How to use cockpit to get LMA by general card as type a or b w/ PN5180?

[Frankfu1]

Hi,

From AN11740 at page 50, I can see signals of LMA and AUX1. 

In my side, we already understood how to get AUX1 by cockpit. 

How to set the procedure for getting LMA by ISO1443-A or B?

My procedure it to set Reader\Load Protocol\Endless REQA\RF field on and use the pickup coil to get card information. Seems I ONLY can see RF field w/o tx waveform and LMA.

Plz guide us to get LMA.

Thanks,

Frankfu

Is it possible to sniffer LMA waveform w/ "general type A card" and pickup coil by cockpit and oscilloscope instead of AN12549?

As the video of ch3, https://www.nxp.com/video/nfc-antenna-design-4-optimization-debugging:ANTENNA-DEBUGGING-VIDEO

Or only ReferencePICC w/ AWG can see LMA waveform?

Thanks,

Hello,

This should also be possible. However, the accuracy should not be as good as AWG and reference PICC.

Have a nice day.

Hello,

I confirmed the question in the related team and recommend the customer uses the system of AN12549

Hello,

Please refer to the Figure 6. Minimum test setup for LMA tests of the PN5190 antenna design guide as the link.

It is similar with PN5180.
