Online UPS provides continuous power to critical equipment, eliminating downtime during power outages. It offers protection against voltage fluctuations, spikes, and surges, making it ideal for data centers, hospitals, and other sensitive applications.
It is designed to protect sensitive electronics and prevent data loss or damage caused by sudden power disruptions.The primary function of an inverter UPS is to convert DC (Direct Current) power from a Battery into AC (Alternating Current) power that can be used by electronic devices. This conversion is achieved through the use of an inverter, which changes the battery's DC power into the AC power required by the connected equipment.
Our Bosin Inverter with UPS function power frequency energy-saving transformer with full-bridge pure sine wave output, low loss and high efficiency.They can unattended duty-free function may also offer the ability to remotely manage and control the UPS, allowing users to monitor its status, perform diagnostics, and configure settings from a central location.Support a variety of communication interface, remote monitoring via RS232/mobile App/Wi-Fi/GPRS.Automatic start when city power comes.It has three working model:Grid prior, Eco mode, PV prior.
One of the key features of an inverter UPS is its ability to provide uninterrupted power during a blackout. When the main power supply is interrupted, the UPS automatically switches to battery power, ensuring that connected devices continue to operate without any interruption. This seamless transition is crucial for systems that cannot afford any downtime, such as servers, medical equipment, or communication networks.

Detailed explanation of the oscilloscope's DDC (digital down conversion) technology
In today’s world, electronic product design is becoming increasingly complex, and so are the testing requirements. Engineers no longer just need to analyze signals in the time domain; they also require insights into frequency domain characteristics or even joint analysis across multiple domains. As a result, test benches often become cluttered with various instruments such as oscilloscopes, spectrum analyzers, and more. This not only takes up valuable workspace but also makes the testing process complicated due to the need for synchronization between different devices.
To simplify this, there is a growing demand for multi-functional instruments that can perform time-domain measurements, frequency-domain analysis, and even time-frequency domain signal processing—all in one device. Oscilloscopes, being the most commonly used tools, have great potential if they could integrate these advanced analytical functions. Many manufacturers have introduced all-in-one oscilloscopes, but they often rely on software-based calculations rather than hardware integration, leading to limitations in performance.
One of the main challenges in traditional oscilloscopes is the trade-off between resolution bandwidth (RBW) and capture time during spectrum analysis. A smaller RBW provides finer frequency resolution but requires longer capture times, which reduces the sampling rate and limits the ability to analyze high-frequency signals. Conversely, higher sampling rates reduce RBW and weaken frequency resolution. Additionally, vector signal analysis is constrained by limited memory and sampling rate, making long-term signal analysis difficult.
This is where DDC (Digital Down Conversion) technology comes into play. R&S oscilloscopes utilize DDC to convert high-frequency RF signals to baseband, allowing for efficient data handling and improved signal processing. By downconverting and resampling the signal, DDC enables better use of memory and faster processing, solving many of the limitations faced by traditional oscilloscopes.
The DDC process involves generating a local oscillator signal using an NCO (Numerical Control Oscillator), mixing it with the incoming RF signal, and then filtering and resampling the resulting baseband signal. This approach significantly reduces the amount of data that needs to be processed, improving efficiency and enabling longer signal captures.
R&S oscilloscopes implement DDC at the hardware level, providing real-time signal processing capabilities. This allows them to maintain high sampling rates at the front end while reducing the data load after conversion. For example, when analyzing a 300 MHz modulated signal with a 2 MHz bandwidth, traditional oscilloscopes would limit the capture time to around 16.6 ms. With DDC, the same signal can be captured for up to 2.5 seconds, offering a 150x improvement in acquisition time.
In I/Q demodulation, DDC helps extract the baseband components of a signal efficiently, eliminating the need for post-processing in software. Similarly, in spectrum analysis, DDC allows for precise frequency resolution without sacrificing sampling rate or risking aliasing. This makes it possible to achieve high-resolution spectral analysis even for high-frequency signals.
Overall, the integration of DDC technology in R&S oscilloscopes enhances their versatility, performance, and usability, making them ideal for modern signal analysis tasks. Whether for debugging, testing, or research, these instruments provide a powerful solution for multi-domain signal analysis.
