Welcome to our store! 1. VECTOR NETWORK MEASUREMENT: Vector network analyzer provides perfect vector network measurements in a compact, handheld, standalone, 2.8-inch LCD display, portable, battery-powered or USB-powered package. 2. MEASURING FREQUENCY OF 900MHZ: The 2.8-inch vector network analyzer can support measuring frequencies up to 900 MHz with the odd harmonic extension of si5351. tx Rx methods measure the complete S11 and S21 parameters. 3. METAL SHIELDED: The antenna analyzer is designed with metal shielding to reduce external interference and improve measurement accuracy. Direct output from si5351 in the 50k-300MHz frequency range provides better than 70dB dynamic range. 4. UPGRADED DESIGN: MF HF VHF UHF antenna analyzer provides better than 60dB dynamic range in the extended 300M-600MHz band and better than 50dB dynamic range in the 600M-900M band. The network analyzer can provide you with the best user experience. 5. PC CONTROL SOFTWARE: For NanoVNA vector network analyzer is compatible with original equipment (OE), shaped and functional with simple and practical PC control software, we can export touchstone files (snp) for various radio design and simulation software via PC software. Item Type: Vector Network Analyzer Material: PCB Measuring Frequency: 50KHz-900MHz RF Output: -13dbm (Max -9dbm) Measuring Range: 70dB (50kHz-300MHz), 50dB (300M-600MHz), 40dB, (600M-900MHz) Port SWR: <1.1 Display: 2.8-inch TFT (320x240) USB Interface: USB Type C Communication Mode: CDC (Serial) Built-in Polymer Lithium Battery: 400mAh 1 x Vector Network Analyzer 4 x Connector Accessories 2 x SMA Cable 1 x USB Cable Customers are our top priority.
