KVE-60C SWR HF Vector Antenna Impedance Graphical Analyzer Amateur Ham Radio DIY

KVE-60C SWR HF Vector Antenna Impedance Graphical Analyzer Amateur Ham Radio DIY

Brief introduction:
- 0.5-60 MHz Color Graphic VNA Analyzer
- Pocket-Size, Incredible Performance! Truly accurate SWR, R, X and Z!
- This pocket-sized wonder breaks the mold for analyzer design with user-friendly  convenience, top notch accuracy, and a vivid TFT multi-color display. Don`t let  the size fool you, it is packed with all the VNAfeatures and performance you  need!
- For example, get data for SWR, resistance (R), reactance (X), and impedance  magnitude (Z) delivered on a color-coded high-resolution bar-graph display or  sharply defined swept-frequency plots.
- Get continuous DDS frequency coverage with 100-Hz resolution and a full  selection of tuning steps and sweeps.
- There's a movable marker that calls up alpha-numeric data for any point on any  plot -- and a memory to collect current data when you turn the analyzer off.
- Get other useful features too, like a built in help menu and a field-strength  indicator warns when powerful interference is present.
- Best of all, juggling batteries is a thing of the past -- a long-running  lithium-polymer power source is built right in. Recharge via any USB port.
