Major Test Challenges Today:

Cost – Instruments, rack, cables, software, training, tran sitions

Performance – Measurement accuracy/resolution/bandwidth, system th roughput

Compatibility – Application software, PC standard I/O, existing ins truments

Flexibility – Built-in measurements, personalities, test topologi es, triggering

Longevity – Measurement performance, PC standard I/O, support li fe

Ease of use – Front panel operation, drivers, manuals, program mo nitoring

Size – Sized for performance, reduce rack space, faceless modules (military)

What is LXI?

LAN Extensions for Instruments


Marlo Manaloto

What is LXI?

Applying proven standards to test & measurement

Physical standards (IEC sizes, Power, Cooling, Front panel Indicators, Reset button)

Instrument web pages(Information, Set-up, control, and data access from a web browser)

Interface standards (IVI driver, VXI-11 discovery, Device locking, Security)

Ethernet standards(TCP/IP, DHCP, URL / IP addresses, Dynamic DNS, Auto-MDIX)

Trigger standards (optional) (LAN triggers, IEEE 1588 time synchronization, Trigger bus)
