Frequency Counter Measurement

The hardware frequency counter supplied with DS1000Z-E oscilloscope can make

more precise measurement of the input signal frequency.

Press Measure  Counter to select one of the channels (CH1-CH2) as the

measurement source. The measurement result is displayed at the upper right corner

of the screen and you can identify the current measurement source according to the

color of the icon and channel number. The following figure is the result of the

frequency measurement of the input signal of CH1.

Select "OFF" to disable the frequency counter measurement function.

Note: When the frequency of the input signal of the measurement source is lower

than 15 Hz, the measurement result is displayed as "<15Hz".
