Feature:
- The circuit design and chip of this version conform to international certification standards and have FCC and CE certification.
- 50KHz-4.4GHz handheld vector network analyzer.
- Small size, easy to carry; work quickly and accurately.
- 1001 Scan Points: Provides more measurement details to avoid missing critical information.
- 7-inch IPS bright LCD screen, capacitive touch control.
- 100dB dynamic range: Well-designed RF front-end circuitry has an optimized noise floor to ensure accurate and reliable measurements.
- The 18650 lithium battery lasts up to 4 hours.
- Powered by USB Type-C interface. A 5V/2A charger is recommended.
- Built-in 8GB memory card for storing calibration status, screenshots and snp files.
- Frequency range 50K-4.4GHz: Covered frequency bands include MF/LF/HF/VHF/UHF; various antennas and filters, amplifiers, attenuators, cables, duplexers, couplers, etc. can be measured.
- 4 buttons + capacitive touch to do everything. The all-metal shell can effectively shield electromagnetic interference.
- Enable one-handed operation mode.
- Ergonomic back support design.
- Excitation power can be adjusted from -42dBm to -12dBm. Suitable for measuring the input impedance of amplifiers.
- N type interface makes the product stable and durable.
- With the TDR function, the device can be used to measure cable lengths and check for cable breaks.
- Variable IF bandwidth: 7 kinds of IF bandwidths are provided, of which the large bandwidth is suitable for fast scanning, and the small bandwidth can significantly reduce the measurement noise.
- Mass Storage: Equipped with 12 save/recall slots for quick save/recall of calibration status. It also supports saving the calibration status as a file. The amount of storage is limited only by the capacity of the memory card.
- Convenient man-machine 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 delays, excitation power, sweep points and averaging factors.
- Virtual U Disk Function: Connect to a computer with a USB Type-C cable to access files in the memory card (cannot take screenshots in this mode). This method can also be used for firmware upgrades.
