Overview
RWC5010A NFC Tester A test equipment to test NFC Forum Devices
specified in NFC Forum Technical Specifications.
Provides very convenient working environment with full control over all system parameters.
Supports various kinds of functions such as power vs. time measurement, link analyzer and modulation characteristic measurement.
FDT and GT are measured in real time with Link analyzer.
Provides sensitivity test with variable VDC and load modulation amplitude

Pre-calibration
VDC
In LISTEN Test, the VDC can be set directly with the
pre-calibrated data according to the reference
Poller/Listener combinations, not by tuning TX level
to reach its target value.
Load Modulation
In POLL Test, the load modulation amplitude can be
set directly with the pre-calibrated data according to
the reference Listener, not by tuning TX level to reach
its target value.
