HP公司的1722A型示波器,是一台275兆赫新型双通道示波器。它采用发光二极管提供数字读数,可显示时间间隔、频率、直流电压、峰值或瞬时电压和幅度差的百分比。这些指示连同荧光屏显示均通过一个探头获得。其结果使精度提高,测试速度加快,人为误差减少,使用更为方便。1722A型是以该公司同类型1720A为基础的,并保持其原有技术特性。时间间隔包括:时钟相位、上升时间、脉冲宽度、周期或传播延迟等测量,其分辨率可达20微微秒。
HP's Model 1722A oscilloscope is a new 275-MHz dual-channel oscilloscope. It uses light-emitting diodes to provide digital readings that show the percentage of time interval, frequency, DC voltage, peak or instantaneous voltage and amplitude differences. These instructions, along with the screen display, are obtained through a single probe. The result is increased accuracy, faster testing, reduced human error, and ease of use. Model 1722A is based on the same type of company 1720A and maintains its original technical characteristics. The time intervals include: clock phase, rise time, pulse width, period or propagation delay measurement with a resolution of up to 20 picoseconds.
