Experimental Physics and Industrial Control System

Pavel,
I don't know the TDS 5054, but most oscilloscopes come with GPIB, RS232,
or VXI11 (="GPIB over TCP") network interface and are controlled with
text commands. In that case the combination asynDriver/StreamDevice will
do the job.

http://epics.web.psi.ch/software/streamdevice/
If you are lucky, someone has already written a StreamDevice protocol
file for it. But if not, it is not difficult.
Here at PSI, we also run EPICS directly on some oscilloscopes. Many
oscilloscopes nowadays use Windows as the operating system and come with
an API to get direct access to the oscilloscope functions. This allows
to write an EPICS device driver. Running the IOC directly on the
oscilloscope saves some network traffic. With an external IOC, the data
is first transferred from the oscilloscope to the IOC (e.g. via VXI11)
and then from the IOC to the client via Channel Access. With an IOC
integrated into the oscilloscope, you only have Channel Access. But
writing such a driver is somewhat sophisticated.

Hey Andrew!!! Hi Dirk!
It worked :))
This was my first introduction to Epics. Andrew, Dirk, guys! What would
you recommend me to do next? I mean, we have a Tektronix oscilloscope at
work, namely TDS 5054, I guess. And I've read there's a driver written
to hook it up to EPICS. How can I do it? Perhaps, I could try your PLC
driver, Dirk as the next step in mastering Epics. What do you guys think?
Thanks,
Paul

Forget my last message, the quotes are coming from this Makefile rule:
epicsInstallDir.h:
$(ECHO) "FINAL_LOCATION=$(FINAL_LOCATION)"
$(PERL) ../makeInstallDir.pl '$(FINAL_LOCATION)' > $@
On Unix the shell strips out those single quotes, but evidently
yours is not
doing so (my win32-x86-mingw build does strip them, but not my win32-x86
build). You can add two lines to the
base/src/softIoc/makeInstallDir.pl file
to fix this:
=== modified file 'src/softIoc/makeInstallDir.pl'

$path =~ s/\\/\\\\/gx;

print "/* THIS IS A GENERATED FILE. DO NOT EDIT! */\n",
"\n",
I will add this change to the 3.14.12.2 release of Base.
HTH,
