Time Measurements
The default lower, middle, and upper measurement thresholds are 10%, 50%, and 90%
between Top and Base values. See “Measurement Thresholds” on page 197 for other
percentage threshold and absolute value threshold settings.
The following figure shows time measurement points.
Counter
The InfiniiVision 7000 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).
FFT measurements
When you make an X at Max Y or X at Min Y measurement on a math FFT function, the resultant
units will be in Hertz. No other time related automatic measurement can be made on the FFT math
function. Use the cursors to make other measurements on FFT.
