Enhance your radio frequency measurements with this advanced SWR Meter, designed for precision and convenience. Featuring a large 1.29-inch Organic Light Emitting Diode (OLED) screen, this meter offers five versatile display modes, including normal and peak hold modes, to provide clear and detailed readings of forward power, standing wave ratio, antenna end power, and efficiency. Engineered for accuracy, it utilizes a fitting algorithm combined with a high-speed average detection mode to achieve measurement accuracy better than ±5%, ensuring reliable and precise results across a frequency range of 1.6 to 50MHz. Key Features: · Large 1.29-inch OLED Display: Provides sharp, easy-to-read measurements with multiple display modes for enhanced usability. · High Accuracy Measurement: Incorporates advanced detection technology for accuracy better than ±5%, suitable for professional and hobbyist applications. · Standing Wave Alarm Function: Features an intermittent beep alarm when the standing wave ratio (SWR) reaches or exceeds 2.0, and a continuous beep alarm at SWR ≥ 3.0, allowing for quick identification of antenna issues. The alarm function can be turned off as needed. · Wide Frequency and Power Range: Supports frequency measurements from 1.6MHz to 50MHz and power measurement from 0.5W to 200W, making it compatible with a broad range of RF equipment. · Low Insertion Loss and Standing Wave Insertion: Ensures minimal signal interference with insertion loss less than 0.12dB and standing wave insertion ≤1.02 at 1.6-30MHz and ≤1.05 at 30-50MHz. · Rechargeable and Long-lasting Battery: Equipped with a built-in 3.7V 900mAh rechargeable lithium battery, offering up to 90 hours of continuous operation. Recharge conveniently via USB Type-C. · Compact and Portable Design: Lightweight and small in size (approx. 88 x 38 x 64mm), this meter is easy to carry and ideal for fieldwork or on-the-go use. · USB Type-C Interface and Firmware Upgrade Support: Allows for efficient data communication and future firmware updates to maintain optimal performance. · Impedance: Standard 50 Ω for compatibility with most RF systems.
