Feature:1. 4.3in Touch Screen: The handheld vector network analyzer uses 4.3in IPS TFT LCD screen, which has a larger viewing angle and can be seen clearly under strong outdoor light, can measure S parameters, voltage standing wave ratio SWR, phase diagram, group delay, Smith circle Figure etc.2. Large Capacity Battery: Upgraded large capacity 5000mAh lithium battery, longer standby time, extended USB interface, can use as a mobile power source to charge for Android or for IOS mobile phones when not in use. The IC uses 2A high current charging, and the charging time is shorter.3. Measuring Range: The measuring range of NanoVNA-F is 50k-3GHz. You can go to the official website to update the spread spectrum to 10Khz-1.5Ghz. Use the harmonic spread spectrum of the output signal of the clock chip SI5351 to measure the frequency to 1000MHz.4. Small and Powerful: Upgrade user program through virtual U disk. Switch to a power switch with a stronger sense of operation and a better sense of operation, support for switching between Chinese and English menus.5. Upgraded Aluminum Shell: This vector network analyzer uses a standard aluminum shell to protect the SMA head, reducing the interference of external electromagnetic waves to the instrument.Specification:Item Type: V2 Vector Network AnalyzerMaterial: Aluminum AlloyMeasuring Frequency: 50KHz -3GHzDisplay: 4.3in, Resolution 800 x 480Battery: 5000mAh Lithium Ion Battery (Shipped with built in battery)RF Output Power: -9dBm (Error Within 1GHz: 1dB)Frequency Accuracy: <0.5ppmS21 Dynamic Range: 70dB (1.5GHz), 60dB (3GHz)S11 Dynamic Range: 50dB (1.5GHz), 40dB (3GHz)2 Port Return Loss: 20dB typ (1.5GHz), 13dB min (3GHz)Calibration Points: 101 PointsScanning Points: 101 PointsNumber of Tracks: 4Number of Marker Points: 4 (The marker point bar can be moved up and down on the screen)Setting and Saving: 5 groups (After saving, can be directly recalled for the later use without recalibration, the parameters saved before the last shutdown will be automatically recalled the later time the device is turned on)Support calibration result interpolation, after adjusting the measurement frequency band, can be measured without recalibrationScan Time: About 1.9s/1 Time (50kHz~3000MHz Full Frequency Band).Package List:1 x Vector Network Analyzer2 x RF Cable 1 x Type C Data Cable6 x Adapter1 x Touch Screen PenNote:By default, USB is used for charging.
