Using IO Interfaces
Using USB
Selecting I/O Libraries for USB
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.
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.
Setting Up the USB Interface
Rear Panel Interface (Mini–B 5 pin)
To use USB, connect the USB cable (Refer to Table 2-1, “USB
Interface Cable,” on page 60 , for USB cable information.) between the
computer and the signal generator’s rear panel Mini–B 5–pin USB connector.
The Keysight X-Series 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.
I/O applications such as IVI–COM or VXI
plug&play
can be used in place of
VISA.
Because of the potential for portability problems, running Keysight SICL
without the VISA overlay is not recommended by Keysight Technologies.
