The new OMB-DAQ-3000 Series offers high-speed, multifunction data acquisition in a low-cost, portable package. The module offers synchronous and concurrent voltage input, temperature input, waveform output, counter input, quadrature encoder input, timer output and digital I/O. Everything needed to begin acquiring, viewing and storing data is included with the OMB-DAQ-3000 Series, including comprehensive software support.
The OMB-DAQ-3000 features a 16-bit/1-MHz A/D converter, 16 analog input channels user- expandable to 64, up to four
16-bit/1-MHz analog outputs, 24 high-speed digital I/O, 2 timer outputs and four 32-bit counters. All analog I/O, digital I/O, and counter/timer I/O can operate synchronously and simultaneously, guaranteeing deterministic I/O among all signal types.
Unique to the OMB-DAQ-3000 is a low-latency, highly deterministic control output mode that operates independent of the PC. In this mode, digital, analog and timer outputs can respond to analog, digital and counter inputs, as fast as 2 µs, at least 1000 times faster than other products that rely on the PC for decision making.
Software
Included with the OMB-DAQ-3000 is new DaqView software, a comprehensive application that enables set-up, data logging and real-time data viewing without requiring any programming skills.

The DaqView software also includes additional features such as direct-to-Excel enhancements, FFT analysis, and statistics.
Also included with the OMB-DAQ-3000 is a complete set of drivers and detailed sample programs for the most popular programming languages and software packages. Driver support includes Visual Basic, C/C++, LabVIEW and DASYLab. DaqCOM provides Windows-based ActiveX/COM-based programming tools for Microsoft Visual Studio and Visual Studio.NET.
Analog Input
The OMB-DAQ-3000 has a 16-bit, 1-MHz A/D coupled with 16 single-ended inputs, 8 differential analog inputs, or 8 differential thermocouple inputs.
Seven software-programmable ranges provide inputs from 10V to ±100 mV full scale. Each channel can be software-configured for a different range, as well as for single-ended or differential bipolar input, or thermocouple input. The hybrid PGIA on the OMB-DAQ-3000 is guaranteed to settle to the specified accuracy while operating at the full 1 Msample/s rate.
Every analog input on the OMB-DAQ-3000 or on the OMB-PDQ30 expansion option can accept a thermocouple (TC) input. Built-in cold-junction sensors are provided for each of the removable screw-terminal connectors, and any TC type can be attached to any channel. When measuring TCs,
the OMB-DAQ-3000 operates in an over-sample mode, where multiple readings taken on each TC channel, digitally filtered, cold­junction compensated and converted to temperature. As a result, channels with TCs attached are measured at a rate 50 Hz to 10 kHz, depending on how much over­sampling is selected. In line-cycle rejection mode, over- sampling occurs during one cycle of either 50 Hz or 60 Hz, providing a high level of 50 Hz or 60 Hz rejection.
Analog Channel Expansion
Adding additional analog input channels for the OMB-DAQ-3000 is easy using the optional OMB-PDQ30 expansion module. The OMB-PDQ30 connects to the OMB-DAQ-3000 by either plugging directly into the expansion connector or via a cable (OMB-CA-96A) if distance is required between the two units.
The OMB-PDQ30 provides an additional 48SE/24DE analog inputs or 24 differential thermocouple inputs, software­configured on a per- channel basis. The total channel capacity with a OMB-PDQ30 attached is 64 single­ended or 32 differential inputs.
Synchronous I/O
The OMB-DAQ-3000 can make analog measurements and read digital and counter inputs, while synchronously generating up to four analog outputs as well as digital pattern outputs. Digital and counter inputs do not affect the overall A/D rate because they use no time slot in the scanning sequencer.
Input Scanning
The OMB-DAQ-3000 has several scanning modes to address a wide variety of applications. A 512­location scan buffer can be loaded by the user with any combination of analog input channels. All analog input channels in the scan buffer are measured sequentially at 1 µs per channel.
The user can also specify that the sequence repeat immediately or repeat after a programmable delay, from 0 to 19 hours, with 20.83 ns resolution.
Output Timing
The digital and analog outputs on the OMB-DAQ-3000 can be updated asynchronously or synchronously in several modes.
In asynchronous mode, digital and analog outputs can be updated before, during or after an analog input sequence. The maximum update rate in this mode is non­deterministic and is entirely dependent on the PC processor speed, the operating system and programming environment.
In synchronous output modes, outputs can be updated continuously from the PC or in response to an input from an analog channel, digital channel or counter channel.
When updated from the PC, the user can specify the rate at which the output is updated in
20.83 ns intervals. Outputs are updated synchronously at a maximum rate of 1 µs.

