- The reference current at HREF also defines the integration time constant of the vertical sync integration. 叁考涌流在 HREF 也定义整合时间垂直同步整合的常数。
- Rise time in a feedback picoammeter is a function of the physical or stray capacitance shunting the feedback resistance (RFB). 反馈型皮安计的上升时间是反馈电阻(RFB)上并联的物理电容或寄生电容的函数。
- Suitable for high stablity circuits,such as oscillatory circuits and time constant circuits,etc. 树脂包封标准品,稳定性高。适用于高稳定线路,如振荡回路、时间常数等回路。
- Due to the high degree of voltage amplification, this stage regenerates the voltage swing and the rise time of the incoming signal. 因电压放大的高倍数,这一级一则改变输入电压的摆幅,二则改变引入信号的上升时间。
- Pulse power with fast rise time technology was applied in many fields such as nuclear physics, electron beam, accelerator, laser, HPM etc. 高压大电流快脉冲技术在核物理技术、电子束、加速器、激光、HPM等许多现代科学技术领域都有广泛的应用。
