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

Analog Input:
USB-1608G Series devices
provide 16-bit analog
inputs that are
software-selectable as
16 SE or eight DIFF
inputs. These devices
also support
software-selectable
input ranges of ±10 V,
±5 V, ±2 V, and ±1 V.
Analog Output
(USB-1608GX-2AO only):
The 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 ±10 V. The
outputs default to 0 V
when the host PC is shut
down or suspended, or
when a reset command is
issued to the device.
Trigger Input:
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
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 (+5 V) or
pull-down (0 V) through
a jumper.
Counter Input:
Each 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:
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:
USB-1608G Series devices
provide one external
clock input and one
external clock output
for the analog inputs.
The USB-1608GX-2AO also
has one external clock
input and one external
clock output for the
analog outputs. |
