JDSU J745A spectrum analyser / VNA repair & mini review

<< < (7/7)

Hi
I'm working with jd785A device and i'm trying to communicate with my device by SCPI commands. i read your txt file but:
my command is: SPEC:TRAC:MAX
unfortunately the command which set my trace mode to maxhold and minhold did not work. even i tried every single possible form of spelling maxhold and minhold (like MAXH, MAXHOLD, ...) .

nctnico:
It is possible the JD785A has a different SCPI command set. I found manuals for other JDSU / Viavi units which have different SCPI commands. So it looks like the SCPI commands are not standarised across the product line.

Thank you for your guidance
Is it possible that they have removed access to this mode for this device? Or maybe this problem can be solved by updating the device?

I won't hurt to update the software if that isn't the latest version already.
