Counter (Frequency)

The 1000B Series oscilloscopes have an integrated 6- digit hardware
frequency counter.
The counter operates on the currently selected trigger source and can
measure frequencies from 5 Hz to the bandwidth of the oscilloscope.
The counter uses the trigger comparator to count the number of cycles
within a period of time (known as the gate time), so the trigger level must
be set correctly.
The frequency counter is not available in the Alternate trigger mode.
To turn the hardware frequency counter on or off:
1 Press [Meas].
2 In the Measure menu, press Counter to toggle the frequency counter
