IEEE-488 (GPIB) Interface Solutions
• PCI and USB bus versions
• IEEE-488.2 compatible for fast
data transfer
• Windows

 7/Vista/XP/2000
drivers included
• LabVIEW

 and LabWindows/CVI
support
• Compatible with any standard
GPIB instrument
Keithley’s GPIB interface solutions make it easy 
to add standard IEEE-488.2 bus control to any 
PC system. These high speed tools can control 
as many as 14 GPIB instruments or other devices 
over a distance of up to 20 meters. They are 
ideal for use with automated test equipment in 
laboratory and industrial applications.
The Keithley Model KPCI-488LPA is a low-
profile, GPIB interface plug-in card that is 
32-bit/33MHz PCI bus compatible. Its PCI 
interface supports both 3.3V and 5V PCI envi-
ronments, making it suitable for most desktop 
computers and industrial PCs, including the 
new low-profile desktop systems. This low-cost 
solution supports Windows 7/Vista/XP/2000, and 
its driver library is command compatible with 
National Instruments
™
 and Capital Equipment 
Corporation
™
 command functions.
The Keithley Model KUSB-488B USB-to-GPIB 
interface turns any computer with a USB port 
into a fully functional GPIB controller. The 
KUSB-488B’s small form factor makes it per-
fect for use with laptop computers in portable 
applications or for other applications in which 
the computer has no available PCI plug-in board 
slots. The product is USB 2.0 compliant and 
has an IEEE data transfer rate upwards of 1.5 
MB/s through the USB port. No external power 
is required. KUSB-488B has a built-in 2-meter 
USB cable.
Software
The included utility software simplifies the setup 
and use of Keithley GPIB interface solutions and 
saves programming time. Every solution ships 
with 32-bit dynamic link libraries for Application 
Development Environments (ADEs) running 
under Windows 7/Vista/XP/2000 and drivers for 
the most current programming languages. This 
adds up to full compatibility with a full array of 
software,   including:
• Microsoft Visual Studio 6.0 (Visual Basic,
Visual C++)
• Microsoft Visual Studio .NET (Visual
Basic .NET, C#)
• Microsoft Visual Studio 2005 and up
• Borland Delphi, Borland C Builder 6.0
• LabVIEW Version 7.0 and up (VISA and
IEEE-488.2)
• LabWindows™/CVI Version 7.0 and up (VISA
and IEEE-488.2)
Hardware Compatibility
These GPIB Interface solutions are fully compat-
ible with all of Keithley’s GPIB capable instru-
ments. The Model 7010 adapter is required 
for the Model 428-PROG when used with 
the KUSB-488B.
