The OM-USB-1608G Series devices are low-cost, high-speed, analog and digital I/O USB devices. All of these devices offer up to eight differential (DIFF) or 16 single-ended (SE) analog inputs, up to eight digital I/O channels, two counter inputs, and one timer output.

The OM-USB-1608GX-2AO offers two, 16-bit analog output channels with DAC rates up to 500 kS/s.

Everything you need to begin acquiring, viewing, and storing data is included with each OM-USB-1608G Series device, including comprehensive software support.

Analog Model Analog Inputs Sampling Rate Outputs Digital I/O Counters

OM-USB-1608G 16 SE/8 DIFF Up to 250 kS/s 0 8 2

OM-USB-1608GX 16 SE/8 DIFF Up to 500 kS/s 0 8 2 OM-USB-1608GX-2AO 16 SE/8 DIFF Up to 500 kS/s 2 8 2

Analog Input

OM-USB-1608G Series devices provide 16-bit analog inputs that are software-selectable as 16 SE or eight DIFF inputs. These devices also support input ranges of ±10V, ±5V, ±2V, and ±1V that are software-selectable per channel

Analog Output

(OM-USB-1608GX-2AO only) The OM-USB-1608GX-2AO has two

16-bit analog outputs. Both outputs can be updated at a rate of 250 kS/s per channel; one output can be updated at a rate of 500 kS/s. The output range is ﬁxed at ±10V. The outputs default to 0V when the host PC is shut down or suspended, or when a reset command is issued to the device.

Trigger Input

OM-USB-1608G Series devices have an external digital trigger input. The trigger mode is software-selectable for edge or level sensitive mode. You can conﬁgure edge-sensitive mode for either rising or falling edge. In level sensitive mode, you can conﬁgure for either high or low level. The default setting at power up is edge-sensitive, rising edge.

Retrigger Mode: In retrigger mode, you can set up repetitive analog input trigger events. The trigger is automatically re-armed after it is activated. Use software to set the A/D trigger count (the number of samples you want per trigger).

Digital I/O

Eight bidirectional digital I/O connections are included with OM-USB-1608G Series devices. Each digital channel is individually conﬁgurable for input or output. The digital I/O terminals can detect the state of any TTL-level input. You can conﬁgure for pull-up (+5V) or pulldown (0V) through a jumper.

Counter Input

Each OM-USB-1608G Series device includes two 32-bit event counters for counting TTL pulses. The counters accept frequency inputs of up to 20 MHz.

Timer Output

OM-USB-1608G Series devices have a PWM timer output that can generate a pulse output with a programmable frequency in the range of 0.0149 Hz to 32 MHz. The timer output parameters are software-selectable.

External Clock I/O

OM-USB-1608G Series devices provide one external clock input and one external clock output for the analog inputs. The OM-USB-1608GX-2AO also has one external clock input and one external clock output for the analog outputs.

Software

The OM-USB-1608G modules ship with an impressive array of software, including the new TracerDAQ®, a fullfeatured, out-of-the-box data logging, viewing, and analysis application.

Driver support and detailed example programs are included for Universal Library programming libraries for Microsoft® Visual Studio® programming languages, and other languages, including DASYLab®, and ULx for NI LabVIEW® (comprehensive library of VIs and example programs compatible with 32-bit and 64-bit LabVIEW v8.5 through 2012) and InstaCalTM installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows® XP (32-bit only) and VISTA/7/8 (32-bit and 64-bit) operating systems.

The OM-USB-1608G data acquisition modules are supplied with TracerDAQ software which is a collection of four virtual instrument applications used to graphically display and store input data and generate output signals:

• Strip Chart—Log and graph values

acquire from analog inputs, digital inputs, temperature inputs and counter inputs

• Oscilloscope—Display values

acquired from analog inputs

• Function Generator—Generate

waveforms for analog outputs

• Rate Generator—Generate

waveforms for counter outputs

TracerDAQ PRO is an enhanced version of TracerDAQ and is available as a purchased upgrade (SWD-TRACERDAQ-PRO). A comparison of some of the features included in TracerDAQ vs TracerDAQ PRO is shown below.
