LXI Class-C Compliant Power Meter
The N1913/1914A EPM Series power meter is a LXI
Class C compliant instrument, developed using LXI
Technology. LXI, an acronym for LAN eXtension for
Instrumentation, is an instrument standard for devices
that use the Ethernet (LAN) as their primary
communication interface.
Hence, it is an easy-to- use instrument especially with the usage of an
integrated Web browser that provides a convenient way to configure the
instrument’s functionality.
