The USB-1616FS features simultaneous sampling of 16 single-ended analog inputs, 8 DIO
lines, and a 32-bit event counter

Overview
The USB-1616FS provides 16 simultaneously sampled 16-bit analog inputs withsample rates up to 50 kS/s per channel, continuous throughputs of 150 kS/s, and32 kilosample bursts up to 200 kS/s. The device also provides one 32-bit counterand 8 digital I/O lines.
The USB-1616FS design features a heavy-duty chassis with integrated mounting
slots, ensuring that the device is rugged enough for any DAQ application.
The combination of the USB-1616FS and Measurement Computing DAQ software
suite gives you a complete data acquisition solution that will have you taking
measurements in minutes. The device is fully USB plug and play. An external
power adapter is included.

Analog Input

Sample Rates

The USB-1616FS provides 16 single-ended
analog inputs. A channel gain queue feature lets users set up a scan list to sample
up to 16 different analog input channels
at different gains (ranges).

Simultaneous Sampling
Each analog input channel has a dedicated16-bit A/D converter for true simultaneous
sampling of all 16 inputs.

With hardware paced mode, the maximum throughput rate is 50 kS/s for one
channel, or 9.5 kS/s per channel for
all channels.
With burst scan mode, the maximum
throughput rate is 50 kS/s per channel for
one, two, or three channels, and 16.5 kS/s
per channel for all 16 channels.

Digital I/O
Eight digital IO lines are independently
selectable as input or output. All digital
lines are pulled up by default with a47 kΩ resistor.

1Counter Input
The 32-bit event counter accepts frequency inputs up to 1 MHz, and increments
when the TTL level transitions from lowto high.

Trigger Input
The USB-1616FS has an external digitaltrigger input. The trigger mode is configurable with software for rising (default) orfalling edge.

External Clock I/O
A bidirectional SYNC (synchronization)
control line can be configured as either
input or output.
Configure as an external clock input toexternally clock A/D conversions, or as
an output to synchronize with a second USB-1616FS and acquire data from32 channels.

Calibration

PowerUSB-1616FS devices are factory-calibrated using a NIST-traceablecalibration process. Specifications are guaranteed for one year.
For calibration beyond one year, return the device to the factoryfor recalibration.

The USB-1616FS receives power from the +9 V unregulated
power supply that is shipped with the device. Power and USB
connectors let you power and control multiple MCC USB Series
products from one external power source and one USB port ina daisy chain fashion.

Multiple board throughput

An integral USB hub allows up to four USB-1616FS devices to be daisy chainedand connected to a single USB port on the host computer. Revision F and later
are compatible with USB 3.0. Older revisions can be daisy chained from a Revision F device attached to a USB 3.0 adapter. Refer to “Board Revision” below forrevision information.
Data transfer over the USB bus is CPU intensive and system dependent. Multiple
board performance is limited by an overall aggregate sample rate. The maximum
throughput is the number of samples taken per second, regardless of the numberof channels sampled or number of devices installed. The maximum sample rateof any one channel is limited to 50 kS/s.
For example, if the maximum throughput is 150,000 S/s, you may sample 20 channels at 7.5 kS/s, 30 channels at 5 kS/s, 40 channels at 3.75 kS/s, and so on.
