Store description excerpt
The dBCalculator software comprises five independent calculation tools: dBm Calculator: This tools helps to add and subtract an arbitrary number of power levels expressed in units of dBm and watt. Voltage Calculator: This tools helps to add and subtract correlated and uncorrelated voltage levels. Unit Converter: This tool calculates for an entry using a unit such as dBm, dBW, mW, W, mV, V, dBV, dBµV and dBu the corresponding values for all other units, for individual impedance values. dB Converter: This tool converts linear power and voltage ratios to dB and vice versa. VSWR Converter: This tool converts reflection quantities such as Voltage Standing Wave Ratio VSWR, reflection coefficient, reflected power, return loss and mismatch loss. PLEASE NOTE: Calculations based on correlated vs uncorrelated levels yield very different results. If you see an unexpected result, please verify the uncorrelated/correlated setting of this app first! The dBCalculator software is based on the application note 1GP77: R&S dBCalculator by Rohde & Schwarz GmbH & Co. KG www.rohde-schwarz.com/appnote/1GP77
