T8200PRO: LF/HF Resonance Frequency Tester

Key Features

  • Able to test both LF and HF bands(test items: resonance frequency, attenuation, quality factor, optional: reading ID)
  • Able to test the transmission or the reflection characteristics (a directional coupled is incorporated)
  • Test results, waveforms are written to a log file automatically

※ We have the standard and the DIO (equipped with digital IOs) types. The DIO type can be controlled by a PLC.
The test probe is optional.

Test Principle

With the test probe magnetically coupled with the device under test(smart IC card, RFID tag), the frequency response (transmission or reflection) is measured.


● Resonance frequency test for contactless IC cards and RFID tags
● Resonance frequency test for RFID reader/writer antennas
● Testing the self-resonance frequency of coils used for wireless power supply equipments
● Testing the self-resonance frequency of passive devices: power inductors, ultrasonic sensors

Test Principle Contactless resonance frequency measurement with magnetic coupling
Measuring Mode Transmission / reflection characteristics
