Frequently Asked Questions
What makes 12-bit resolution so valuable compared to standard 8-bit oscilloscopes?
The 12-bit ADC in UNI-T's HD series provides 4,096 quantization levels—16 times more than the 256 levels in conventional 8-bit oscilloscopes. This higher resolution reveals signal details that would otherwise be lost in quantization noise, enabling engineers to observe small signal variations within larger waveforms. For applications like power electronics, where accurately measuring small ripple components on DC voltage rails is critical, or in precision analog circuits where subtle signal variations contain important information, this enhanced resolution delivers significant advantages.
How does the zone trigger feature simplify capturing complex signal events?
The zone trigger function revolutionizes the process of isolating specific signal events by allowing engineers to visually define regions of interest directly on the screen. Rather than configuring complex combinations of conventional trigger parameters, users simply draw rectangles around the signal areas they want to capture or exclude. The oscilloscope then triggers only when signals enter, exit, or remain within these defined zones, making it remarkably easy to isolate irregular signal patterns.
Can UNI-T HD series oscilloscopes be integrated into automated test environments?
Yes, both the MSO3000HD and MSO5000HD series are designed for seamless integration into automated test systems through multiple connectivity options and comprehensive remote control capabilities. The instruments support both LAN (VXI-11) and USB interfaces for physical connection to test controllers, and include a built-in WebServer that enables browser-based instrument access and control. Both series fully support SCPI (Standard Commands for Programmable Instruments), providing a standardized command interface for automated operation.
What advantages does the built-in function/arbitrary waveform generator provide?
The optional dual-channel function/arbitrary waveform generator transforms your HD oscilloscope from a passive measurement tool into an active test solution. With 50 MHz performance, 16-bit vertical resolution, and a comprehensive library of built-in waveforms, this integrated generator eliminates the need for a separate stimulus instrument in many applications. When combined with the Bode plot analyzer function, the integrated generator enables complete closed-loop testing of power supplies, filters, and amplifiers without additional equipment.
Which HD series is better for power electronics applications?
Both the MSO3000HD and MSO5000HD series excel in power electronics applications, but with different strengths. The MSO3000HD series offers excellent 12-bit resolution and optional power analysis capabilities at more accessible price points, making it ideal for general power electronics development. The MSO5000HD series adds higher waveform capture rates, more comprehensive protocol support, and enhanced display technology, providing advantages for advanced power electronics with GaN or SiC devices or systems with multiple communication buses. For most power electronics applications, the MSO3034HD (350MHz) or MSO5034HD (350MHz) provides an excellent balance of performance and value.
