Feature: 1. 7IN LCD DISPLAY: The network analyzer uses a 7in IPS high brightness LCD screen, capacitive touch, 100dB dynamic range, and the RF front end circuit has an optimized noise floor to ensure accurate and reliable measurements. 2. WIDE RANGE: Built in 8GB memory card to store calibration status, screenshots and SNP files, frequency range from 50K‑4.4GHz, covering frequency bands including MF, LF, HF, VHF, UHF, can measure antennas and filters, etc. 3. METAL SHELL: The vector network analyzer adopts an all metal shell structure, which can effectively shielding electromagnetic interference, back support, ergonomic design, and easy and fast operation. 4. MULTIPLE FUNCTION: The excitation power is adjustable from -42dBm to -12dBm, suitable for measuring the input impedance of the amplifier, with TDR function, the analyzer can be used to measure cable length and check for cable breaks. 5. 7 IF BANDWIDTH: large bandwidth is suitable for fast scanning, small bandwidth can significantly reduce measurement noise, and is equipped with 12 save recall slots, which can quickly save and recall calibration status. 6. DISPLAY FORMATS: Support logarithmic amplitude, group delay, polar coordinate, linear amplitude, VSWR, quality factor and other display formats, set start and stop frequency, electrical delay, excitation power, sweep point and average coefficient.
