7月12日 的 Electrician RF Power Toolkit 應用程式分析

Electrician RF Power Toolkit delivers a rugged, practical suite of calculators designed for the daily realities of electrical engineering, radio frequency work, and electronics repair. No fluff, no internet dependency, and no hunting through unrelated consumer tools. Just clean, fast, and precise calculations paired with a built-in notepad to log field measurements before moving to the next task. This gives electricians, service techs, RF hobbyists, electronics builders, and bench technicians a practical set of calculators for everyday electrical and radio work. It is made for the jobs where you need a number now: checking a circuit, sizing a resistor, comparing power levels, working through a coax problem, checking VSWR, estimating reactance, or saving a field note before you move on. Use it for: - Ohm's law calculations - Voltage, current, resistance, and power checks - Watts, amps, and voltage relationships - Resistor power and voltage drop - dB, dBm, watts, and volts RMS conversion - Return loss, VSWR, mismatch loss, and reflection coefficient - Coax cable impedance, capacitance, and inductance - Capacitor and inductor reactance - RLC impedance estimates - Frequency, wavelength, and cable delay - Skin depth by material and frequency - Pi and T attenuator design - Transformer turns ratio checks - Parallel resistance and tolerance ranges - Binary and hexadecimal conversion - Percentage, ppm, mean, median, and standard deviation - Geometry and unit conversions - Saved records for notes, measurements, job sites, cable runs, and components Popular calculator tools include: - Ohm's Law Solver - Power in Circuit - dB Converter - Return Loss / VSWR - Reactance Calculator - Impedance Calculator - Coax Cable Calculator - Attenuator Designer - Skin Depth - Frequency / Wavelength / Delay Electrical and power tools: - Solve voltage from current and resistance - Solve current from voltage and resistance - Solve resistance from voltage and current - Calculate watts from volts and amps - Calculate current from watts and voltage - Calculate voltage from watts and current - Estimate resistor power using V squared over R - Estimate resistor power using I squared R - Check high dissipation situations before choosing parts RF and signal tools: - Convert dBm to volts RMS - Convert volts RMS to dBm - Convert watts to dBm - Work with 50 ohm and 75 ohm systems - Calculate return loss from impedance - Calculate VSWR from reflection coefficient - Estimate mismatch loss - Compare voltage ratio and power ratio in dB - Work through antenna, feedline, and station checks Coax and transmission line tools: - Estimate coax characteristic impedance - Use inner diameter, outer diameter, and dielectric constant - Estimate capacitance per meter - Estimate inductance per meter - Convert frequency to wavelength - Convert wavelength to frequency - Estimate cable delay from length and velocity factor - Estimate stub filter frequency Component and bench tools: - Capacitive reactance - Inductive reactance - RC series impedance - RC parallel impedance - RLC magnitude and phase - Parallel resistor total - Tolerance minimum and maximum - Transformer voltage ratio - Transformer impedance ratio - Air core coil estimate with Wheeler formula Records are included for real job follow-up: - Add tags for fast searching - Flag important records - Duplicate records for repeat jobs - Share saved record summaries - Import and export records as JSON backups Monthly Pro is a 1-month auto-renewable subscription.
