Marker move to specific position

E4440A Spectrum Analyzer.

Hi everyone! 

When the measure mode Occupied Channel Bandwidth is turn on, there will have two diamond 🔷, at the 99% mark at lower and upper bound automatically as shown in photo attached

It there any method, I can move the marker to the position of  the Diamond value 🔷?

(for manual method, I need to manually spin the knot until the marker overlap with diamond, in order to be able to take the data value) 

I am unable to find any command or things liddat in the manual, Plz help. 

if It is impossible to do it , Do let me know as well! 😁

I don't see anything in your post related to LabVIEW and I am wondering why you post this here in the LabVIEW forum. Is there LabVIEW code behind all this and can you modify it?

Maybe decide on a better place and ask a moderator to move your post.

It would be appropriate to reach out to Keysight support to know what you want is actually possible on E4440A.

Maybe there are folks in the NI Discussion forum who knows the answer or maybe not, but definitely, Keysight support must be able to answer your question.

This is the Labview program which it will do all the required setting on the instrument , measure and capture the screenshot into the PC automatically via a GPIB - USB cable. 

For this OBW, I would like to make Marker1 to move to the lowerbound (Diamond Marker) which generate by the instrument under OBW mode, after that then i do a screencapture with the marker value on screen(in the screenshot).

Thus, i am asking if it is possible to move the marker to the Diamond marker automatically. 

Instead of me turning the dial to move the marker to the Diamond marker, before I can screencapture the screen.

hi,

my bad for not writing my post with enough details.

it is about LabView.

i had replied myself with a further explanation about my question

Guess that depends on your definition of "automatically". You could write code to read the "diamond"  locations and move your markers to that location... of course, all the required commands would be in the instrument manual. Have you looked in the programmer manual yet?

[santo_13]

In order to automate any instrument, you need two things

1. Know the instrument command (automation) to perform the action (typically SCPI commands for bench instruments)
2. Know how to implement the command in the programming language of your choice (like LabVIEW, C, C++, Python etc.,)

Question - do you think LabVIEW is the only missing piece in the equation, do you know what command to execute to move the marker?

If you know the command and are just not sure how to implement it best in LabVIEW, we will be able to help you sort it out. On the other hand, if you don't know the command to send to the instrument, I would recommend reaching out to the instrument manufacturer to find out the command (or search the manual).
