![]() The Digital Meter displays either immediate or peak values of the signal strength. The Analog Meter displays either immediate or peak value of signal strength in selected units. The Options include Stay On Top and Set Integration Time which makes it possible to adjust the time interval for peak level measurements. The Save Log and Save Log As functions are used to store log files on the disk. ![]() The File menu contains the Open Calibration Table function, using which it is possible to select user-defined calibration tables. ![]() The S-meter panel can be divided into three parts: The top-bar menu, the analog and digital meter, and the various controls. This can be accomplished using a separate program called S-meter Plug-in Calibrator. Improved accuracy can be achieved by editing the calibration cables for each individual receiver. These tables will typically provide signal level measurement accuracy within 5dB. Tables with average calibration values for WiNRADiO receivers are included with this plug-in. These tables contain conversion constants using which the raw values arriving from a receiver's internal A/D converter are translated into dBm units (from where they are recalculated in microvolts or S-units as required). The S-meter relies on calibration values stored in user-editable tables stored in separate files. The S-meter can display either immediate values (in any of the three selectable units) or peak values, determined over user-definable time periods. A logging function is also included, where the measured values are stored in a file with user-definable intervals. This facility is useful wherever it is necessary to measure absolute signal strength levels. For microvolts, either RMS value or peak-to-peak values can be displayed. The signal level can be displayed in microvolts, dBm or S-units. This plug-in makes it possible to add a powerful analog and digital Signal Strength Meter to any WiNRADiO 1000/1500/3000 and G3 series receiver. ![]()
