Connectivity and LXI-

Class C Compliance

Conventionally, the E4418/4419B remote interfaces consist of GPIB and

RS232/422. The GPIB interface is mostly used for automated testing in

manufacturing rather than the RS232/422 interface; it is used less frequently with

slow performance.

The N1913/1914A introduces additional USB and LAN connectivity ports on top of

the existing GPIB interface. The USB and LAN interface are growing in popularity

as PC interfaces and their use is in line with the direction of other Agilent

instruments (see Figure 10). The USB 2.0 host interface provides PC connectivity

via USB cable.

The LAN interface can be conﬁgured by users and provides enhanced LXI-Class

C compliance. The unrivalled connectivity of USB and LAN enables users to cope

with the majority of PC control applications, and allows the test system to be easily

integrated into the modern test environment.

The N1913/1914A is a LXI-Class C compliance instrument that combines the

advantages of Ethernet with simplicity and familiarity of GPIB. Having a web

browser over the LAN connection allows the users to view and control the

N1913/1914A remotely (see Figure 11 and 12). The web browser contains key

information such as the manufacturer, model number, serial number, description,

hostname, MAC address, and IP address.
