Description

The OM-USB-1608FS Series consists of the following low-cost, analog and digital I/O modules:

    • OM-USB 1608FS
    • OM-USB-1608FS-PLUS

These modules provide eight single-ended (SE), simultaneous-sampling 16-bit analog inputs, eight DIO, one event counter, one external digital trigger input, and one bidirectional external clock. Everything you need to begin acquiring, viewing, and storing data is included with each OM-USB-1608FS Series module, including comprehensive software support.

SOFTWARE
OM-USB-1608FS Series modules ship with an impressive array of software, including the new TracerDAQ®, a full-featured, 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 Vls and example programs compatible with 32-bit and 64-bit
LabVIEW v8.5 through 2013) and InstaCal™ 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-1608FS Series 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 acquired 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. A comparison of some of the features included in TracerDAQ vs. TracerDAQ PRO is shown on the PDF.

ANALOG INPUT
Both modules provide eight single-ended (SE) 16-bit analog input channels with a dedicated A/D converter per channel for simultaneous sampling. The devices offer software-selectable analog input ranges for ±10V, ±5V, ±2V, and ±1V.

SAMPLING RATE
OM-USB-1608FS Series modules offer the following sampling rates when scanning continuously to computer memory (hardware-paced mode):
• OM-USB-1608FS-PLUS - Total rate of 400 kS/s divided by the number of channels sampled; maximum rate of 100 kS/s per channel.
• OM-USB-1608FS - Total rate of 100 kS/s divided by the number of channels sampled; maximum rate of 50 kS/s per channel.

SIMULTANEOUS SAMPLING
In hardware paced mode, both modules can acquire data from up to eight channels simultaneously. The analog data is continuously acquired, converted to digital values, temporarily stored in the onboard FIFO buffer, and periodically uploaded to the computer.

CHANNEL-GAIN QUEUE
The channel-gain queue lets you configure a list of channels and gains for each scan. Each channel can have a different gain setting. The gain settings are stored in a channel-gain queue list that is written to local memory on the device. The channel-gain queue list for both modules can contain up to eight unique channels. On the OM-USB-1608FS, the channels must be consecutive and listed in increasing order. On the OM-USB-1608FS-PLUS, the channels can be nonconsecutive, but still must be listed in increasing order.

DIGITAL I/O
Both modules provide eight digital I/O connections. Each digital channel is individually-configurable for input or output. When configured for input, you can use the digital I/O terminals to detect the state of any TTL level input. On the OM-USB-1608FS-PLUS, the digital I/O channels are high-drive (24 mA) connections.

COUNTER INPUT
The OM-USB-1608FS-PLUS has a 32-bit event counter that can accept a signal up to 1 MHz. The internal counter increments when the TTL levels transition from low to high.

EXTERNAL CLOCK I/O
Each OM-USB-1608FS Series module has a bidirectional external clock terminal. When configured for input, A/D conversions can be paced by an external source. The OM-USB-1608FS supports TTL-level input signals up to 50 kHz. The OM-USB-1608FS-PLUS supports TTL-level input signals up to 100 kHz. When configured for output, both devices can pace A/D conversions on a second device and acquire data from all input channels simultaneously.

TRIGGER INPUT
OM-USB-1608FS Series modules provide an external digital trigger input. The OM-USB-1608FS trigger mode is edge sensitive and software-selectable for rising or falling edge. The OM-USB-1608FS-PLUS trigger mode is edge or level sensitive. Edge sensitive is software-selectable for rising or falling edge. Level sensitive is softwareselectable for high or low level.

CALIBRATION
Each OM-USB-1608FS Series module ships fully calibrated and can be re-calibrated at the factory. The OM-USB-1608FS also supports user calibration.
