["brand new and high quality\nFeatures:\n4-inch full-view LCD screen, with added for DC dimming, can be seen more clearly when used outdoors. Indoor use is more comfortable.\nThe bridge has been optimized to make full use of the harmonics of Si5351, and the 5th harmonic can now be used to measure up to 1.5GHz.\nWhen the fundamental wave is used, the CH0 output level is increased to 0dBm, and the reflection measurement is more accurate.\nThe previous abnormality of Nanovna-H near 6MHz was resolved.\nReproduce the design of the power management circuit, further reduces power supply noise, reduces USB power supply interference, reduces charging current, and protects the battery.\nOptimized PCB layout, accommodating 1950mAh battery, used for more than 8 hours.\nUART interface is reserved to facilitate DIY expansion.\nLightweight ABS housing provides good for protection for the device.\n\nSpecification:\nMeasurement Frequency: 50KHz~1.5GHz\nRF Output: 0dbm (±2dB, fundamental wave)\nFrequency Accuracy: <2ppm\nFrequency Stability: <0.5ppm\nMeasurement Range: 70dB (50kHz-300 MHz), 60dB (300M-900MHz), 40dB (0.9G-1.5GHz) enable expansion firmware)\n(Note: Please pay attention to the error caused by nonlinear transformation of the fundamental wave when using harmonic measurement.)\nPort SWR: <1.1\nDisplay: 4in TFT (320 x 480)\nUSB Interface: USB type-C Communication Mode: CDC (serial)\nPower Supply: USB 5V 200mA, Built-in 1950mAh battery, Maximum charging current 1A\nNumber of Calibration Points: 101 (fixed)\nNumber of Scanning Points: 101 (fixed)\nDisplay Tracking: 4, Marking: 4, Save Setting: 5\nMeasurement of S-parameters, voltage standing wave ratio, phase, delay, Smith chart, for time domain analysis, et\nMaterials: Metal+ABS\nPackage Size: app.24x14x3cm/9.45x5.51x1.18in\nColor: As pictures shown\nQuantity: 1set\n\nNote:\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage includes:\n1 x NanoVNA Main Unit(Including 4 inch for touch screen, 1950mAh battery)\n2 x 15cm SMA Male to Male RG316 RF Cables\n1 x SMA Female to Female Connector\n1 x SMA Simple Calibration Kit SHORT\n1 x SMA Simple Calibration Kit OPEN\n1 x SMA Simple Calibration Kit LOAD\n1 x USB Type-C Data Cable\n1 x Type-C to Type-C Cable(other accessories demo in the picture is not included.)"]
