Buying Guide
One of the most essential functions is testing amplifiers consequently you’ll need an oscilloscope that has great resolution; This will allow you to identify all weak, dying, or unusable power output stages are all these elements with much clarity.
What should I look for when buying an oscilloscope for audio?
Bandwidth:
The bandwidth of an oscilloscope is the maximum frequency it can display. It indicates with what accuracy the input signal can be measured. Frequency range is also a major consideration when purchasing an oscilloscope.
Sample Rate:
The sample rate indicates how many samples per second the oscilloscope can take. The higher the sample rate, the better in theory.
However, you’ll be hard-pressed to find a 100MHz scope with a sample rate above 2 GS/s for under $1000 at least, and even then it might not have enough memory depth to handle it, so you may be better off sticking to something around 30-50 MHz.
Memory Depth:
This indicates how many samples can be stored. The larger this is, the more complex and multi-faceted the scope can be. The sample rate and memory depth of your scope will have a direct link to how much time you’ll spend programming it, so make sure you get what you need and nothing less.
Waveform Update Rate:
This indicates the speed with which a scope can update the display of its waveform; many oscilloscopes are not fast enough to keep up with an audio signal and may struggle to display the waveform correctly or in real-time, which could result in inaccuracy.
This is the frequency at which the scope draws an updated picture of the waveform on a screen or computer. The faster the better since these updates are very helpful in troubleshooting.
Size and cost:
Measurements taken in an oscilloscope need to be carefully monitored by a technician. This is because there should not be any disturbances when taking a measurement. If have low budget See our article on Best Oscilloscope Under 500 Reviews (Top 5 Picks in 2023)
Therefore, it should be noted that larger and higher-quality equipment serves to provide more accurate measurements and is quite expensive as well.
The number of channels:
The higher the number of channels, the more work can be done simultaneously by increasing the speed of measurement and analysis. This means that measurements are less time-consuming and efficient which may speed up the overall process. This can be a factor when deciding on which brand or model to buy.
