(1) ATQA response for TX_IRQ as trigger
Fig 44. AWG setup for type A @ 106
The amplitude defines the peak voltage level of the LMA: the LMA output toggles
between 0V and the defined amplitude. The AWG output can directly drive a Reference
PICC modulation input.
Note: EMVCo LMA levels normally are in the range of 700 … 800 mV for minimum LMA
test in operating Volume 1. For compliance test it is recommended to use a calibrated
reference tool like e.g. the CTC Advanced WavePlayer.
The PICC response itself can be defined as hexadecimal data. The Fig 44 shows the
example of a MIFARE DESFire like ATQA, which does not contain a CRC, but SOF,
EOF and parity.
