Features: 1.Touch Screen and Battery: Vector net analyzer fits original equipment, form and function. Includes a 2.8in touch screen and 400mAh battery for 2 hours of offline use. 2.Frequency Algorithm: Vector net analyzer improved frequency algorithm, odd harmonic extension support up to 900MHz measurement frequency, with metal shielding sheet, can reduce external interference to improve measurement accuracy. 3.Simple and Practical: With PC control software, the vector net analyzer provides excellent vector net measurement functions, easy to use, connected and available to use, card size. 4.Frequency Band and Dynamic: Vector net analyzer direct output of 50K to 300MHz band provides better than 70dB dynamic, extended 300M to 600MHz band can provide better than 50dB dynamic, 600M to 900M band better than 40dB dynamic. 5.Reduced Number of Connection Points: The UHF antenna analyzer is designed to meet the requirements through the use of an OE engine management system. The number of connection points is reduced to allow faster response to changes. 6.PCB and Silicone: The antenna analyzer uses a printed circuit board protected by silicone for excellent resistance to temperature changes and vehicle vibration. specification:Item Type: Vector Net Analyzer Material: PCB, Silicone Display: 2.8 Inch TFT (320x240) Measurement Range: 50KHz-300MHz RF Output: -13dbm ( Maximum -9dbm ) Port SWR:
