Query regarding data from Network Analyzer RSZVB to computer

[NurHidayah]

Hi. Sorry for disturbance. 

I would like to ask u about the data. I have download RSZVB Measurement Example in LABVIEW from Rohde&Schwarz website. Then, the data from did not appear in the graph. The connection that i have use is LAN cable. 

Or the result come up if using GPIB cable?

Did not have any idea. 

Need your help.

Thank you very much.

I note that it seems that your VISA Resource Name control is empty. Have you configured the instrument in MAX and assigned it a VISA alias to select in that control?

Thank you for replying.

Yes, i already configured the instrument in Measurement and Automation. In labview measurement, i have pressed the VISA resource name. 

Then, i have changed the start and stop frequency. After the simulation running, no waveform in graph.

I do not know what the problem is. 

Need your help. 

Thank you very much.

Run NI Spy / NI IO trace, save the log and post it. We'll see what is going on there.

Thank you for replying.

I have followed the instruction. Please refer the attachment of Capture1.spy.

Need your help.

Thank you very much.

From what I see in a log your trace data was transferred correctly and there was nothing wrong. You should also have file C:\Trace.csv on your host computer (open with Excel or text editor) with the frequencies and trace point values.

Unfortunately your screenshot doesn't show the X axis of the graph, so I cannot judge if data X coordinates are OK.

Run attached VI, I changed plot points style and Y axis range so it should be visible.

Thank for helping me.

I have done simulations that you give, but the output graph is still not there.

can u refer the attachment. 

Need you help again. 

Thank you very much.

This is data that i have when doing the measurement. The data is OK, but the waveform is not there. 

I do not know what the problem is.

Need your help. 

Thank you very much.

Hmm, your graph ranges are messed up, I cannot see why. Let's try if graph data are OK. Run attached example - it saves c:\graph_data.txt file on your host PC. Post it and we'll see the actual numbers going into that XY graph

Thank for helping.

I have done the instructions. Can you refer the attachment. I have measured S11 parameter. 

Need your help.

Thank you very much.
