EPICS: Stanford Research Systems Lock-In Amplifier GPIB Support
This page is the home of the EPICS GPIB device support for Stanford Research
Systems (SRS) lock-in amplifiers. The software provided here is for the
SR830 DSP Lock-In Amplifier.
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 <srsLiaGpib> directory.
Add srsLiaGpib to your src/Makefile and run gnumake. Check for any
The SR830 example database and template reside in
The SR830 example DM display
resides in srsLiaGpib/dl.
Example bumpless reboot config files resides in srsLiaGpib/savedata.
When using srsLiaGpib 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).
If you build one library in your application, you'll want to include
srsLiaLib and gpibLib along with the normal base support.
You'll want to include devSrsLia830Gpib.dbd and/or
devSrsLia530Gpib.dbd and gpib.dbd along with the normal
base dbd files when building your application's database definition file
(see srsDsGpib/src/srsDsInclude.dbd for an example).
