Of course, the real smart card does not allow to vary the load modulation level, which
helps to find the optimum (sensitivity). So, an extended test setup as shown in Fig 42 can
be used to control the LMA voltage level. This setup contains
•
Reference PICC (ISO, EMVCo or NFC)
•
Keysight Arbitrary wave generator (AWG [13])
•
NFC Cockpit with PNEV7462B
Fig 42. Enhanced Rx Matrix Test setup with AWG
The input parameters for the test matrix run are defined in an XML file (see 6.10.3.1).
The test can be started in the NFC Cockpit (<Start RxMatrix>). The test result is stored
as table, when the test is finished. The table can be opened with e.g. Microsoft Excel for
interpretation (<View Output>).
6.10.3 Rx Matrix XML input file
The Rx Matrix Test requires the input configuration in an XML file. A few example XML
files (for type A, B, F, 15693 and I-Code ILT) are part of the NFC Cockpit package:
c:\nxp\NxpNfcCockpit_v<VERSION>\cfg\RxMatrix\RxMatrix_PN7462AU\
Refer also to 11 for one example for type A without AWG and one example for type B
with AWG.
Such an XML file defines all test parameters. The user can create (copy & paste) own
XML files, chose any from the existing XML files and then start the test.
