Has anybody used the driver of network analyser (ZVB) offered by Rohde&Schwarz company?

I have got some problems of understanding....

Hi,
how can I help you? I developed the driver and I'm also using it. Did you see examples on R&S webpage?

[yokojs]

yeah, right, I have seen it and downloaded the driver.

I want to use this driver to realize s-parameters controlling, marker controlling, recalling the old set-up and so on.

I have read the application example already, but i still don't know for example how i can control the marker.

Have u got some idea of it or do u have some simple example for this one?

Thank you very much!

In general the driver follows the menu structure of the instrument itself. So if you know where you can find certain property/feature in the instrument's menu, you will easily find it in the driver. All marker related VIs are in Trace->Marker palette. Search functions are implemented in palette Trace->Marker->Search. R&S Instrument Drivers are equipped with CHM help file which includes also a tree-structured navigation contents which might help you find the VI you're looking for. CHM can be opened from drivers's VI Context Help window by clicking the link 'Click here for more help'.

Thank you for your information!
Acctually I have already found out all the models in the driver.
My problem is ununderstanding of some part of the block diagram of  the RSZVB Measurement Example, that is to say, I get some barriers to understand the flowing diagram of this model.
What I mean is that, for example, I want to remotely control the marker of network analyser, perhaps I can just add the one of the marker models given by driver trees into the block diagram of the RSZVB Measurement Example offered by the driver. But where I can put it in?

Thanks!

There're few types of marker in ZVB instrument - for detailed description of each of them please consult operating manual and/or help system of instrument and driver. The simplest regular marker first has to be switched on using RSZVB Set Marker State.vi, then it you can either directly set stimulus value of interest (use RSZVB Set Marker Stimulus) or let the instrument search for peaks (use RSZVB Marker Search.vi). At the end you can read out the Y value of the marker using RSZVB Get Marker Response.vi. The value is returned as complex number (for detailed description see help). Put this sequence into example just after querying the response from instrument (RSZVB Trace Response Data.vi). I can't test it right now, if it will not work for you, please let me know.

Thanks a lot!
I will try it as soon as possible!

[yokojs]

excuse me, could you give me your e-mail address? I want to paste some pics here but failed to show you the block diagram.
thanks!
