High Precision Vector Network Analyzer with 4in LCD Display - Shortwave Antenna Analyzer for Accurate RF Parameter Measurement | USB Interface & Noise Reduction Technology | Ideal for Ham Radio, Antenna Tuning & Electronics Testing

Feature:1. LCD DISPLAY: The vector analyzer adopts a 4in full‑view LCD screen, which adds DC dimming, making it more comfortable for indoor use and clearer for outdoor use.2. HARMONICS USE: The electric bridge is optimized to take full advantage of the harmonics of the Si5351, which can be measured to 1.5GHz with the 5th harmonic.3. HIGH ACCURACY: When using the fundamental wave, the CH0 output level is increased to 0dBm, and the reflection measurement is more accurate.4. NOISE REDUCTION: Good power management circuit further reduces power supply noise, reduces USB power supply interference, reduces charging current, and protects battery.5. REASONABLE LAYOUT: Optimized PCB layout, 2000mAh battery can be used for more than 8 hours, and UART interface is reserved for DIY expansion.Specification:Item Type: Vector AnalyzerABS Shell Size: Approx. 75 x 133 x 18mm / 3 x 5.2 x 0.7in (excluding protrusions)Measurement Frequency: 50KHz-1.5GHzRF Output: 0dbm (±2dB, fundamental)Frequency Accuracy: <2ppmFrequency Stability: <0.5ppmMeasurement 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 of the fundamental wave)Port SWR: < 1.1Display: 3.95in TFT (320 x 480)USB Interface: USB Type-CCommunication Mode: CDC (Serial)Power Supply: USB 5V 200mA, built in 2000mAh battery, maximum charging current 1ANumber of Calibration Points: 101 (fixed)Number of Scan Points: 101 (fixed)Display Tracks: 4, Markers: 4, Settings Save: 5Functions: Measure S parameters, VSWR, phase, delay, Smith chart, time domain analysis, etc.Packag
