◆ 測(cè)量參數(shù) Measure parameters:
放大倍數(shù)β(0~99)
開關(guān)時(shí)間 Switching time T (0.01μs~99.9μs),包括上升時(shí)間,存儲(chǔ)時(shí)間,下降時(shí)間 including Tr,Ts,Tf
飽和壓降 VCES (0~2V),正向壓降 VBE (0~2V)
漏電流 Leakage current ICEO (0.1μA~3mA)
耐壓 Withstand voltage BVCEO (50V~650V)
◆ 對(duì)測(cè)試的開關(guān)時(shí)間、β進(jìn)行分檔,可顯示批號(hào);對(duì)VCES、VBE、ICEO、BVCEO 進(jìn)行超限判斷,不合格的發(fā)出聲光報(bào)警,并用指示燈指明不合格項(xiàng)
Pre-set grouping values for T & β, selector can display group number and alarm when measured values of VCES, VBE, ICEO and BVCEO exceed t
he limit, meanwhile indicating the unqualified item
◆ 測(cè)試條件可按要求自由調(diào)節(jié)或設(shè)定 Freely adjustment or set of testing conditions according to requirement
A. β測(cè)試 Ib 注入電流有三檔 Three different Ib currents for β test: 0.1mA, 1mA, 10mA
B. 開關(guān)時(shí)間測(cè)試 Ic 電流有四檔 Four different Ic currents for switching time test: 0.5A, 0.25A, 0.1A, 0.05A
對(duì)應(yīng) Ib電流為the corresponding currents Ib : 0.1A, 0.05A, 0.02A, 0.01A
C. 漏電流 ICEO 測(cè)試電壓 Test voltage for leakage current ICEO: 50~650V 連續(xù)可調(diào) continuously adjustable
◆ 分檔、超限判斷可自由設(shè)定,掉電自動(dòng)保存,儀器能同時(shí)保存20組數(shù)據(jù),使用時(shí)只要調(diào)出其中一組即可
Grouping values and limit values freely set, with automatically saving function in case of power cut; the instrument can save 20 different settings,
choose one setting when using
◆ 四窗口數(shù)字顯示所測(cè)數(shù)據(jù),讀數(shù)直觀 4 windows for displaying measured values, easy to read, and printable
