Features- The circuit design and chip of this version comply with international certification standards, and it has FCC and CE certification- 50KHz-4.4GHz handheld vector network analyzer- Compact size makes it portable; fast to work in an accurate way- 1001 scan points: present more measurement details and avoid missing key information- 7" IPS highlight LCD screen, capacitive touch to control- 100dB dynamic range: The well-designed RF front-end circuit has an optimized noise floor to ensure accurate and reliable measurements- Built-in 18650 lithium battery's endurance time reach 4 hours- Powered through USB type-c interface. 5V/2A charger is recommended- Built-in 8GB memory card to store calibration status, screenshots and snp files- Frequency range 50K-4.4GHz: Covered frequency bands include MF/LF/HF/VHF/UHF; can measure all kinds of antennas and filters, amplifiers, attenuators, cables, duplexers, couplers, etc.- 4 buttons + capacitive touch to complete all operation. All-metal casing can effectively shield electromagnetic interference- One-hand operation mode is enabled- Ergonomically designed with back support- The excitation power is adjustable from -42dBm to -12dBm. Suitable for measuring the input impedance of amplifiers- N-type interface makes the product stable and durable- With TDR function, this device can be used to measure cable lengths and check cable breaks- Variable IF bandwidth: 7 kinds of IF bandwidth are available, of which large bandwidth is suitable for fast scanning, and small bandwidth can significantly reduce measurement noise- Large-capacity storage: Equipped with 12 save/recall slots, which can quickly save/recall the calibration state. It also supports to save the calibration status as a file. The amount of storage is limited only by the capacity of memory card- Convenient human interface- Support logarithmic amplitude, phase-frequency diagram, group delay, Smith, polar coordinate, linear amplitude, VSWR, real part/imaginary part, resistance/reactance, quality factor and other display formats- Quickly set start and stop frequencies, electrical delay, excitation power, sweep points and average coefficients- Virtual U disk function: use a USB Type-C data cable to connect to your computer to access the files in the memory card (cannot take screenshots in this mode). This method can also be used for firmware upgrade- Powerful host computer- Product size: 190 x 130 x 30mm/7.5 x 5.1 x 1.2" (without size of RF interface)Specification- Frequency range: 50kHz~4.4GHz- RF output power: -42dBm to -12dBm (1dB step)- RF interface form: N-type female connector (with N to SMA adapter)- RF input power: 0dBm Max (DC
