Frequency meter/counter
FY6200 provides the function of frequency meter/counter, which can measure
the frequency, period, duty cycle, positive pulse width, negative pulse width and
other parameters of external input signal. Dual channel output can work
simultaneously with the frequency meter measurement.
Enable frequency meter
Press
COUNTER
on the front panel to open the function of frequency meter
and display the setting interface of frequency meter. The measurement signal is
introduced from the input (AC coupling) or Trig.IN (DC coupling) terminal and
displayed on the screen in real time. The minimum frequency of measurement is
0.01Hz (gate time 100s).

2-1 Frequency meter / counter parameter setting interface
If the current frequency meter is turned on, you can use the stop soft key to
STOP
he screen content, and the
ZERO
soft key to set the frequency / count
value to zero.
Key Points:
The amplitude of the input signal of the frequency meter of the fy6200
series generator is greater than 1.5V, and the maximum safe input voltage of
the [counter] terminal is 20vpp. When using the function of frequency meter /
counter, please turn off the cascade function of the instrument.
