9. Tips pamaké
- For optimal performance and to avoid signal noise, always use a high-quality, stable 5V power adapter, preferably one that is 3C certified.
- When working with higher frequencies, especially sine waves above 300KHz, remember to engage the
FILTERfunction for a cleaner output, keeping in mind a slight amplitude reduction may occur. - The device automatically saves your last settings, making it convenient for repeated experiments or measurements.
- The square wave output is particularly useful for calibrating oscilloscope attenuators and probes due to its sharp transitions.
