Sample Rate

Sample rate is the speed at which the oscilloscope takes measurements of the signal. A higher sample rate means more data points are captured, giving you a more accurate representation of the signal. The general rule is to have a sample rate at least 3-5 times higher than the bandwidth of the signal you’re measuring. For instance, if you're measuring a 10 MHz signal, you'll want a sample rate of at least 30-50 MS/s. A good sample rate is crucial for the performance of your computer connected oscilloscope.

Number of Channels

How many signals do you need to measure simultaneously? Most scopes have two or four channels, which is usually enough for most projects. If you're working with complex circuits, you might want more channels. Consider the number of signals you need to monitor when choosing a computer connected oscilloscope.

Vertical Resolution

Vertical resolution refers to the precision with which the oscilloscope can measure voltage. It’s typically measured in bits. Higher vertical resolution gives you better accuracy and the ability to see subtle signal variations. 8 bits is standard, but you might want to consider 12 or 16 bits for more demanding applications. This is important when choosing your computer connected oscilloscope.

Triggering Options

Triggering options are crucial for capturing the specific signals you're interested in. Look for scopes with a variety of triggering modes, such as edge triggering, pulse width triggering, and more advanced options like serial bus triggering.
