The characteristics of this time calibration device are:
1Strong real-time performance, the device strives to achieve real-time triggering, real-time counting, and real-time output. In order to achieve real-time, a constant current trigger is used in the triggering stage, and a high-speed programmable logic circuit is used in the counting stage to form a synchronous counter, ensuring that the counting output is synchronized with the reference pulse. The output circuit is simulated using transistors.
2Adopting high-precision quartz crystal oscillator to ensure the accuracy and stability of the reference pulse.
Precautions for use:
1The pulse output mode of this device is used to test whether the instrument is accurate. It is required that the output terminal cannot be short circuited or connected to any other active output port. Otherwise, it is easy to damage the output terminal.
2When using the active internal trigger function, the active trigger terminal will have120The trigger voltage output should be around volts. Please note that the active trigger terminal should not be short circuited and should not be touched by hand.
