Oscilloscopes are mainly electronic instruments used to graph the change in electrical signal over time. This is important for designers and technicians, as oscilloscopes help understand and fix electronic systems. The Owon model has 4 common types of oscilloscopes that differ primarily in important specs like their signal capture abilities. They are digital storage oscilloscopes, hand-held oscilloscopes, PC-based oscilloscopes, and mixed domain oscilloscopes. The important features of these types are discussed in the following sections in detail.
DSOs digitize and store signal waveforms, allowing users to analyze captured errors. Adjusting the time base and voltage per division lets users view the stored waveforms at different signal speeds and sizes. Features like auto-scaling and advanced math show how adjusting the time base and divisions helps work with different signal types. For example, a 100MHz DSO can capture fast signals, while a 4GSa/s sample rate can freeze a signal for detailed inspection. Overall, the storage, analysis features, and higher sample rate are good for users who test complex signals, making DSOs better than older oscilloscopes that only show the current signal, which is good enough for basic work.
HSOs are portable and ideal for testing equipment outside the lab. For example, an HSO measuring 200MHz can help check fast signals, while a battery can last hours in the field. An HSO weighing over 2kg is easy to carry and run without AC power. Autoscale and built-in memory let a technician store results to fix problems faster while on site. Consider a tech checking wiring in a car where the HSO finds a signal fault faster than plugging into a lab scope. Field-ready features enable clients to test effectively beyond labs.
A PC-based oscilloscope connects to a computer, enhancing it with waveform monitoring. This setup provides a wider display and storage than traditional scopes. For instance, a colleague checks signals on a 1920x1080 monitor using a 100MHz scope. The big screen helps spot signal issues better than a small lab scope. Software tools also let her save and analyze data on the PC. Data from a 20MS/s scope is easily managed by a laptop. The combination allows for easy use and in-depth analysis lessened by hardware limits.
MDOs track both analog and digital signals. This dual use helps test systems using both types. For example, a colleague monitors 100MHz analog and 16 digital channels at once. One device simplifies working on hybrid systems. MDOs are useful for testing things like Displays, which have analog video and digital control signals. This integration speeds up troubleshooting and verifies that all system parts work. MDOS lets users do comprehensive testing without needing separate tools for analog and digital.
The specifications mainly refer to the features and functional characteristics of a product, which help compare products. The key specifications of the Owon oscilloscopes are listed in the following subsection in detail.
Bandwidth indicates the speed of signals the oscilloscope can measure. Higher bandwidth means it can capture faster waveforms without distortion. This is key for testing high-speed circuits or fast signals. For example, an oscilloscope with 100MHz bandwidth captures a 100MHz signal accurately. If the bandwidth is too low, it cannot display the signal shape correctly. The recommended bandwidth is generally set at 2.5 times the highest signal frequency captured. Oscilloscopes with more bandwidth are preferred by clients for their work with complex high-speed signals.
The sample rate shows how fast the oscilloscope records data points on the signal. A higher rate captures more detail, which is especially important for fast-changing signals. This is key for high-precision testing. For example, a sample rate of 1GSa/s means it records 1 billion samples per second. This allows for a more accurate display of the signal waveform on the screen. If the rate is too low, the waveform may appear flat or undersampled, missing important signal variations. To capture all signal details, select a sample rate at least 2–4 times the bandwidth of the signal being measured.
Input sensitivity determines the smallest voltage the oscilloscope can measure. Greater sensitivity enables it to capture minor signal fluctuations precisely. This is vital for testing low-voltage circuits or observing small noise levels. It is key for designs concerned with small signal measurements. For instance, an oscilloscope with 1mV per division captures signals as small as 1mV. Lack of sensitivity may cause small signals to vanish or appear incorrectly. Select an oscilloscope with greater sensitivity to verify all key measurement requirements.
Memory depth shows how long the oscilloscope can capture data for analysis. Greater depth allows one to store more points per trigger, enabling detailed examination of complex waveforms. This is particularly useful when capturing long signal transients or rare signal faults. For example, a depth of 1Mpoints lets one see more of the waveform and make better determinations on it. Limited memory may cut off key signal details. Select one with adequate memory for effective capture of infrequent or complex waveform patterns.
It is very important to understand where and how a product is used to help compare different products and their efficiency. Below are the important usage scenarios of Owon oscilloscopes based on different professional domains.
Engineers frequently test circuits by comparing actual and expected signals with an Owon oscilloscope. If the signal does not match, it shows that there is some issue in the circuit that needs to be fixed. They use the oscilloscope's high-speed capture to observe waveform changes. This helps in understanding circuit behavior. Signal analysis tools let them check if signals meet specification levels. The customizable screen shows multiple signals together for in-depth comparison without switching views. They choose this scope for accurate low-noise signal capture to maintain circuit design fidelity.
Field technicians use an Owon oscilloscope to troubleshoot malfunctioning equipment. Its portability enables quick readings of key signals away from the lab.
