Subject: [Scopes] BMP image record??
Hello again,
As I mentioned earlier we are running a series of experiments with
our high current switches. I have written simple support ("...with a
little help from my friend" Dirk Zimoch) for the Tektronix TPS2000
over RS232 using StreamDevice and ASYN, so now I can remotely arm
the scopes, set its properties, save waveforms on to the CF card,
etc. But...
In order to not run back and forth and see if everything went OK
(which is rather tiresome and time consuming), we need a
confirmation from the scopes. I don't want to deal with the
implementation of the waveform records for now, all I have got so
far is that I save them on the flash card.
As such a confirmation I see transferring the BMP (or PNG) image
from the scope (sort of Print screen) on to the operator PC somehow.
There is a special SCPI command "Hardcopy start". Which mimics the
Print button on the scope's front panel. I have tried to transfer a
BMP file via Hyperterminal (and Python script) and it worked out
well (more or less).
How could this be ported to the EPICS database from the IOC and
client standpoint, so an operator could see the oscillogram on the
screen and decide whether the experiment went well, so she will save
the waveforms and move on to the next experiment?
The image file is maximum ~ 46Kb (20Kb on average).
Any thoughts?
