When I first saw Siglent's new SDS800X HD line of 12-bit Digital Storage Oscilloscopes in Saelig's email Newsletter, I was suitably impressed.
To put it in context, over a 40-year career in electronics, at work I used high-end, high-bandwidth Tektronix scopes: both analog, and later, digital models.
Electronics is also my main hobby, so I also needed a scope at home. The scopes at work cost as much as a car, so I initially settled on a used analog scope for home purposes. When the Siglent SDS1202X became available about 10 years ago, it was within my price range, so I bought one for home use.
While the Siglent SDS1202X worked great, being an early entry in the digital scope market, it didn't have a lot of the features that are present in digital scopes today. I was impressed enough with the new SDS800X HD line of scopes to ask the Saelig company to send me one to review. They kindly obliged, and sent me the SDS812X HD, which is the 2-channel 100 MHz model.
PHYSICAL FEATURES
Let's examine the physical features of this oscilloscope.
Figure 1 shows the unit on my bench. In this review, I won't make a lot of comparisons to similar competitive models.
Instead, I'll compare it to my Siglent SDS1202X, which was a comparably priced model about 10 years ago. That scope has served me very well.
The SDS800X HD line of oscilloscopes is offered in 70, 100 and 200 MHz bandwidths: I received the 100 MHz model. It uses a 7" LCD screen with a capacitive touchscreen having multi-touch capability. The screen resolution is 1024 x 600this compares to the somewhat larger 8" screen on my SDS1202X which is only 800 x 480, and non-touch. Due to the higher resolution, the SDS812X HD display is visibly sharper than my older scope.

Using Amazon Alexa to Control Custom IoT Gadgets
In part two of his article, Brian describes integrating custom IoT gadgets with Amazon Echo using emulation to receive spoken alarms. In part one, he used emulation and Arduino Cloud services as a middleman.
Holiday Hangover Hardware Hacking
Having too much cheer during the holidays? In this month's article, Colin offers a diversion from the jolly season by urging developers to retreat to the basement to brush up on hardware hacking skills. He shows how a low-cost Raspberry Pi Pico and a TP-Link Tapo C200 smart IP camera could become the next automated bird deterrent or a home automation server.
Datasheet: Microamps Per Megahertz Ultra-Low Power MCUs Minimize Current Consumption
How do chip makers differentiate if many ultra-low power MCUs on the market feature the same processor core? The peripherals and different power states offer various ways to manage current consumption down to microamps per megahertz.
Smart Home Lock Down Matter Provides Security Blanket
As more devices in the smart home connect to the Internet, they become increasingly vulnerable to outside attacks. Developers can now add the latest security measures to their Smart Home devices through Matter.
Basic Pulse Circuits
In part one of a three-part series, Wolfgang wrote how basic pulse circuits help digital circuits, such as embedded boards with ARM processors, deal with pulse trains or bursts of pulses from the outside. In Part 2, he dives into enabling flip-flops, timing parameters, and synchronization, design tasks needed to capture, detect, and filter pulses.
Building a Wi-Fi Router Watchdog
Dev created a watchdog for a Wi-Fi extender using a Raspberry Pi Pico. This monitors Wi-Fi connectivity for his smart home lighting system, which would require a reset twice a year due to rapid power interruptions.
