Technical Overview
The YB4320C is a dual-trace four-track oscilloscope designed for versatile applications in electronics engineering, education, and industrial testing. It features two independent input channels with four-track display capability, enabling simultaneous observation and comparison of complex waveforms. The device employs high-precision imported digital encoder switches, ensuring smooth operation and extended durability (5-6 times longer than conventional mechanical switches). With a vertical deflection range of 1mV/div to 5V/div and a maximum sensitivity of 1mV/div, it excels in capturing low-amplitude signals.
Key functionalities include the Alternate Expand mode, which displays both normal (×1) and magnified (×5) waveforms for detailed analysis, and the Trigger Hold feature that automates synchronization without manual adjustment. The built-in TV sync circuit supports stable display of TV-H and TV-V signals, making it ideal for broadcast equipment maintenance. The compact design (140H×335W×375D(mm), 7.2kg) balances portability and robust performance. Its horizontal scanning time ranges from 0.1μs/div to 0.2s/div (expandable to 20ns/div), covering a broad frequency bandwidth (DC to 20MHz). The instrument also includes a 1KHz±2% calibration signal output for quick self-testing.3815
功能特點(diǎn)
YB4320C提供多種觸發(fā)模式(自動、常態(tài)、TV-V/H),適應(yīng)不同信號環(huán)境。垂直工作模式包括CH1、CH2、雙蹤交替/斷續(xù)及疊加顯示,滿足多樣化測量需求。掃描系統(tǒng)采用全頻帶觸發(fā)式自動掃描電路,時間系數(shù)覆蓋0.1μs/div至0.2s/div(擴(kuò)展后達(dá)20ns/div),誤差控制在±5%以內(nèi)。設(shè)備還集成標(biāo)尺亮度調(diào)節(jié)功能,便于夜間或拍照記錄波形。
安全設(shè)計(jì)方面,輸入端口最大耐受電壓為400V(DC+AC峰值),并強(qiáng)調(diào)接地保護(hù),確保操作安全。面板布局簡潔,全部采用進(jìn)口器件,配備50Hz正弦波輸出和Z軸輸入接口,擴(kuò)展了外接設(shè)備兼容性。此外,其自動聚焦功能可在測量過程中動態(tài)校正聚焦電平,減少人工干預(yù)。2613
Technical Features
The YB4320C supports multiple trigger modes (Auto, Normal, TV-V/H) for diverse signal conditions. Vertical modes include CH1, CH2, Dual-Trace (Alternate/Chop), and Add, facilitating flexible measurements. The scanning system utilizes full-band triggered auto-sweep with a time base range of 0.1μs/div to 0.2s/div (extendable to 20ns/div) and ±5% accuracy. A scale illumination feature aids waveform documentation in low-light environments.
Safety measures include input ports rated for 400V (DC+AC peak) and mandatory grounding to prevent hazards. The front panel incorporates imported components, with auxiliary interfaces like 50Hz sine wave output and Z-axis input for expanded connectivity. The Auto Focus function dynamically adjusts focus levels during operation, enhancing user convenience.71216
