| Display shows unusual values for signal strength or audio modulation. | Attempting to set values outside the valid range. | Remember that signal strength -70 to -132dBm and audio modulation 800Hz are the only valid values. Other values displayed are invalid. |
9. Колдонуучунун кеңештери
- Signal Waveform: The provided information does not specify if the generator produces sine wave or square wave signals. It is typically an RF carrier with AM modulation. For specific waveform details, further testing or manufacturer clarification may be needed.
- Signal Strength Conversion: The signal strength is provided in dBm. If you need to convert this to microvolts (µV), you will need to know the impedance of your system (typically 50 Ohms for RF). The formula for converting dBm to voltage (V) into a 50 Ohm load is V = sqrt(10^((dBm - 10)/10) * 0.05).
- Button Colors: Note that the colors of the buttons may vary and are sent randomly. This does not affect functionality.
