I only able to store the image file in Scope , But i wanted the file to be stored in my PC through LabVIEW using GPIB interface. Please Help me out for this problem.
I only able to store the image file in Scope , But i wanted the file to be stored in my PC through LabVIEW using GPIB interface. Please Help me out for this problem.
I don't know how to do this through LabView, but the SCPI Command to do this is:
:DISK:SAVE:IMAGe "<file_name>" [,<format> [,{SCReen | GRATicule} [,{ON | 1} | {OFF | 0} [,{NORMal | INVert} [,{ON | 1} | {OFF | 0}]]]]].
The Programmers Guide is available here:http://www.keysight.com/upload/cmc_upload/All/Infiniium_prog_guide.pdf
This command is on Page 440.

Hi ,
Thank U for your Reply, But I tried this command , it can only be used to save image on Scope Disk. I need to save the image on my PC.
OK, there are a series of examples in the Programming Guide, in a variety of languages. They all contain a few lines to save the screen contents to a file on the controlling PC.
Here is the 'C' version:
/* Read screen image. */
num_values = do_query_ieeeblock(":DISPlay:DATA? PNG");
/* Write screen image bytes to file. */
fp = fopen ("c:\\scope\\data\\screen.png", "wb");
num_values = fwrite(ieeeblock_data, sizeof(unsigned char), num_values, fp);
fclose (fp);
printf("c:\\scope\\data\\screen.bmp.\n");
Here is the Python version:
# Download the screen image.
# --------------------------------------------------------
sDisplay = do_query_ieee_block(":DISPlay:DATA? PNG")
# Save display data values to file.
f = open("screen_image.png", "wb")
f.write(sDisplay)
f.close()
print "Screen image written to screen_image.png."

Thank You Sir For the Replay This Information was really Helpful.
Can I ask You one more help ,i can fetch the data but the format of the data is new to me. Can you tell me what will be the format of the data and also how to convert it into PNG file. I am using LabVIEW for this.
Both of the examples use PNG format, so I don't understand your question.
The command "DISPlay:DATA? PNG" says 'Send me the display information in PNG format'
Both examples put the received data into an array, then dump the data to a file with a .png extension.

Actually the problem was there were some extra character in front of the data, due to that the image was not coming. So just removed Those characters and got the image.
Thank You for Your Help.
