This Product Selection Guide contains information to help select products in the Oscilloscopes category on DigiKey.com
Oscilloscopes are measurement tools that create a visual representation of electronic signals. An essential tool for those who work with electronics, they are used to observe and measure high-speed phenomena, with more advanced examples capable of measuring signals with frequency content approaching the GHz range. As a general rule they exchange absolute accuracy and measurement resolution for speed, with even modest multimeters likely to yield better measurements than most oscilloscopes of the DC/low-frequency phenomena for which multimeters are well-adapted.
SelectionCharacteristics
Type: Indicates the style and configuration of the device.
Bandwidth: Indicates the maximum frequency or the range of frequencies the device is designed to measure.
Channels: Indicates the number of signals that a device can measure simultaneously.
Display Type: Describes the user interface for indication.
Interface: The way the device is equipped to communicate the data it is measuring.
Memory Size: The size of data storage for data being measured.
Function: Indicates what the device is able to do with measurement data. Also indicates if the device has additional features.
Probe Type: Indicates type, attenuation factor(s), and quantity of probes included with a device.
Sampling Rate (Per Second): The number of measurements per second the device is able to take.
Input Impedance: Describes a device’s input impedance in terms of resistance and parallel capacitance.
Rise Time (Typ): Characterizes a device’s square wave response; the shortest-duration rising edge signal that a device can measure accurately, subject to manufacturer-defined test conditions.
Voltage - Input (Max): Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
