EPICS: Tektronix TDS Oscilloscope GPIB Support
This page is the home of the EPICS GPIB device support for Tektronix
TDS oscilloscopes. The software provided here is an enhancement to
the TDS 540 oscilloscope software developed by Ben Franksen at BESSY
and for the most part, is unchanged.
This site gives access to the software source code, information on other
modules which are needed to install and run it, and documentation on
how to include and use it in your EPICS applications. Please email any
comments and bug reports to
who is responsible for coordinating development and releases.
The software can drive the following types of hardware:
Where to Find it
You can download the software by anonymous ftp from the links in

Installation and Building
After obtaining a copy of the distribution, it must be installed and built
for use at your site. These steps only need to be performed once for the
site (unless versions of the module running under different releases of
EPICS and/or the other required modules are needed).
Start with an existing EPICS application area and cd to the src directory.
Unpacking the distribution tar file produces a <tdsGpib> directory.
Add tdsGpib to your src/Makefile and run gnumake. Check for any
Example TDS 380 GDCT databases reside in tdsGpib/Db.
Example TDS 380 DM2K displays reside in tdsGpib/dl.
An example TDS 380 bumpless reboot config file resides in tdsGpib/savedata.
Example subroutines for parsing a waveform preamble, writing a waveform to
a file, and resetting a LAN box are provided in tdsGpib/src/subTDS.c and
are used by subroutine records in the tdsGpib/Db databases.
When using tdsGpib in your application, you must also include
the common gpib device support plus one or more GPIB drivers provided by
Ben Franksen at BESSY
EPICS GPIB Module Software). You will also need the scaled
waveform record provided by Ben Franksen or some equivalent record.
If you build one library in your application, you'll want to include
tdsLib, gpibLib, and swfRecord.o along with the normal base support.
You'll want to include devTDS300Gpib.dbd and/or
devTDS540Gpib.dbd, gpib.dbd, and swfRecord.dbd along with the normal
base dbd files when building your application's database definition file
(see tdsGpib/src/TDSInclude.dbd for an example).

This software was originally developed by Ben Franksen (BESSY) for TDS 540
and was upgraded to work for both TDS 380 and 540 by Stephanie Allison (SLAC).
It is used at the following EPICS sites:
