64-bit Digital I/O offers high-

performance digital I/O wherever your

application needs it

The Agilent L4450A is a high-speed

64-bit digital I/O instrument that is LXI

Class C compliant. With its small size

and Ethernet connectivity, the Digital

I/O can be placed wherever your appli-

cation needs it.

The Agilent L4450A has 64 bi-

directional lines configured as eight

8-bit channels. Each 8-bit channel has

programmable polarity and thresholds

up to 5 V. The 128 k of memory is

useful for simulating and capturing

digital patterns up to 10 MHz. The con-

figurable handshaking protocols can be

used for a wide variety of applications.

In addition, the two 10 MHz counter

channels can be used to count events,

frequency, period, duty cycle, pulse

width and totalize.

Using this LXI instrument, you’ll get all

the benefits of an Ethernet connection,

built-in instrument web interface, stan-

dard software drivers and more. The

LXI standard is supported by multiple

vendors, enabling lower cost of test

with accelerated test integration and

development.
