Counter

The InfiniiVision 4000 X- Series oscilloscopes have an integrated hardware
frequency counter which counts the number of cycles that occur within a
period of time (known as the gate time) to measure the frequency of a
signal.
The gate time for the Counter measurement is automatically adjusted to
be 100 ms or twice the current time window, whichever is longer, up to 1
second.
The Counter can measure frequencies up to the bandwidth of the
oscilloscope. The minimum frequency supported is 1/(2 X gate time).
