Feature: 1. MAIN FUNCTION: This antenna analyzer provides excellent vector network measurement capability, 10KHz‑1.5GHz measurement range, 4in LCD touch screen, ideal for evaluating antenna resonance and SWR. 2. MEMORY CARD PORT: The antenna analyzer has a memory card port to save field test data at any time, supports up to 32GB memory card (not included), can customize date and time. 3. HARMONIC EXPANSION: The old harmonic extension of the si5351 can be used, supporting measurement frequencies up to 1.5GHz, ideal for antenna troubleshooting and performance enhancement. 4. PC CONNECTION AND TX RX: For Touchstone (snp) files of various radios and simulation software can be exported through PC software, TX RX can measure complete S11/S21 parameters (requires manual replacement of transceiver port wiring). 5. MEASURING RANGE: The antenna analyzer has good stability and high accuracy, and supports measurement of S parameters, VSWR, phase, delay, Smith chart and time domain analysis, etc. Specification: Item Type: Vector Network Analyzer ABS Shell: Approx. 75 x 133 x 18mm / 3 x 5.2 x 0.7in (excluding protrusions) Measurement Frequency: 50KHz-1.5GHz RF Output: 0dbm (±2dB, fundamental) Frequency Accuracy:
