VISA is an IO library used to develop IO applications and instrument drivers that comply with industry
standards. It is recommended that the VISA library be used for programming the signal source
analyzer. The NI-VISA and Agilent VISA libraries are similar implementations of VISA and have the
same commands, syntax, and functions.
5.3 Using the USB-TMC Interface with VISA
The USB (Universal Serial Bus) remote control system provides device control via USB, which is
equivalent to control via LAN or GPIB. Connection is made through an interface in compliance with
USBTMC-USB488 and USB 2.0
Type B: USB (USBTMC) interface port
The SERIES 7000 conform to USB Test & Measurement Class (USBTMC) protocol. This simplifies
instrument control considerably because such devices behave just like GPIB devices when
communicating.
You must install the VISA Libraries on your PC in advance. The USB can identify devices
automatically, so once you connect a USB cable to a target device, a dialog box will appear for USB
device registration.
Please see the SERIES 7000 Programmer’s Manual for detailed description of
supported SCPI commands.
5.4 Using the USB-TMC Interface with IVI drivers
Please see the SERIES 7000 Programmer’s Manual for detailed description of
supported SCPI commands.
5.5 Using the GPIB Interface
This section describes how to set the interface necessary to use the GPIB (General Purpose Interface
Bus) of the SERIES 7000.
The GPIB interface operates with IEEE488.2 and SCPI. The instrument can be controlled by a GPIB
external controller. When controlling the SERIES 7000 using GPIB commands from the external
