NGE100B
6.1.4 LXI
User Manual 5601.1343.02 ─ 02
Equipped with option R&S NGE-K102, the R&S NGE100B provides an alternative to
remote control the instrument via the web. With the presence of an authenticated
WLAN signal, the instrument automatically connects to a network and navigation can
be made via the web browser according to the WLAN IEEE 802.11 b/g/n standards.

LAN extension for Instrumentation (LXI) is a platform for measuring devices and test
systems based on standard Ethernet technology. LXI is to be the LAN-based succes-
sor to GPIB and combine the advantages of Ethernet with the simple and familiar fea-
tures of the GPIB. This standard provides a new standard for network configuration of
front panel devices via a WEB interface. The central tool for this type of configuration is
a browser.
LXI-compatible devices are divided into three classes, A, B and C, where the function-
ality of the classes is based on each other hierarchically:
●
Class C devices are characterized by a uniform LAN implementation Including an
ICMP ping responder for diagnostic purposes. Devices can be configured with a
WEB browser.
A LAN Configuration Initialize (LCI) mechanism resets the LAN configuration. Class
C LXI devices are also intended to support automatic detection in a LAN via VXI-11
discovery protocol and programming using IVI drivers.
●
Class B adds the IEEE 1588 Precision Time Protocol (PTP) and peer-to-peer com-
munication to base class C. With IEEE 1588, all devices within a network can auto-
matically synchronize to the most accurate available clock, and then provide time-
stamps or synchronization signals for all devices with exceptional accuracy.
●
Class A devices also contain the eight-channel hardware trigger bus (LVDS inter-
face) according to the LXI standard.
Class A and B devices can send and receive software triggers through LAN messages
and communicate with each other without using the controller.
The power supplies of the R&S NGE100B series meet the general requirements of the
LXI Class C and correspond to the version 1.5 (LXI Core 2016). Advanced features are
not supported.
