When it comes to visualizing high-speed signals in all areas of modern electronics, the basic gadget that comes into the picture is an Oscilloscope – An indispensable electronic testing device that displays a two-dimensional plot of signals as a function of time. With the advent of technological improvements, the potential demand of the oscilloscopes is increasing in a tremendous manner as they are used by Electronic Hobbyists, High School & College Laboratories, Industrial Sector and so on. A wide variety of Oscilloscopes include the Analog Oscilloscopes, Digital Storage Types, Hand-Held Oscilloscopes etc., are available in the market from various manufacturers for different applications with altering price ranges. The following SIGLENT SDS1202X-E review gives an in-depth essence of SDS1202X-E Digital Oscilloscope.

This is an ultra-entry level digital oscilloscope under SDS1202X-E Series. It features 200 Mhz Bandwidth and two input channels (1MΩ, 18pF, 400Vpeak) with a sampling rate of 500Mega Samples per second. The all-new SDS1202X-E comes with Super Phosphor Technology (SPO), which commits the user with unmatched performance and signal accuracy so that an ultra-precise visualization of the output signal is displayed in a 7-inch TFT LCD screen of 800×480 display resolution.
In general, certain factors that assess the good quality of a digital oscilloscope are –Bandwidth, Memory Depth, Resolution, Audible Noise, Waveform Update Rate, Cost etc., This Oscilloscope is not an exception to the above parameters.
BANDWIDTH: A fundamental factor that determines the oscilloscopes capability to measure a signal. For SDS1202X-E the value of Bandwidth is 200 Megahertz, which suits exactly for all low & mid-frequency signals and occasionally works for high-speed complex signals.
MEMORY DEPTH: Mathematically, memory depth is defined as the multiplication of sample rate times the acquisition time window. i.e.
MEMORY DEPTH = SAMPLE RATE X ACQUISITION TIME WINDOW
The SDS1202X-E has a memory depth of 1 Giga Samples per second for single channel and 500 Mega Samples per second for dual-channel. Obviously, we could say that with 500MSa per channel, the SDS1202X-E can capture 500ms of time with a 1GSa/s sample rate. It captures input signals at a much faster rate.
RESOLUTION: It determines the level of comminution of measurement that can be made with the waveform without clipping. Digital Oscilloscopes with Higher Resolution levels will offer more small signal detail and it is indispensable for more accurate timing measurement when the signal changes. The SDS1202X-E can have a resolution score of 28 (256 Levels)
AUDIBLE NOISE: Due to various active and passive electronic components present inside the circuit board of a digital oscilloscope, it generates some form of noise. SDS1202X-E has no great number of fan noise (the noise generated by the cooling fan inside the cabin of an oscilloscope) and its observed value is 49.4dB. No annoying sound will be there at the time of operation.
The Heart (or) the main architecture of SDS1202X-E is the Zynq-7000 SoC as the core processing chip from Xilinx, which embedded the features of a typical high-end digital oscilloscope into this entry level scope. It has a dual ARM cortex series processor for the Processor System (PS) and Artix 7 based FPGA as the Programmable Logic (PL). The PS and PL are connected through the AXI high-speed bus, which intelligently eliminates the use of individual motherboards and all the circuitry can be found in a single compact Motherboard with a multi-layered PCB (Printed Circuit Board). Here, the FPGA is combined with the ARM Processor having a 1Mpoints FFT in the form of Ball Grid Array (BGA) IC.
Apart from the main processor, Analog Device’s HMCAD1511 is used as the High-speed Analog to Digital Conversion Chip for processing the analog inputs. For the memory and storage, single-chip DDR3 (Double Dynamic RAM) interface is used in parallel with Zynq-7000 SoC. The main feature in SDS1202X-E is the digital triggering with various modes like Edge Trigger, Slope Trigger, Pulse Trigger, Video Trigger, Window Trigger, Interval Trigger, Dropout Trigger, Runt Trigger, Pattern Trigger and Serial Communication Trigger. It also supports various math and windowing functions with a rise time of 1.8 nanoseconds.
It comes with USB interface for storing the data on a Thumb Drive/Pen Drive Storage where the data is stored in .png (Portable Network Graphics) format by inserting one storage into the front USB Port and pressing the Print/Save Button.
Other ports like including the LAN, EXTERNAL TRIGGER & USB COMMUNICATION Port are present on the rear side of the oscilloscope. Separate Software CD Packages are provided & are used to visualize the data in Laptop/Desktop PC by synchronizing the scope with any one of the above-mentioned methods.
Finally, with all the above-mentioned features and technical specifications. It is an absolute digital storage oscilloscope for any who interested in electronics and well suits for hobby projects. It also comes with a set of probes within the box along with various attachments.
