transmission mode in data transmission, as the speed of LAN transmission is high. Generally, the cable between the computer and
vector network analyzer must be no more than 100m long (100Base-T and 10Base-T). For more details of LAN communication, visit
http://www.ieee.org. LAN interfaces are introduced below.
1) IP address
Ensure that the physical connection is smooth for remote control of the vector network analyzer by LAN. Open "Local IP" in the menu
of the vector network analyzer and set the address within the subnet. Example: if the IP address of the master control computer is
192.168.12.0, the IP address of the vector network analyzer should be 192.168.12.XXX, where XXX is 1 to 255.
Only the IP address is required to establish the network connector. The VISA addressing character string is as follows:
TCPIP::host address[::LANdevicename][::INSTR] or TCPIP::host address::port::SOCKET
Where
：
TCPIP refers to the applied network protocol.
host address refers to the IP address of the instrument or the host name, used to identify and control the controlled instrument.
LANdevicename refers to the handle number of the protocol and device (optional).
Select the VXI-11 protocol for No. 0 device.
Select a new high-speed LAN instrument protocol for No. 0 high-speed LAN instrument.
INSTR refers to the instrument source type (optional).
"port" refers to the socket port number.
SOCKET refers to the original network socket resource class.
Example:
If the IP address of the instrument is 192.1.2.3, the effective resource string of VXI-11 protocol is:
TCPIP::192.1.2.3::INSTR
Use the following string for original socket connection:
TCPIP::192.1.2.3::1024::SOCKET
Identification of multiple instrument in remote control system
If multiple instruments are connected in the network, distinguish them with the separate IP address and associated resource string.
The respective VISA resource string is used by the master control computer to identify the instrument.
2) VXI-11 protocol
VXI-11 standard is based on the ONCRPC (Open Network Computing Remote Procedure Call) protocol and suitable for the
network/transmission layer of the TCP/IP protocol. The TCP/IP network protocol and related network services are configured in
advance. The connection-oriented communication complies with the sequential exchange requirements, and connection interruptions
can be identified to prevent the loss of information.
3) Socket communication
The TCP/IP protocol is connected to the network analyzer in the network through the LAN socket. Socket is a basic approach used in
computer network programming, which enables network communication among applications employing different hardware and
operating systems. In this method, the vector network analyzer is connected to the computer through the port for two-way
communication.
