Programming the SERIES 7000
The SERIES 7000 can be accessed through LAN or USB interface. All interfaces use standard SCPI
command set to pass commands to the device. GPIB interface is also available optionally.
2.1 LAN
The SERIES 7000 can be remotely programmed via a 10/100/1000Base-T LAN interface and LAN-
connected computer using one of several LAN interface protocols. The LAN allows instruments to be
connected together and controlled by a LAN- based computer. LAN and its associated interface
operations are defined in the IEEE 802.2 standard.
The SERIES 7000 support the following LAN interface protocols:
1) Socket based LAN: the application programming interface (API) provided with the instrument
supports general programming using the LAN interface under Windows operating system.
2) VXI-11
3) Telephone Network (TELNET): TELNET is used for interactive, one command at a time
instrument control.
4) Internet protocol optionally supported
For LAN operation, the instrument must be connected to the LAN, and an IP address must be
assigned to the instrument either manually or by using DHCP client service. Your system administrator
can tell you which method to use. (Most current LAN networks use DHCP.)
DHCP Configuration
If the DHCP server uses dynamic DNS to link the hostname with the assigned IP address, the
hostname may be used in place of the IP address. Otherwise, the hostname is not usable.

2.2 Ethernet Interface Connection and Setup
The SERIES 7000 fully supports the IEEE-802.3 standard. Most front panel functions (except power
on/off) can be remotely controlled via a network server and an Ethernet connection. The SERIES 7000
software supports the TCP/IP network protocol.
Ethernet uses a bus or star topologies where all of the interfacing devices are connected to a central
cable called the bus, or are connected to a hub. Ethernet uses the CSMA/CD access method to
handle simultaneous transmissions over the bus. CSMA/CD stands for Carrier Sense Multiple
Access/Collision Detection. This standard enables network devices to detect simultaneous data
channel usage, called a collision, and provides for a contention protocol. When a network device
detects a collision, the CSMA/CD standard dictates that the data will be retransmitted after waiting a
random amount of time. If a second collision is detected, the data is again retransmitted after waiting
twice as long. This is known as exponential back off.
