Using SCPI Interfaces

Using the E7501A SCPI Interface

Understanding the

E7501A

SCPI Interface

The E7501A SCPI interface, through its own GUI, takes input from a

program or programming environment. It provides a connectivity interface

to the Agilent E7501A arbitrary analog signal development system.

The E7501A SCPI interface GUI can be used with four connection types:

• Telnet

• Sockets

• RS-232

• VXI-11

Telnet, Sockets, and RS-232 come with all Microsoft Windows’ operating

systems. VXI-11 requires an Internal Instrument interface to be configured

with the I/O Config utility before it can be enabled; the I/O Config utility is

available only with Agilent I/O Libraries.

If you are using a National Instrument MXI-VXI Slot 0 module, a VXI-11

connection can not be enabled; it requires an Internal Instrument interface to

be configured, and this functionality is not available with

National Instruments MXI-VXI Slot 0 modules.

Telnet, Sockets, and VXI-11 each use different communication protocol

(communication rules), listen on different ports, and communicate over a

LAN [Local Area Network]; one or more sessions of communication can be

configured and used simultaneously.

RS-232 is a serial COM port interface that uses a direct cable (a null-modem

cable) between the computer running the Agilent E7501A arbitrary analog

signal development system and the computer running the user’s

programming environment.