Low-Latency Setpoint Control Mode
The other synchronous method of output is where either a digital, analog, or timer output is associated with any analog, digital or counter. The state or level of the output is determined by the level or state of an associated input.
Triggering
The OMB-DAQ-3000 supports a full complement of trigger modes to accommodate any measurement application.
Calibration
Every range on the OMB-DAQ-3000 is calibrated from the factory using a digital NIST traceable calibration method. This method works by storing a correction factor for each range on the unit at the time of calibration.
Included with each OMB-DAQ-3000 is DaqCal sofwtare, an easy-to­operate software package that allows the users to calibrate their OMB-DAQ-3000.
Analog Output (OMB-DAQ-3000 and 3001 Only)
Two or four 16-bit, 1-MHz analog output channels are built into the OMB-DAQ-3000 with an output range from -10 to +10V. The maximum rate at which analog outputs can be updated depends on several factors, including the speed of the USB port. Typically, with the A/D operating at full 1 Mreading/s rates, one analog output can be updated continuously from PC memory at 1 MHz, or two analog outputs at 500 kHz or four analog outputs at 250 kHz. If waveform output throughput is critical to your application, contact OMEGA for the most recent update on multi­channel DAC output rates.
In addition, a program can asynchronously output a value to any of the D/As for non-waveform
applications, presuming that the D/A is not already being used in the waveform output mode. Lastly, each of the analog outputs can be used in a control mode, where the output level is dependent on whether an associated analog, digital or counter input is above or below a user-specified limit condition. When used to generate waveforms, the D/As can be clocked in several different modes. Each D/A can be separately selected to be clocked from one of the following sources.
Asynchronous Internal Clock
The on-board programmable clock can generate updates ranging from once every 19 hours to 1 MHz, independent of any acquisition rate.
Synchronous Internal Clock
The rate of analog output update can be synchronized to the acquisition rate derived from 1 MHz to once every 19 hours.
Asynchronous External Clock
A user-supplied external input clock can be used to pace the D/A, entirely independent of analog inputs.
TMQSS-125U-12, $26.95
KMQSS-125U-12, $26.95
Synchronous External Clock
A user-supplied external input clock can pace both the D/A and the analog input.
Digital I/O
Twenty-four TTL-level digital I/O lines are included in the OMB-DAQ-3000. Digital I/O can be programmed in 8-bit groups as either inputs or outputs and they can be scanned in several modes (see Input Scanning). Ports programmed as inputs can be part of the scan group and scanned along with analog input channels, or they can be asynchronously accessed via the PC at any time, including when a scanned acquisition is occurring. Two synchronous modes are supported when scanned along with analog inputs. In one of these modes, digital inputs are scanned at the start of each scan sequence, which means the rate at which they are scanned is dependent on the number of analog input channels and the delay period.
Pattern Generation
Two of the 8-bit ports can be used to generate a 16-bit digital pattern at up to 1 MHz. The digital pattern can be read from PC RAM or a file on the hard disk. Digital pattern generation is clocked in the same four modes as was described with analog output.

Counter Inputs
Four 32-bit counters are built into the OMB-DAQ-3000. Each will accept frequency inputs of up to 20 MHz, and each counter channel can be configured in a variety of modes, including counter, period, pulse width, time between edges, or multi-axis-quadrature encoder. The counters can concurrently monitor time periods, frequencies, pulses, and other event-driven incremental occurrences from encoders, pulse generators, limit switches, proximity switches, and magnetic pick ups. As with all other inputs to the OMB-DAQ-3000, the counter inputs can be read asynchronously under program control, or synchronously as part of an analog and digital scan group based either on an internal programmable timer or on an external clock source. The OMB-DAQ-3000 supports quadrature encoders with up to 2 billion pulses per revolution, 20 MHz input frequencies, and x1, x2, x4 count modes. Encoder input signals must be within
-15 to 15V and the switching threshold is TTL (1.3V).
Timer Outputs
Two 16-bit timer outputs are built into the OMB-DAQ-3000, each capable of generating different square waves with a programmable frequency range from 16 Hz to 1 MHz.
