70 Keysight Signal Generators Programming Guide
Using IO Interfaces
Using USB (Keysight MXG)
Selecting I/O Libraries for USB
CAUTION The Keysight MXG’s USB interface requires Keysight IO Libraries Suite 14.1 or newer to
run properly. For more information on connecting instruments to the USB, refer to the
Keysight Connection Expert in the Keysight IO Libraries Help.
The I/O libraries can be downloaded from the National Instrument website, http://www.ni.com, or
Keysight’s website, http://www.keysight.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 Keysight 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 Keysight SICL can be used to develop applications for the USB interface. See
Keysight’s website for information on SICL.
CAUTION Because of the potential for portability problems, running Keysight SICL without the
VISA overlay is not recommended by Keysight Technologies.
Setting Up the USB Interface
Rear Panel Interface (Mini–B 5 pin)
To use USB, connect the USB cable (Refer to Table 2-3, “USB Interface Cable,” on page 71, for USB
cable information.) between the computer and the signal generator’s rear panel Mini–B 5–pin USB
connector.
