Tektronix MSO64 [387/628] Add functions math equation editor

Add Variable menu fields and controls.

Field or control Description

Variable Type Selects a predefined variable to add to the Variables column of the Equation Editor.

Sample Rate creates a variable with the value of the current sample rate.

Sample Interval creates a variable with the value of the current sample interval (1/sample rate)

Record Length creates a variable with the value of the current record length.

Cancel Closes the menu without adding a variable to the Equation Editor Variables column.

OK Closes the menu and adds the current variable selection to the Variables column of the

Equation Editor's Sources table.

Add Functions (math Equation Editor)

Use the Add Functions controls to add predefined math operations to your math waveform equation.

Button Description

Integral. Inserts the text INTG( into the math expression. Enter an argument to the function. The integral

function produces the integral of the argument.

Inserts the text MAX( into the math expression. The MAX function accumulates, over time, the maximum

value at each point in the vector.

Base 10 logarithm. Inserts the text LOG( into the math expression. Enter an argument to the function. The

log function produces the base 10 logarithm of the argument.

Natural antilog. Inserts the text EXP( into the math expression. The EXP function produces the natural

antilog of the argument.

Ceiling function. Inserts the text CEIL( into the math expression. CEIL returns the smallest integer that is ≥

the expression within the parenthesis.

Inserts the text INV( into the math expression. Enter an argument or channel to the function. The invert

function inverts the argument within the parentheses.

FFT Magnitude. Inserts the text FftMag( into the math expression. Select one of the waveforms as an

argument to the function. This function creates an FFT waveform that shows the magnitude components of

the source signal.

FFT Phase. Inserts the text FftPhase( into the math expression. Select one of the waveforms as an

argument to the function. This function creates an FFT math waveform that shows the phase components

of the source signal.
