Frequency Counter
DG800 provides a frequency counter which can measure various parameters (e.g.
frequency, period, duty cycle, positive pulse width, and negative pulse width) of the
external input signal and make statistics of measurement results. When the
statistical function is enabled, the instrument calculates the maximum, minimum,
average, and standard deviation of the measurement values automatically and
displays the variation tendency of the measurement values in "Digital" or "Curve"
mode. In addition, CH1 output can work normally while the frequency counter is
making measurements.
To Enable the Frequency Counter
Press Counter on the front panel (the backlight turns on) to enable the frequency
counter function and enter the frequency counter setting interface.

If the frequency counter is currently turned on and the screen displays the frequency
counter interface, press Counter again to disable the frequency counter function. If
the frequency counter is currently enabled and the screen displays interfaces other
than the frequency counter interface, press Counter again to switch to the
frequency counter interface.
Note:
When the frequency counter is enabled, the output of CH2 will be disabled.
