Siglent Oscilloscope Review

Siglent Sds1202X-E Super Phosphor Oscilloscope

SDS1202XE is a Super Phosphor Oscilloscope 2CH 200MHz with a maximum sampling rate of 1GSa/s. It also has a standard 14Mpts record length. The user-friendly design of the front panel makes it easy to access all commonly used functions. The SDS1000X-E Series employs a new generation of SPO (Super Phosphor Oscilloscope) technology that provides excellent signal fidelity and performance. System noise is lower than other products in this industry. The system features a minimal vertical input range at 500 uV/div and an innovative digital trigger system that has high sensitivity, low jitter and captures waveforms at 400,000 frames/sec in sequence mode.

Additionally, the SDS1000XX-E features a 256 level intensity grading display function as well as a colour temperature display mode that is not available in any other model in its class. SIGLENT’s most recent oscilloscopes offer multiple powerful trigger modes, including serial bus-triggering. Serial decoding can be done for free, and it includes IIC and SPI as well as UART and CAN. Extended waveform analysis and recording can be done using sequential triggers and history waveform recording. The new 1 Mpt FFT mathematics function gives the SDS1000XE extremely high frequency resolution for observing signal spectrums. The new design also includes a hardware co-processor that delivers measurements quickly and accurately. The features and performance of SIGLENT’s new SDS1000X-E series cannot be matched anywhere else in this price class.

DIY Kits for Toy Oscilloscopes and Oscilloscopes

Toy and DIY oscilloscopes are available for those who can not afford an expensive oscilloscope. These tools may not be as precise as an actual oscilloscope, and they don’t offer all of the mathematical functions. However, they are still very useful.

One of the best options is the DSO150 digital oscilloscope. It is a basic scope that costs only $25 and has a single channel with 200kHz bandwidth and 12 bit resolution. Although this tool isn’t meant to replace an oscilloscope in real life, it can be used by hobbyists who need to troubleshoot circuits that require accuracy. Also, this can be a great tool for learning purposes. Check out our video review or read our review.

Another alternative is the DSO138. Its specs are similar to the previous scope: single-channel, 12-bit resolution, 200kHz bandwidth. However, this scope is a DIY kit. You can get the scope assembled in an acrylic housing. Personally, I prefer the previous scope because the controls seem more intuitive to use. It is only a personal preference.

Siglent Technologies Sds1202X-E Digital Oscilloscope- The Best For A Large Display!

A DSO is an incredibly valuable instrument for those new to the technological field concerned, e.g. mechanics, electronic technicians, nursing, physicists, auto repair, etc., involving electronic signal capture and documentation for thorough analysis and contrast of various sources.

This scope can be used to launch a digital o-scope journey for less than $500, and it has enough bandwidth to handle complex signals.

The color temperature monitor and 256 strength grading are specs of the Siglent SDS1202X-E, which you can’t find in other versions in this class. Under this feature, the occurrence of the trace is well reflected by various colors of differing temperatures, instead of only one color changing in strength. The higher frequency occurrence is expressed in the red shades, while the blue represents the opposite end.

The most important parameters are 4 channels and a sampling rate of 1 Gsps per channel. Input bandwidth is 50 MHz.

A great starter oscilloscope. There are all really strong specifications for the price as opposed to rival models. As an extra, you get four free software choices nowadays, including a 24 Mpts memory expansion, an advanced trigger option, RS-232, I2C and SPI protocol decoders, and a record module. This makes the device very appealing.

Bandwidth starts at 50 MHz. It can also be increased to 100 MHz. The depth of the memory ranges from 12 to 24 Mpts. Some devices may offer free tools at higher frequencies. These can be used to collect data via USB, and then perform FFTs on your CPU. Furthermore, the DS1054Z will allow the full-screen XY monitor with only some firmware updates.

The Pros and Cons of Siglent Technologies Sds1202X – E

It is effortless to use and has a good layout

Amazing accuracy, able to validate even complex devices.

Probably the only one that provides 200 MHz bandwidth at this price

With its powerful features, including FFT, serial decoding, and saving to USB, it comes at no extra cost

A measure of how many bits are in a sample is the impressive sample rate

Even though they are simple, math functions can be used easily.

Two channels are sufficient for hobbyists, however.

It can be a bit tricky to set the trigger position exactly where you want it.

Types:

1) Analog devices

The analog oscilloscope is the device where measured voltage will show on the in-built computer. This voltage has the job of deflecting the current, and a waveform is then automatically obtained.

2) Digital oscilloscopes (DSO)

Lightweight and portable

The highest bandwidth range;

Colored displays with high resolution;

Printing and storage features;

User-friendly interface;

Modern DSOs may also be entirely implemented into Automated Test Equipment (ATE) systems with their PC networking. The DSO can also be used to front-end a device that acquires high-speed data. This makes it economically more feasible.

3. USB-based devices

O-scopes that have USB connections may not come with a monitor, as the data can be seen directly on the computer. This type of product is more affordable and will satisfy many who don’t want to purchase professional products. USB oscilloscopes can have extremely limited input voltages.

Compatible Probes

Any o-scope and the probe function work as a single system, so when choosing this device, make sure to remember the probes. Probes actually become a part of the circuit during calculations, adding resistive, capacitive, and inductive loading that changes the calculation.

To minimize the effect, it is better to choose probes that have the right optimization for your scope. Choose passive probes that have appropriate bandwidth. You should have the same bandwidth as the oscilloscope.

There are several types of probes available:

Passive probes are the most common probes used for every input channel. They are required for ground-referenced measurements;

When it comes to taking differential measurements, high-voltage probes can be precise and floating.

Current probes are used for measuring current and instantaneous power;

Accuracy and Resolution

In visual technology, a signal shift of 1% is not a concern, however, in audio electronics, distortions or noises up to 0.1 percent can cause serious problems. Modern DSOs, digital o-scopes, are optimized for speedy digital signals. They provide 8-bit ADC (8-bit ADC), so that a signal shift of 0.4 percent can be seen at its best.

The voltage spectrum is broken into 256 vertical phases (28 = 256) with 8 bits. This correlates to around 8 mV per phase, with a +-1 V range selected. This may be sufficient to display digital signals, but leave much to be desired, particularly when utilizing the feature of the spectrum analyzer, to view analog signals (if it has any).

High resolution (12 bits or more) and high DC accuracy oscilloscopes are often referred to as precision o-scopes.

Tips For Buyers:

Before you buy, make sure to test out a few of the o-scopes. Look for online sales that offer a money back guarantee.

Get demos and samples for a certain device. Make sure the demos feature the true signals you want to test with higher cost scopes, not just signals that display the scope in a positive light;

When purchasing scopes, ask about upgrades and verify the price. Be sure the program is included and ask if you would have to compensate for software updates for PC-based scopes. The cost of attaching cables to printers/PCs for benchtop scopes can be added 50 percent;

Verify the duration of the warranty. If your device fails to use, the manufacturer should cover the repair costs;

Number Of Channels

You’ll have to equate two or three signals often. It is possible to do this only if your system supports multiple channels. Multiple scopes can simultaneously display multiple signals on the computer.

A separate channel is fed into any signal read by a scope. The signals are therefore seen side by side and can be contrasted easily.

This is why o-scopes that have more channels seem to be more expensive. You can use this information to help you decide whether to display two or four signals channels.
