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: <2ppm Frequency Stability: <0.5ppm Measuring Range: 70dB(50kHz-300MHz) 60dB (300M-900MHz), 40dB (0.9G-1.5GHz) with extended firmware enabled (When using harmonic measurement, pay attention to the error caused by the nonlinear transformation of the fundamental wave) Port SWR: < 1.1 Display: 3.95in TFT (320 x 480) USB Interface: USB Type C Communication Mode: CDC (Serial) Charging Voltage: DC 5V 1A Power Supply: Built in 2000mAh 18650 lithium ion battery Number of Calibration Points: 101 (fixed) Number of Scan Points: 101 (fixed) Display Tracks: 4, Markers: 4, Settings Save: 5 Uses: Measure S parameters, VSWR, phase, delay, Smith chart, time domain analysis, etc. Features: 1. 4in full view LCD screen, with DC dimming added, you can see more clearly when used outdoors, and more comfortable when used indoors 2. Bridge is optimized to make full use of the harmonics of Si5351, and now it can measure up to 1.5GHz with the 5th harmonic 3. When using the fundamental wave, the CH0 output level is increased to 0dBm, and the reflection measurement is more accurate 4. Solve the abnormality of the previous analyzer near 6MHz 5. Reproduce the designed power management circuit to further reduce power supply noise, reduce USB power supply interference, reduce charging current, and protect the battery 6. Optimized PCB layout to accommodate 2000mAh battery, use for more than 8 hours; (with built in battery) 7. Reserve UART interface for easy DIY expansion 8. A new ABS shell is made by opening the mold, which is light and convenient to protect the machine 9. Beautifully packaged to provide security for subsequent transportation..
