Q1 gw_product_detail_bar.png gw_product_detail_bar.png How come my digital filter function cannot use?

The digital filter function is not support under Average mode acquisition; ATL trigger; Roll mode; Segmented memory activate and the time base range setup is <=50ns/div.

Q2 gw_product_detail_bar.png gw_product_detail_bar.png How can I set frequency domain waveform display appropriately?

Please see the main frequency value on the frequency counter on the time domain. Then set this value to center frequency of spectrum analyzer function.

Please note following 3 formula to set other parameters to get the appropriate display.

  1. Center frequency=(start frequency +stop frequency)/2
  2. Stop frequency-start frequency=Span
  3. RBW=sample rate /length of FFT
Q3 gw_product_detail_bar.png gw_product_detail_bar.png Why the max. frequency range for spectrum analyzer function is 500MHz, not as same as the max. bandwidth 200MHz?

The max. frequency range for spectrum analyzer function is 1/2 of max. sampling rate which is limited at DSP Nyquist theory.

Q4 gw_product_detail_bar.png gw_product_detail_bar.png Why the frequency counter is not display on the GDS-2000E

Please check the trigger setup. The frequency counter will not display when set on Alternate trigger ;pulse runt trigger and bus trigger.

Q5 gw_product_detail_bar.png gw_product_detail_bar.png Is it worth buying an oscilloscope?

Whether or not it is worth buying an oscilloscope depends on your specific needs and application. An oscilloscope is a versatile tool that can be used to measure and analyze electrical signals in a variety of applications, including electronics design, troubleshooting, and repair. If you work with electronic circuits and need to measure waveforms, an oscilloscope can be an essential tool for debugging and validating designs.

 

If you are a hobbyist or student working on simple circuits, a basic oscilloscope with limited features and a lower price point may be sufficient. However, if you are a professional or advanced hobbyist working with complex or high-frequency circuits, you may require a more advanced oscilloscope with higher bandwidth, sample rates, and advanced analysis features.

 

Before buying an oscilloscope, it is important to evaluate your needs and consider factors such as the type of signals you will be measuring, the frequency range, and the accuracy required. You should also consider your budget, as oscilloscopes can range in price from a few hundred dollars to several thousand dollars depending on the features and capabilities.

 

Overall, if you work with electronic circuits or signals on a regular basis, an oscilloscope can be a valuable investment that can save you time and help you diagnose and solve problems more quickly and accurately.

Q6 gw_product_detail_bar.png gw_product_detail_bar.png Which is better analog or digital oscilloscope?

There is no definitive answer to whether analog or digital oscilloscopes are better, as each has its own advantages and disadvantages, and the choice depends on the specific needs of the user.

 

Analog oscilloscopes can often provide higher bandwidth and faster signal acquisition rates, making them more suitable for certain applications such as high-frequency measurements or capturing fast transient signals. Additionally, some users may prefer the "live" view of the waveform that analog scopes provide, which can make it easier to spot anomalies or irregularities in the signal.

 

Digital oscilloscopes, on the other hand, offer a number of advantages such as increased accuracy, greater flexibility, and more advanced analysis and processing capabilities. They can also store and recall waveforms, which can be helpful for analyzing complex signals or making detailed measurements. In addition, digital oscilloscopes are often more compact and portable than their analog counterparts, and can be easier to use thanks to their intuitive user interfaces and software-based controls.

 

Ultimately, the choice between an analog or digital oscilloscope will depend on the specific needs of the user, as well as their budget and level of expertise with test and measurement equipment.

Q7 gw_product_detail_bar.png gw_product_detail_bar.png What are the 2 types of storage oscilloscope?

There are two types of storage oscilloscopes (sometimes abbreviated as "DSOs" or "SSOs"):

 

  1. Analog storage oscilloscopes (ASOs): This type of oscilloscope uses a special CRT (cathode ray tube) that is capable of storing the waveform on the screen for a period of time after it has been displayed. This allows the waveform to be viewed and analyzed more closely without having to continually trigger the scope.
  2. Digital storage oscilloscopes (DSOs): This type of oscilloscope converts the incoming analog signal into digital form using an analog-to-digital converter (ADC), and stores the resulting data in memory. The stored data can then be displayed on the screen as a waveform, and can also be analyzed and processed by the oscilloscope's software. DSOs offer several advantages over ASOs, including higher bandwidth, faster sampling rates, and more advanced triggering capabilities.

Q8 gw_product_detail_bar.png gw_product_detail_bar.png What is a digital storage oscilloscope used for?

A digital storage oscilloscope (DSO) is a type of electronic test instrument used to capture and analyze electrical signals. It works by converting the analog signal into a digital format, and then storing the data in memory for further analysis.

 

DSOs are commonly used by engineers and technicians to troubleshoot and test electronic circuits, as well as in research and development to study electronic signals in various applications. They can be used to measure voltage, current, and frequency, and can display waveforms in real-time or as a captured image.

 

One of the advantages of a DSO over an analog oscilloscope is its ability to capture and store waveforms, allowing for analysis and measurement of signals that are too fast or too complex for analog scopes to handle. DSOs also offer features such as automatic measurement, waveform averaging, and signal processing capabilities that make them useful in a wide range of applications, from electronics manufacturing to automotive testing to medical research.

Q10 gw_product_detail_bar.png gw_product_detail_bar.png The EN55015 regulation primarily defines the conducted (CE) test for LED luminaires. What are the test regulations for radiated test (RE)?
The radiated (RE) test regulation EN55015 is mainly defined in the test range of 30MHz ~ 300MHz. For different test sites, the defined test regulations will be different. The test regulations of 3m can be set by referring to the test lead of EN55022A. If the test regulation of 10m is adopted, refer to the test lead setting of EN55022B.
