Rohde&Schwarz ESL (How can i get the value)

[vov0vov]

Hi. Good morning guys..

I want to get the value of the bargraph displayed on the R&S ESL monitor in real time. 

There's no problem setting the product and looking at the value in ESL, but I can't bring the value. Help me.

I will attach the VI I used, so please guide me to solve it.

Thank you so much.
