Making Time Measurements Automatically - Agilent Technologies 54621A User Manual

Making time measurements automatically

FFT measurements
When you make an X at Max or X at Min 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.
Measurement thresholds for time measurements
The default lower, middle, and upper measurement thresholds are 10%, 50%, and
100% between Top and Base values. See the previous topic "Setting measurement
thresholds" for other percentage threshold and absolute value threshold settings.
The following figure shows time measurement points.

Digital channel time measurements
Automatic time measurements Delay, Fall Time, Phase, Rise Time, X at Max, X at
Min, and are not valid for digital channels on the mixed-signal oscilloscope.
