High-Speed Multifunction DAQ with Synchronous I/O

Analog Input

The USB-1602HS/USB-1602HS-2AO has

two analog inputs and the USB-1604HS/

USB-1604HS-2AO has four. Each input

has a dedicated 16-bit ADC that provides

true simultaneous sampling per channel.

The input range is software-selectable for

±10 V, ±2.5 V, or ±500 mV. The sample

rate is 2 MS/s for the USB-1602HS and

USB-1602HS-2AO, and 1.33 MS/s for the

USB-1604HS and USB-1604HS-2AO, per

channel. Users can pace analog input

operations with the internal A/D pacer

clock or with an external clock.

Analog Output

USB-1602HS-2AO and USB-1604HS-2AO

provide two independent, 16-bit, analog

outputs. Each analog output can continu-

ously output a waveform at up to 1 MHz.

Users can clock the output operation with

the internal output scan clock or with an

external clock. The internal analog input

clock can pace both the analog input and

output simultaneously.

Digital I/O

The digital I/O lines are configured as

16 inputs and 16 outputs. Users can pace

digital operations with the onboard scan

clock or with an external source.

Digital input scanning

Digital input ports can be read synchro-

nously along with analog channels in a

scan, or asynchronously before, during,

or after an analog input scan. The digital

inputs can sustain rates up to 8 MS/s for

one channel, when no analog channels

are sampled. When analog channels are

also sampled, the rate is 1.33 MS/s for

the USB-1604HS and USB-1604HS-2AO,

and 2 MS/s for the USB-1602HS and USB-

1602HS-2AO.

Digital output scanning

Digital outputs can be updated asynchro-

nously at any time before, during, or after

an acquisition.

Users can generate a digital pattern up

to 4 MS/s. Digital pattern generation

is clocked using the output scan clock.

The USB-1602HS and USB-1604HS Series provides high-speed simultaneous sampling.

Signals connect to BNC (front) and SCSI (rear) connectors. The USB-1604HS-2AO is shown here.

Overview

The USB-1602HS and USB-1604HS Series are high speed devices that can sample

analog, digital, and counter inputs simultaneously, while generating analog out-

puts (when supported) and digital patterns at the same time.

Digital patterns can be generated with

waveforms; both are paced by the same

selected clock. The onboard clock gener-

ates updates ranging from once every

1000 seconds to 1 MHz, independent of

the rate.
