1·The strobe signal is not commonly associated with the signal tested.

计数式频率计的选通门一般与被测信号是不相关的。

2·A clock or a strobe signal is used to synchronise operation of the comparator, the up-down counter 102 and the digital to analog converter 100 so as to avoid these components racing.

时钟或者选通信号用于比较器、递增-递减计数器102和数模转换器100的同步操作，以便避免这些部件竞争。

3·This paper analyzes usual measuring errors caused by inconsistency of the input signal pulse verge and strobe signal verge in frequency measurement. It sets forth an effective solution.

研究频率测量过程中输入信号的脉冲边沿与测量设备的闸门信号边沿不一致造成的频率测量误差。

4·PC sent signal via print control port and STROBE, encoder generated choosing signal and sent it to P3.2-end of single-chip to form interrupt.

PC通过打印机控制口与STROBE发送信号，译码器产生选片信号，传给单片机P 3.2端形成中断信号。

5·If the signal frequency to be measured is low, wide strobe gate is required for high measurement precision.

当被测信号频率较低时，需要很宽的选通门才能得到较高的测量精度。

6·Functional and in bright light, low light, strobe, SOS distress signal in the recycling.

功能齐全，能在强光、弱光、爆闪、求救信号SOS中循环使用。
