What Are Handheld Oscilloscopes and Why Do I Need Them?

An Oscilloscope is a piece of laboratory equipment commonly used to graphically display and analyze various lengths of voltages, wavelengths, etc. Heartbeats can be compared to the oscilloscope in the sense that we don’t want the heart to beat too fast or slow.

We want to be able to use the heart rate monitor and see that everything is functioning well. The oscilloscope ensures that voltages of an object oscillate at the right pace or frequency. No glitches in devices are practically what the oscilloscope provides.

About the Oscilloscope

A typical oscilloscope can display alternating current or pulsating direct current waveforms having a frequency as low as approximately 1 hertz or as high as several megahertz. High-end oscilloscopes can display signals having frequencies up to several hundred gigahertz.

The display is segmented into what is called horizontal divisions and vertical divisions. Time is shown from left to right on the horizontal scale. Instantaneous voltage appears on the vertical level, with positive values going upward and negative values going downward.

The oldest generation of the oscilloscope, still used in some labs today, is known as the cathode-ray oscilloscope. It produces an image by causing a focused electron beam to travel, or sweep, in patterns across the face of a cathode ray tube.

More modern oscilloscopes electronically replicate the action of the CRT using a liquid crystal display, which is what is found in some computers, smartphones, and tablets. The most sophisticated oscilloscopes employ processors to process and display waveforms. These computers can use any display type, including CRT, LCD, and gas plasma.

In virtually every oscilloscope, there are horizontal sweep and vertical deflection settings that are adjustable to various preferences. Horizontal sweep is measured in seconds per division, milliseconds per division, microseconds per division, or nanoseconds per division. The vertical deflection is measured in volts per division, millivolts per division, or microvolts per division.

Significance of Oscilloscopes

When it comes to viewing electrical signals and waves, most times the time-varying ones, an oscilloscope is the choice of equipment. The messages will either arrive at a slow or rapid pace. The oscilloscope has amplification and delay features that allow part or all of the signal to be observed. Other features enable the messages to be physically moved about the screen. All of this makes it easier for the signal to be measured for whatever purpose it’s being used for.

What is it used for?

The different uses for an oscilloscope are copious as it useful for many things. It can be used to view the signals coming directly from devices such as sound cards, allowing the real-time display of waves. They are used in the hospitals for electrocardiograms, to test circuits of varying sizes and types. It is also involved in the fixing of devices such as televisions as it regards to troubleshoot. Oscilloscopes with storage features allow signals to be captured, retrieved and analyzed for later use.

With handheld oscilloscopes, performing activities would be more convenient as you wouldn’t have to stay in one place to achieve the task. You can move with the equipment to carry out other tasks. The oscilloscope is also very versatile and among the most frequently used equipment.

Automotive technicians use oscilloscopes to diagnose electrical problems in cars, while university labs use oscilloscopes to teach students about electronics. One the other hand, the military and aviation industries use oscilloscopes to test radar communication systems. And R&D engineers use oscilloscopes to test and design new technologies.

An oscilloscope is a valuable tool as it can be used for many purposes. Some of the tasks it performs are more important to us than we realize as, without it, life would be considerably more difficult.
