2.5 Using Telnet LAN (Port 18)
Telnet provides a means of communicating with the instrument 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
“>” prompts on the command line.
Using the Telnet protocol to send commands to the instrument is similar to communicating with the
instrument over LAN. You establish a connection with the instrument and then send or receive
information using predefined commands. Communication is interactive: one command at a time. The
telnet service is available on port 18.
Once a telnet session to the device is established, the echo can be enabled by typing
SYST:COMM:SOCK:ECHO ON
Following this command a prompt “>>” should become visible.
2.6 USB
There are two standard types of USB ports. The external controller (PC) must be connected via the
USB host port (type A), while the SERIES 7000 and other USB compatible devices must be connected
via the USB interface port (type B)
The SERIES 7000 support the following USB interface protocols:
1) USBTMC class device via VISA: USBTMC stands for USB Test & Measurement Class.
USBTMC is a protocol built on top of USB that allows GPIB-like communication with USB
devices. From the user's point of view, the USB device behaves just like a GPIB device.
USBTMC allows instrument manufacturers to upgrade the physical layer from GPIB to USB
while maintaining software compatibility with existing software, such as instrument drivers and
any application that uses VISA. This is also what the VXI-11 protocol provides for TCP/IP.
2) USBTMC class device with IVI host drivers the application programming interface (API)
provided with the instrument supports general programming using the USB interface under
Windows operating system.
2.7 USB-TMC Interface Connection and Setup using VISA
The USB (Universal Serial Bus) remote control system provides device control via USB, which is
equivalent to control via GPIB. Connection is made through an interface in compliance with USBTMC-
USB488 and USB 2.0.
USBTMC stands for USB Test & Measurement Class. USBTMC is a protocol built on top of USB that
allows GPIB-like communication with USB devices. From the user's point of view, the USB device
behaves just like a GPIB device. For example, you can use VISA Write to send the *IDN? query and
