Introduction
64-bit Digital I/O offers high-performance digital I/O wherever your application needs it

The Keysight Technologies, Inc. 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 application needs it.

The Keysight 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 configurable 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, standard software drivers and more. The LXI standard is supported by multiple vendors, enabling lower cost of test with accelerated test integration and development.
