3.5.5 BOP VISA INSTRUMENT DRIVER
The VISA instrument driver for the BOP power supply, available for download at www.kepco-
power.com/drivers.htm, simplifies programming with a VISA compatible GPIB controller.
Included are:
• source code (C) for all VISA functions (kp_bophi.c)
• a complete programming reference manual (kp_bophi.doc)
• a sample application of the VISA functions (written in C) which can be used to program
one or more BOP power supplies using a virtual front panel observed on a com-
puter monitor (kp_appl.c)
Although the software drivers supplied by Kepco are VISA compliant, they also require the
installation of the proper VISA driver from your GPIB card supplier. Many vendors supply this
software with the hardware; National Instruments (http://www.natinst.com) has the driver for
their cards available on the internet at a file transfer site (ftp://ftp.natinst.com — find the folder
for support and VISA drivers).
