchronously alongwith voltage, TC, and digital scanned inputs, based
either on internal programmable timer or an external
clock source. Bus Mastering DMA provides CPU andsystem-independent data transfers, ensuring dataacquisition performance irrespective of other system
activities. Counters can be configured to clear when
read, or to totalize and clear under program control.
Channels: 4 x 16-bit; cascadable as 2 x 32-bit
Frequency Measurement Rate: 10 MHz max
Input Signal Range: -15V to +15V
Trigger Level: TTL
Minimum Pulse Width: 50 ns high, 50 ns low

Analog Output
Four analog output channels can be updated synchronously relative to scanned inputs, and clocked fromeither an internal onboard clock, or an external
clock source. Analog outputs can also be updated
asynchronously, independent of any other scanning in the system. Bus Mastering DMA provides
CPU and system-independent data transfers. Thisfeature ensures accurate outputs that are irrespective of other system activities. Streaming from disk
or memory is supported, which allows continuous,
nearly infinite length, waveform outputs (limited
only by available PC system resources).
