LT-1逻辑探头采用两个比较器鉴别被测静态电平,接成单稳工作的555型时基电路鉴别脉冲有无。该探头使用一目了然的形象符号表示信号参量的含义,显示五种基本状态,用于检测电源电压4.5伏到15伏的脉冲数字电路。
The LT-1 logic probe uses two comparators to verify the measured quiescent level, and a 555-type time-base circuit connected to a monostable to identify the presence of a pulse. The probe shows the meaning of the signal parameters at a glance, showing five basic states for the detection of pulsed digital circuits with a supply voltage of 4.5 to 15 volts.
