Feature:1. Broad Ranges: The improved frequency algorithm can support measurement frequencies up to 1.5GHz using the odd harmonic extension of the si5351. si5351 direct output provides better than 70dB of dynamics in the 50K-300MHz frequency range, better than 60dB of dynamics in the extended 300M-900MHz band, and better than 40dB of dynamics in the 900M-1.5GHz band.2. Easy Testing: The default firmware master function is used for antenna performance measurements. TX RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually change the transceiver port wiring.3. Smart Design: With memory card port and battery circuit management function, measurement data or screenshots can now be saved in it at any time. You can connect your cell phone using the data cable and see clear high definition images on your phone.4. Stable Power: Can be powered by battery or USB. Built in 1950mAh battery for 2 hours of continuous operation, or connect to a mobile power source or power supply if additional operating time is required.5. Simple Carrying: Designed to have a light weight and a compact size as well, the convenient carrying and storage make the outdoor working much easier.Specification:Item Type: Vector Network AnalyzerMeasurement Frequency: 50KHz-1.5GHzRF Output: 0dbm (2dbm)Measurement Range: 70dB (50kHz-300MHz), 60dB (300M-900MHz), 40dB (0.9G-1.5 GHz).
