Buying Guide for the Best Oscilloscope Multimeters

When choosing an oscilloscope-multimeter, it's important to understand that this device combines the functionalities of both an oscilloscope and a multimeter. This means it can measure electrical signals and display them graphically, as well as measure voltage, current, and resistance. To pick the best fit for you, consider the key specifications and how they align with your specific needs and applications.
BandwidthBandwidth is the range of frequencies that the oscilloscope can accurately measure. This is important because it determines the highest frequency signal that the oscilloscope can capture. If you are working with high-frequency signals, you will need a higher bandwidth. For general electronics work, a bandwidth of 50-100 MHz might be sufficient. For more advanced applications, such as RF or high-speed digital circuits, you might need 200 MHz or more. Choose a bandwidth that is at least five times higher than the highest frequency you expect to measure.
Sample RateThe sample rate is how many times per second the oscilloscope samples the signal. This is crucial because a higher sample rate provides a more accurate representation of the signal. For basic applications, a sample rate of 1-2 Giga samples per second (GS/s) is usually adequate. For more detailed analysis, especially with high-frequency signals, you might need 5 GS/s or higher. Ensure the sample rate is at least ten times the highest frequency you need to measure.
ChannelsChannels refer to the number of separate signals the oscilloscope can measure simultaneously. This is important if you need to compare multiple signals. For simple tasks, a two-channel oscilloscope might be enough. For more complex tasks, such as analyzing multiple points in a circuit, a four-channel oscilloscope would be more suitable. Consider how many signals you need to measure at once to determine the number of channels you need.
DisplayThe display is where you view the signals and measurements. A larger, higher-resolution display makes it easier to see details and analyze signals. For basic use, a smaller display might be sufficient, but for more detailed work, a larger display with higher resolution is beneficial. Consider how much detail you need to see and how comfortable you are with smaller versus larger screens.
Input ImpedanceInput impedance is the resistance the oscilloscope presents to the circuit being measured. This is important because a high input impedance minimizes the impact on the circuit. Most oscilloscopes have an input impedance of 1 MΩ, which is suitable for most applications. Ensure the input impedance matches your requirements to avoid loading the circuit and affecting the measurements.
Multimeter FunctionsSince this device also functions as a multimeter, consider the range and accuracy of its voltage, current, and resistance measurements. This is important for general troubleshooting and testing. For basic use, standard ranges and accuracies are sufficient. For more precise work, look for higher accuracy and wider ranges. Determine the typical measurements you will be making to choose the appropriate multimeter specifications.
ConnectivityConnectivity options, such as USB, Ethernet, or Wi-Fi, allow you to connect the oscilloscope to a computer or network for data transfer and remote control. This is important for data logging, analysis, and sharing results. For basic use, USB connectivity might be enough. For more advanced applications, such as remote monitoring or integration into automated test systems, Ethernet or Wi-Fi might be necessary. Consider how you plan to use the oscilloscope and choose the connectivity options that best support your workflow.
