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.
