Specific driver ivi read and write to binary file for tektronic oscilloscope 7000 series

[Dennis_Knutson]

You are STILL using the hardcopy to file. Please follow the directions correctly. Even better would be to test all commands in MAX first.

The Communication with oscilloscope throung NI MAX with the same codes succeed to get the screenshot binary data. So i suspect there got bugs for the 7000 series IVI specific driver.

Where can i report to? Is there any other ways can obtain the screenshot to laptop besides using the SCPI commands?

Did you change your code to use the GPIB port instead of File?

Dear crossrulz,

I got change the SCPI from "FILESystem:READFile <filepath>" to "FILESystem:PRInt <filepath>, GPIb".

However, their result still the same---blank.

That's still not the correct change. Did you really look at what crossrulz posted with the hardcopy command.

The image you posted is obviously not blank.

Yeah, that isn't right at all.  Here are the commands I used.

HARDC:PORT GPIB;
HARDC:INKS ON;
HARDC:FORM PNG;
HARDC START

 From there is is a simple VISA Read until you get all of the data.

Thank you for reply.

However, the same commands cannot be applied. 

First, there are no commands as below in 7000 series:

HARDC:PORT GPIB;-----> only have HARDCopy:PORT {FILE|PRINTER}
HARDC:INKS ON;-------> only have EXPort:PALEtte {COLOr|INKSaver|BLACKANDWhite}
HARDC:FORM PNG;------> only have EXPort:FORMat {BMP|JPEG|PCX|PNG|TIFF}
HARDC START

You can refer to the programmer manual attached below.

Is there any alternative way?

Thank you.

Best regards,
