Simulating an inductor

[Coq_Rouge]

Need help pleazzzzzzzz pleazzzzzzzz. I am working as an intern. My boos has told me to simulate an antenna/inductor in a RFID app. But I having some problem. Like why is it only working then I am using a picture called something like "Run Continuously" I am going on a 3 week holiday. And then I came back I hope you Labview experts do have an working application ready for me.

Tanks in advance 🙂  See you in 3 weeks folks

Hahaha Coq you crack me up

But that code wasnt that bad.... you did include error clusters

Clearly the problem is that signal out is not connected to ground.  Thus your inductor has no current return path.  Virtual instruments may require virtual grounds.

Also you do not appear to specify one of the standard RFID frequency bands.

I would have fixed it for you but my eyes still hurt from the glare off the front panel.

You need to coil the antenna anticlockwise, else you get destructive interference. You code currently only works on the southern hemisphere.

Also get rid of the sequence structure, it acts like a faraday cage, severly limiting the signal. Think about it! Each sequence frame costs you at least 20dB. This is well documented elsewhere.

You can get away with not connecting the signal to ground IF you use a wire-nut.

Did you try Ctrl-U?

Ahh!! My EYES!!

Enjoy the time away from your "boos". 

I think I'll start calling my boss my "boos".  I get more boos from him than anyone.

And why are you still using the boring white default color on your block diagram? You can make it fancy looking as well!

While in university, on one practical experiment we had to do, they had configured the stop button not to latch, so before restarting the vi you had to switch it back. I fixed that problem, but they paid by a neon-pink FP. The poor students the year after still sat in front of that!

Thank you all for the help. But it did not help. Then I was on holiday I submitted the solution from altenbach to my boss. I think my and (altenbach) genius scared him and he felt that I was threatening his position. For then I came back I was equipped with a mop and mop frame. Then I asked him if I could get back to the technical department he mumbled something. I did not get it all but I could recognize the words "hell" and "the day freezing to ice" Life is hard as an intern
