รายละเอียดของสินค้า Chunnuan KVE520A Vector Color Graphic Impedance Antenna Analyzer Meter for VHF/UHF HAM VU - intl KVE520A Vector Color Graphic Impedance Antenna analyzer for VHF/UHF Amateur HAM Radio Features and Functions: The KVE520A breaks the size barrier for RF-analyzers by delivering user-friendly convenience, top-notch accuracy, and a vivid TFT multi-color display in an ultra-compact package. Although small in size, the KVE520A is loaded with a great selection of Single- Frequency and Swept-Frequency VNA functions. Use the Single-Frequency mode to view Standing Wave Ratio (SWR), Resistance (R), Reactance (X), and Local Interference levels (S) simultaneously on a high-resolution analog bar-graph display. High-accuracy numerical values for SWR, R, X, and Impedance Magnitude (Z) appear on the same display. This mode also allows you to use your analyzer as a precision signal generator. Use the Scan-Frequency Mode to graphically plot SWR, R, X, and Z. All four plots are captured as a sequence of sharply defined color graphs. Simply toggle through each screen for a complete visual analysis. There's also a tunable marker on each screen you can use to call up precise numerical values for SWR, R, X, and Z at any point along the plot. The KVE520A has internal memory, so there's no need to worry about lost data -- if you turn your unit off, the last measurement will still be there when you turn it on again. The KVE520A is continuously tunable from 133-177 195-280 395-520 MHz with 100-Hz resolution and a wide range of tuning steps and scan widths for shaping your plots. The advanced DDS stimulus generator delivers rock-solid stability, smooth skip-free tuning, and a powerful +5 dBm test signal that overrides most strong local interference. There's also a built-in Field-Strength Indicator to warn when high interference levels are present. Best of all, you can forget about swapping out dead batteries, working around NiCd cell memory, or hunting for lost wall chargers because the KVE520A's long-running lithium-polymer power source is built right in. Simply connect to any available USB port on your computer or USB wall charger to recharge. A built-in smart-charger with LED status monitoring let's you know when the analyzer is ready to go. Once you're up and running, you'll quickly discover the KVE520A has many user-friendly features including soft-menu labeling for the command keys and a built-in 8-page Help Menu. Don't forget to personalize the KVE Antenna Analyzer Boot Screen by entering your call letters or name. You can use your android phone micro usb cable to charge this tester Specifications: 1 Display: Sharp transflective TFT, 1600 million colors, QVGA resolution.
