Using Telnet Lan - Keysight E4428C ESG RF Programming Manual

Using IO Interfaces
Using LAN
Before you can use sockets LAN, you must select the signal generator's sockets port number to use:
• Standard mode. Available on port 5025. Use this port for simple programming.
• TELNET mode. The telnet SCPI service is available on port 5023.
NOTE
For backward compatibility, on the E8663B, ESG, and PSG, the signal generator also accepts
references to the Telnet SCPI service at port 7777 and sockets SCPI service at port 7778.
Ports 7777 and 7778 are disabled on the Keysight MXG.
For the MXG, beginning with firmware versions A.01.51 and greater, the default telnet port
is 5024. Telnet port 5023 is still available for backwards compatibility. Refer to the SCPI
Command Reference.
An example using sockets LAN is given in "LAN Programming Interface Examples" on page 117 of this
programming guide.

Using Telnet LAN

Telnet provides a means of communicating with the signal generator over the LAN. The Telnet client,
run on a LAN connected computer, will create a login session on the signal generator. A connection,
established between computer and signal generator, generates a user interface display screen with
SCPI> prompts on the command line.
Using the Telnet protocol to send commands to the signal generator is similar to communicating with
the signal generator over GPIB. You establish a connection with the signal generator and then send
or receive information using SCPI commands. Communication is interactive: one command at a time.
NOTE
The Windows 2000 operating systems use a command prompt style interface for the Telnet
client. Refer to the Figure 2-7 on page 47 for an example of this interface.
Windows XP operating systems and newer can use this section to better understand how to
use the signal generator with port settings. For more information, refer to the help software
of the IO libraries being used.
The following telnet LAN connections are discussed:
• "Using Telnet and MS–DOS Command Prompt" on page 44
• "Using Telnet On a PC With a Host/Port Setting Menu GUI" on page 45
• "Using Telnet On Windows 2000" on page 46
• "The Standard UNIX Telnet Command" on page 47
A Telnet example is provided in "Unix Telnet Example" on page 48.
Using Telnet and MS–DOS Command Prompt
