Handheld

Though lightweight and portable, a handheld digital oscilloscope can perform many of the complex analysis and signal irregularity identification techniques historically reserved for benchtop units. Manufacturers such as Fluke, Keysight, and Siglent now offer pioneering handheld units that improve efficiency by bringing lab scope capabilities to the field. Handheld oscilloscopes do vary in specification. If you need to find disturbances, choose a scope with fast sampling rates and a deep memory. A four-channel digital oscilloscope means multiple signals can be reviewed simultaneously. Before selecting a field scope, take a look at the:

• Sampling rate, memory depth, and how they relate
• Bandwidth
• Channels and Count resolution
• Connectivity and data storage
• Measurement functionality
• Screen visibility
