RF vs RST Scope

This tool works as an equation solver : you can choose the parameter (variable) to be computed, and fix the other parameters. It also supports multiple systems of units : American (US) and metric (SI). 1) Quarter Wave Antenna : you can compute the length of a quarter wave antenna or solve other parameters (frequency or wave length). 2) Path Loss in Free Space : you can compute the path loss in free space or solve other parameters (frequency, wave length, or distance). 3) VSWR & S11 : you can compute the voltage standing wave ratio or solve other parameters (modulus of reflection coefficient (linear or logarithmic), argument of reflection coefficient, real part of input impedance, imaginary part of input impedance). 4) Power Converter : you can convert the power between [dBm] or [W] units, and compute the tension [dBuV] (into 50 [ohms]). 5) Reflected & Delivered Power : you can compute the ratio of the delivered power to input power or solve other parameters (ratio of reflected power to input power, modulus of reflection coefficient, voltage standing wave ratio). 6) Microstrip Transmission Line : you can compute the characteristic impedance of a microstrip transmission line, or solve other parameters (relative permittivity, track’s thickness, distance from the track to the ground plane, or track’s width). 7) Stripline Transmission Line : you can compute the characteristic impedance of a stripline transmission line, or solve other parameters (relative permittivity, track’s thickness, distance from the track to one reference plane, or track’s width). Some remarks : -The microstrip solver is based on the IPC-D-317A design guidelines. -The stripline solver is based on the IPC-D-317A design guidelines.

This is an app for amateur radio operators with a narrow band of audio frequency, spectrum scope & waterfall display. You can get a rich display by microphone inputting the speaker output of a radio that does not have a spectrum scope or waterfall function. The FFT allows you to distinguish between the dot and dash of Morse code. [function] 1. Ability to change the speed of the waterfall 2. Ability to adjust the level of audio input 3. Function to switch the display band between wide and narrow 4. Display pause function (pause / cancel by touching the screen) 5. Function to switch the cross hatch ON / OFF by longTap 6. Frequency resolution is fixed at 40Hz. 7. Function to switch the USB/LSB by Left/Right Swipe 8.Recording/Playback function of Input Sound RST Scope(Free) https://www.youtube.com/watch?v=1s9RvOFp52g
