Siglent SDS1202X-E Review

Digital oscilloscopes have become irreplaceable parts of different companies and industries since the last century. This has resulted in numerous different developers coming up with new products. While this is great, all the different options can be quite confusing!

This is even tougher for beginners to decide which product to get. So we bring you the Siglent SDS1202X-E review, in order to help out with your purchasing decision. This is truly a decent digital oscilloscope at a low price, and should definitely be checked out.


Siglent Technologies SDS1202X-E 200 mhz Digital Oscilloscope 2 Channels, Grey

Siglent is now a global company with its headquarters in Shenzhen, China. They have been successfully producing electronic testing and measurement equipment at reasonable prices. The Siglent SDS1202X-E is one of their lower ends, yet fully functional digital storage oscilloscopes.

Equipped with a bandwidth of 200 MHz, this oscilloscope can measure signals accurately. The bandwidth, along with the sampling rate of 1GSa/s, makes this a very apt device for capturing both instantaneous and repeated signals. As the memory depth on this product is 14 Mpts, you needn’t worry about data storage!

This unit also contains a serial decoder for easy isolation as well as analysis of events. The display on this product is very nice due to the 7-inch WVGA LCD screen, which makes it large and easy to read. As a bonus, the screen is coated so that it is non-reflective, which makes it easier to work with

If you are wondering about the trigger options, this device has an innovative trigger system. The technology on the SDS1202X-E is also very impressive as it contains Super Phosphor Oscilloscope (SPO) technology.

This helps in the accurate measurement of the signals, which are then displayed on the screen.
Gate and zoom measurement is another great feature on this device. This feature allows errors in measurements to be avoided and helps increase the validity of the measurements.

Masked Pass/Fail Tests can also be performed by the SDS1202X-E, which gives this oscilloscope a full set of features at a low price! Now last but definitely not the least is the design! This product has a very ergonomic design with a handle for carrying it.

The SDS1202X-E contains all of these great features while at the same time being easy to use by beginners. What more could you ask from an entry-level DSO?!

Key Features

Here we have the standout features of the Siglent SDS1202X. Read on to learn more about this product:


This device is a DSO with a bandwidth of 200 MHz, which is very impressive on its own, not to mention on an entry-level device! The long bandwidth range allows it to be used with a lot of devices with ease, including complex devices.

Only 2 channels are included, however, and even though they are of high quality, they will not be enough for non-entry level users. The real-time sampling rate is 1GSa/s, which is enough for capturing accurate signals.


The SPO technology makes for fast refresh rates as well as accurate measurements. As it contains Fast Fourier Transform (FFT) as well, it can perform spectrum analysis, which is very convenient. It also contains Zoom technology, which is hardware-based.

This enables the capturing of more signals with a record length of 14 Mpts. It also allows you to zoom in on certain areas, in order to be better focused.

Display and Design

The WVGA LCD display on this device is 7-inches in diameter, with a resolution of 800×480. This makes for very easy reading of waveforms, especially due to the color temperature display.

As mentioned above, this device has a design that is efficient for use, including the fact that the screen also is tilted up for ease of viewing! Not only that, but it also contains buttons that are cool-lit, meaning that they are lit without any lights.


Measurement of siglent oscilloscope

As is common with many digital oscilloscopes, this one also contains auto measurement capabilities for up to 5 parameters at the same time.

These include amplitude, rise and fall time, duty cycle, and pulse width, amongst others. Statistics are shown for the measurement of each parameter, which is quite convenient. A plus point of the SDS1202X-E is that it has very low system noise.

This means the amplitudes and phases of the signal waves are not going to be modulated, giving very accurate measurements.

Easy of Use

As it is an entry-level digital oscilloscope, the SDS1202X-E is very easy to use. It contains a help system for beginners that are built into the system for free.

Additionally, the layout of the buttons is very conveniently placed, which also makes it easy to use.
