5 This is an example of an NFC ISO/IEC 15693 vicinity reader / tag capture
9 Hardware setup for the capture
10 ------------------------------
12 * HydraBus v1.2 + HydraNFC Shield v1.1
13 * Using firmware HydraFW (HydraBus) v0.9-beta-92-g3c34dfd 2019-10-12
14 Tag ISO/IEC 15693 Vicinity ICODE SLI/SLIX (uID RW)
15 * CH1 connected to HydraBus/HydraNFC PA5
16 * Capture HydraNFC reader clock 13.56MHz
17 * CH2 connected to “Calibration Coil ISO 10373-6”
18 * Capture NFC signal between NFC Reader & NFC Vicinity Tag
19 * Impedance Adapter 50 Ohm (also called Rigol Impedance Adjuster 50 Ohm)
20 used on CH2 with "Calibration Coil ISO 10373-6"
21 * PL-50 (50 Ohms +/-1%, 2 WATT, DC - 1GHz)
22 * PicoScope 3406DMSO (8bits @ 1 GS/s, Memory 512MS)
23 * Picoscope v6.x software on Windows 7 SP1 64bits
25 NFC ISO/IEC 15693 Vicinity read UID capture was demodulated with an Octave
26 script which creates CH3 & CH4 and all channels are displayed with PulseView.
32 CH1: connected to HydraBus/HydraNFC PA5 (capture HydraNFC reader Clock 13.56MHz)
33 CH2: connected to "Calibration Coil ISO 10373-6" (capture NFC signal between Reader & Tag)
34 CH3: clock reconstructed from CH1 / CH2 to decode CH4
35 CH4: filtered data envelope reconstructed from from CH1 / CH2
