Using IO Interfaces
Using USB (Agilent MXG)
Selecting I/O Libraries for USB
CAUTION The Agilent MXG’s USB interface requires Agilent IO Libraries Suite 14.1 or newer to
run properly. For more information on connecting instruments to the USB, refer to the
Agilent Connection Expert in the Agilent IO Libraries Help.
The I/O libraries can be downloaded from the National Instrument website, http://www.ni.com, or
Agilent’s website, http://www.agilent.com. The following is a discussion on these libraries.
NOTE I/O applications such as IVI-COM or VXIplug&play can be used in place of VISA.
VISA VISA is an I/O library used to develop I/O applications and instrument drivers
that comply with industry standards. It is recommended that the VISA library be
used for programming the signal generator. The NI-VISA and Agilent VISA
libraries are similar implementations of VISA and have the same commands,
syntax, and functions. The differences are in the lower level I/O libraries used to
communicate over the USB; NI-488.2 and SICL respectively.
NI-488.2 NI-488.2 I/O libraries can be used to develop applications for the USB interface.
See National Instrument’s website for information on NI-488.2.
SICL Agilent SICL can be used to develop applications for the USB interface. See
Agilent’s website for information on SICL.
CAUTION Because of the potential for portability problems, running Agilent SICL without the
VISA overlay is not recommended by Agilent Technologies.
