The Tenma 72-8727 DSO is a four-channel digital storage oscilloscope designed to be user-friendly with a clear front panel that provides access to all basic functions for easy operation. The buttons for scaling and positioning all channels are arranged for intuitive use, based on traditional instrument practices, allowing users to operate the new unit without spending considerable time in learning and becoming familiar with operation.

The DSO features a dual time base function, which provides unrivalled waveform detail observation and analysis capabilities. The scroll display in scan mode enables continuous monitoring of signal variations. Additionally, the DSO has a unique XY mode that displays the waveform and Lissajous figure simultaneously.

The DSO supports plug-and-play USB storage devices for easy software upgrades and communication with computers through the USB device. Waveform setups and bitmaps can be stored, and waveforms and setups can be reproduced. There is a built-in FFT and multiple waveform mathematics functions, including add, subtract, multiply, and divide. The DSO also has edge, video, pulse, slope, and alternate trigger functions.

Automatic measurement of 24 waveform parameters is available for parameter testing and customization. Multiple AUTO setups provide extra flexibility.
