Micropross MP500TCL3 or PT1 / PICC-PCD Simulation ANT
HW: PICOSCOPE 6000 series or General Oscilloscope
SW: PICOSCOPE 6, MPMANAGER3
My MP500TCL3 (or PT1NFC) doesn’t have “Advanced Analog Measurement" software license.Is it possible to perform Load Modulation Amplitude measurement with an external oscilloscope?
The Advanced Analog Measurement software license allows our customer to use MP500 device to perform tests such as LMA measurement, Power transfer measurement, Waveform measurements without
More details about the advanced analog measurement option can be found here:What Advanced Analog Measurement Feature of MP500 Stands For? If an end-user has an MP500 TCL3 (or MP500 PT1NFC) without advanced analog measurement license and would like to measure the Load Modulation Amplitude of a card answer, it is possible to perform a quick informative measurement with an external scope.Note that the method describes below is not compliant with ISO/EMVCo or NFC Forum test specification and is thus informative. Follow the steps below: 1. Build a simple transaction script with MPManager3
Example for Type A
Example for Type B
2. Script settings
Adjust RF Field applied (eg: 50%)
Select RX Channel – Analog IN
Enable/Disable Spy command
CLTO 1 3 0 : TRIG1 port set as Logic”0” when TX OUT
3. Hardware Configuration
External Digital Sampling Oscilloscope
MP500TCL3 (or MP500PT1NFC)
PICC-PCD Simulation antenna
SMA T-Bridge, CONNECTORs
Set Trigger Condition of DSO (CH C)
Trigger Run : Auto or Single
RUN Test Script by MPManager3
Capture the proper area with DSO
Zoom IN for Detail View
Vertical Scale: Adjust (e.g. 200mV) , Time division: 1ms/div
Measure the peak to peak voltage as LMA
This method is informative and is not compliant with ISO/EMVCo/NFC Forum tests methods for which ones - reference antennas have to be used- signal processing algorithms have to be usedA MP500 TCL3 (or MP500 PT1NFC) with advanced analog measurement license and ISO, EMVCO or NFC Forum reference antenna, allows to perform LMA measurement according to ISO, EMVCo or NFC Forum test methods.
