USB-1608G Series

Analog Input

USB-1608G Series devices provide 16-bit

analog inputs that are software-selectable

as eight DIFF or 16 SE inputs. These devices

also support input ranges of ±10 V, ±5 V,

±2 V, and ±1 V that are software-selectable

per channel.

Analog Output

(USB-1608GX-2AO only)

The USB-1608GX-2AO standard/OEM

board has two 16-bit analog outputs that

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.

Trigger Input

USB-1608G Series devices have an exter-

nal 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

Users can set up repetitive analog input

trigger events. The trigger is automati-

cally re-armed after it is activated. The

A/D trigger count (the number of samples

you want per trigger) is conﬁgurable with

software.

Digital I/O

Eight bidirectional digital I/O lines are

individually conﬁgurable for input or

output. The DIO terminals can detect the

state of any TTL-level input. Users can

conﬁgure for pull-up (+5 V) or pull-down

(0 V) with an onboard jumper.

USB-1608G Series provides eight differential or 16 single-ended analog inputs,

two analog outputs (USB-1608GX-2AO), 8 digital I/O, and one counter input.

Counter Input

Two 32-bit event counters are provided

to count TTL pulses. The counters accept

inputs of up to 20 MHz.

Timer Output

The PWM timer output generates a pulse

output with a programmable frequency

in the range of 0.0149 Hz to 32 MHz. The

timer output parameters are software-

selectable.
