Title: Yokogawa DL1540 Communication Interface User’s Manual
Post by: davorin on December 20, 2017, 04:18:11 pm

Evnin' (o;

Has anyone stumbled upon the Yokogawa DL1540 communication interface users manual?
Especially I am interested of course in the GPIB commands (o;

Nothing on the net to be found..just the plain user manual...but not the comm manual with number IM701510-11E.


thanks in advance

A communication manual for the DL1540C/1540CL is available from here:
http://labit501.upct.es/~fburrull/docencia/FundamentosTelematica/OsciloscopioDL1520/IM701530-11E_010%20Communication%20Interface%20Manual.pdf (http://labit501.upct.es/~fburrull/docencia/FundamentosTelematica/OsciloscopioDL1520/IM701530-11E_010%20Communication%20Interface%20Manual.pdf)

The GPIB commands may be sufficiently similar to those in the DL1540 communications manual to be of some use.

Seems to be identical..thanks (o;

Just wonder why all scopes I know don't have a GPIB command to put it back into local mode (o;

A quick test gets me a TIFF capture:

Code: [Select]

<?php
 $string = "";

 $u = ibfind("1540");
 ibwrt($u, "IMAG:FORMAT TIFF");
 ibwrt($u, "IMAG:SEND?");
 
 $r = ibrd($u, $string, 100000);
 $string = substr($string, 8, -1);
 
 file_put_contents("/var/www/html/image.tif", $string);;
?>

And with this little addition:

Code: [Select]

<?php
 $image = "";

 $u = ibfind("1540");
 ibwrt($u, "IMAG:FORMAT TIFF");
 ibwrt($u, "IMAG:SEND?");
 
 $r = ibrd($u, $image, 100000);
 $image = substr($image, 8, -1);

 $imagick = new Imagick();
 $imagick->readImageBlob($image);
        $imagick->setImageDepth(24);
 $imagick->setImageFormat("png");
 $clut = new Imagick();
 $clut->newPseudoImage(2, 1, "gradient:orange-black");
 $imagick->clutImage($clut);
 header("Content-Type: image/png");
 echo $imagick;
?>

It is shown in a browser like:

should be identical in commands..
C is for color display and L is for longer memory..
to switch to local mode maybe use ":COMM:REMOTE OFF", not sure.

Well..it is actually simple...as "go to local mode" has nothing to do with a command, but with the GPIB bus itself...

In PHP that would be then a simple:

Code: [Select]

ibloc($u);
