trigger level

The main error sources of pulse width measurement, including counter's repeatability, trigger level timing error, time base error, the amplifier hysteresis error, LSD displayed error, etc. are analyzed.

分析了脉冲信号源脉宽测量时的主要误差来源，包括计数器测量重复性、触发定时误差、时基误差、放大器滞后误差、分辨力误差等；

rx trigger level: this value sets the level at which the rx fifo buffer is filled before it is passed on to a application.

这个值设定将其传递给应用程序之前RxFIFO缓冲区充满的水平。

because the larger the event, the larger the number of oscillations of the transducer before they decay below the trigger level.

因为事件越大，传感器在它衰减到低于触发器电平之前的振荡次数越多。

And its trigger condition is cold air near ground join warm air, then develop a MCC by several small scale convective cloud under condition of upper and low level jet 、 stratification instability 、 etc.

其触发机制是冷空气从近地层楔入暖空气中，在高、低空急流、层结不稳定等诸多有利条件下，由几个小尺度对流云团合并发展成1个中尺度对流复合体（MCC）。

Health experts say that level of air pollution can trigger everything from heart attacks to stroke.

健康专家说，这样的空气污染水平可以引发心脏病和中风等各种疾病。

the trigger level is chosen on trigger signal slope side when the button is pressed.

当按下按钮时，在触发信号的斜面选择触发电平

This paper presents a new precise evaluation method for time base and trigger characteristics of digital storage oscilloscope. By using sine wave curve-fit method, the time-base, the slope of trigger, trigger level, trigger delay, and the trigger jitter have been evaluated accurately.

本文提出了一种数字存储示波器时基和触发特性的精确评价方法，通过使用正弦波拟合法，其时基准确度、触发沿斜率、触发电平不确定度、触发延时误差以及触发沿晃动被精确评价；

the two variable resistors in the center are for controlling motor speed and trigger level.

两个可变电阻的中心控制电机转速和触发电平。
