Based on Measurement Computing's popular USB-1616HS series, the USB-1616HS-BNC provides the added security and convenience of BNC connectors.

Unique to the USB-1616HS Series is a low-latency, highly deterministic control output mode that operates independently 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 1,000 times faster than other USB DAQ products that rely on the PC for decision making.

The USB-1616HS-BNC offers extensive trigger options, ranging from an analog trigger with 1 µs max latency, to multi-channel triggering, where any combination of analog, digital, and counter input channels can be combined to initiate the trigger. Other trigger modes include digital pattern, level, edge, inside/outside window, and pre- and post-trigger.

USB-1616HS-BNC features:

Analog Inputs via BNC connectors

• 16 differential analog inputs
• 16-bit resolution
• 1 MS/s throughput rate
• 7 programmable input ranges from ±100 mV to ±10 V, full scale
• Over-sampling mode, including line-cycle rejection for low-level voltage measurements, even in the presence of AC power line noise

Analog Outputs and Digital I/O via 37-pin DSUB female connector

• Two 16-bit, 1 MS/s analog outputs
• 16 digital I/O bits with a 4 MHz sample/update rate
• 4 counter inputs capable of measuring frequency, period, pulse width, or quadrature encoders up to 20 MS/s
• 2 timer outputs

All analog inputs, analog outputs, digital I/O and counter/timer I/O can occur synchronously, resulting in precise time correlation among all I/O. Low latency control outputs are capable of responding to inputs in as fast as 2 µs.

The USB-1616HS-BNC ships with an impressive array of software, including TracerDAQ, a full-featured data logging, viewing, and analysis application; Universal Library; UL for LabVIEW®; and InstaCal installation, calibration, and test utility—powerful software solutions for programmers and non-programmers alike.

Makes temperature measurement easy! The USB-TEMP provides 8 temperature inputs and supports all of the common temperature sensors.It supports measurements from thermocouples, RTDs, thermistors and semiconductor temperature sensors. Each channel can monitor any of the supported input types allowing you to mix and match the sensor to measurement without needing additional signal conditioning.

Powerful, accurate, great value: The internal measurement electronics accuracy vastly exceeds the accuracy specifications of the temperature sensors so you are guaranteed to record the most accurate data possible.

Free software included: Of course the USB-TEMP comes complete with software to solve all your temperature measurement problems. Everything from installation, calibration, test, data logging, strip charting, graphical programming, Visual Studio programming and LabVIEW VIs.

The National Instruments USB-621x devices are bus-powered M Series multifunction data acquisition (DAQ) modules optimized for superior accuracy at fast sampling rates. They feature up to 32 analog inputs; 250 kS/s single-channel sampling rate; two analog outputs; up to 8 digital input lines; up to 8 digital output lines; four programmable input ranges (±0.2 V to ±10 V) per channel; digital triggering; and two counter/timers. NI USB-6215 and NI USB-6218 also feature isolation for improved measurement accuracy and safety.

The NI USB-621x modules are designed specifically for mobile or space-constrained applications. Plug-and-play installation minimizes configuration and set-up time, while direct screw-terminal connectivity keeps costs down and simplifies signal connections. Bus-powered from USB means that users can discard unecessary external power supplies. NI-DAQmx driver and measurement services software provides easy-to-use configuration and programming interfaces with features such as DAQ Assistant to help reduce development time.

The USB-1616HS delivers outstanding performance with synchronous analog, digital, and frequency I/O in one compact package. It has a unique, low-latency control output mode, whereby any input—analog, digital, or counter, can control an output—digital, analog, or timer, based on pre-defined limits, including hysteresis. The outputs are controlled directly from the USB-1616HS series module, and do not require PC intervention. This results in response times that are measured in microseconds instead of milliseconds

The USB-1616HS offers extensive trigger options, ranging from analog trigger with 1 µs max latency, to multichannel triggering, where any combination of analog, digital, and counter input channels can be combined to initiate the trigger. Other trigger modes include digital pattern, level, edge, inside/outside window, and pre- and post-trigger.
