14 Measurements
Counter
The InfiniiVision 3000 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).
The hardware counter uses the trigger comparator output. Therefore, the
counted channel's trigger level (or threshold for digital channels) must be
set correctly. The Y cursor shows the threshold level used in the
measurement.
Analog and digital channels can be selected as the source.
Only one Counter measurement can be displayed at a time.
