In this segment, the focus is on reviewing the features and functionalities of a budget oscilloscope. It mentions the device’s USB and LAN capabilities, along with a USB-C power input, which is a point of contention for some users. The device has a power consumption of 36 watts and can be powered by an external battery pack. The video highlights the inclusion of a quality plug pack, ergonomic design, and a capacitive touch screen with gesture controls. However, the boot-up time is quite long at 46-47 seconds.
The unit’s operating system is on a Micro SD card, allowing for modifications, and there are known hacks to upgrade its model. Despite having a single USB output, it can support a hub, mouse, and other peripherals. The oscilloscope does not support advanced probes but can handle basic input impedances and has several useful measurement capabilities and self-calibration features. It also has a range of trigger options and diagnostic functions, though some controls and indicators could be clearer under lab lighting. Finally, the segment addresses some quirks, such as a warm smell during operation, and peculiar behavior when certain features are activated, which appears to be an architectural limitation.

In this part of the video, the presenter discusses the performance and features of a low-end oscilloscope. The scope supports up to 1 million waveform updates per second in Ultra Acquire mode and is noted for its responsiveness and compact design, which is significantly smaller and lighter than the older 1054Z model. The new oscilloscope boasts the same seven-inch screen size but with higher resolution and more efficient use of space, featuring vertical controls. It inherits several advanced features from the higher-end Rigol 4000 series, including a 12-bit analog-to-digital converter across all channels, but it lacks certain capabilities like a digital logic analyzer and arbitrary waveform generator. The waveform update rate is highlighted, with a maximum of about 27,000 updates per second, and the rate remains consistent across various settings. The user interface is praised for its interactivity, including features like pinch-and-zoom and customizable waveform display. The presenter demonstrates the FFT (Fast Fourier Transform) function, noting its capability and ease of use, although it lacks some advanced functionalities. Overall, the oscilloscope is deemed impressive for its low price, offering robust features and performance typically seen in higher-end models.

In this part of the video, the presenter compares the performance of different oscilloscopes with various settings. They discuss the differences in response between 8-bit and 12-bit ADC (Analog-to-Digital Converters), demonstrating how the higher resolution of 12-bit ADCs can discern smaller details in signals. The presenter evaluates a 30 millivolt peak-to-peak signal within an 80-volt range and highlights how the 12-bit ADC manages to pull signals well above the noise floor, which is something the 8-bit ADC struggles with.
The presenter then tests different frequency modulations with various settings and compares the noise floors of the oscilloscopes. The Rigol oscilloscope shows better results than the Siglent across these tests, having superior signal clarity and lower noise. The comparison also shows that the Rigol has a better front-end pulse response and input microphonics performance.
Additionally, the segment discusses the record function of the oscilloscopes and how it can quickly capture multiple frames. The presenter demonstrates setting up the delayed trigger and using the quick button for recording different frames, showcasing the ease of use and the capability to capture infrequent glitches effectively. The presenter also touches on the ability to save images and waveforms quickly using USB sticks and managing recorded data despite some minor inconveniences like the lack of a real-time clock in the device.
