Selection Tips

The LK-7202-OA is a dedicated OTA radiated testing shielding box (pneumatic version, 0.6–6 GHz, ≥70 dB shielding effectiveness), which is different from LK-6400/LK-6401/LK-6402 series board-level conducted testing shielding boxes. LK-64XX Series: Focuses on PCB/module conducted RF testing, including RF signal routing, parameter calibration, and functional verification. LK-7202-OA: Focuses on antenna radiated performance testing, including OTA TRP/TIS measurement, radiation pattern evaluation, and wireless terminal RF performance verification.
