Export marker of VNA using Labview

[Vcl]

Hi

How to use export marker in Labview. I didn't find any vi blocks for this.

I am using ZNC VNA and Labview 2016. I have installed all the drivers of ZNC VNA

I assume you have the manual for this Instrument.  It appears to use the IEEE 488.2 GPIB Protocol to communicate with the Instrument, allowing you to program with text commands and retrieve data as text (see Chapter 7, Programming Examples in the R&S ZNC Vector Network Analyzer manual).

In LabVIEW, you can find the GPIB sub-Palette as part of the Instrument I/O Palette.

R&S supply a LabVIEW driver for their ZNC VNAs - https://www.rohde-schwarz.com/ca/driver/znc/

Therein you will find a VI to read marker values, browse under the CALC VIs. 

And if I remember correctly there's an example using markers too.  (Examples are separate download!)

Bob's advice is also sound, you can easily do it yourself with a SCPI command.  Manual is here - https://cdn.rohde-schwarz.com/pws/dl_downloads/dl_common_library/dl_manuals/gb_1/z/znc_1/ZNC_ZND_Use...

Look at page 549 of the manual for a list of all possible SCPI commands related to Markers.  The basic command to read the amplitude of the Y-value of a marker is like "CALC<channel#>:MARK<N>:Y?"
