Waveform Calculation Function
The instrument makes calculations using acquired waveform data and pre-defined arithmetic
expressions to numerically display calculation results on the waveform screen.
When the real-time save is set to [On] , you cannot use the waveform calculation function.

Operation available on the [Waveform calculation] screen
Waveform Calculation
• Four arithmetic operations (+, −, ×,
÷)
• Absolute value (ABS)
• Exponent (EXP)
• Common logarithm (LOG)
• Square root (SQR), cube root
(CBR)
• Moving average (MOV)
• Parallel move in the time axis
direction (SLI)
• Differential (1st-order [DIF], 2nd-
order [DIF2])
• Integration (1st-order [INT], 2nd-
order [INT2])
• Trigonometric function (SIN, COS,
TAN)
• Inverse trigonometric function
(ASIN, ACOS, ATAN, ATAN2)
• Waveform shifting by the PLC
delay time specified in Model
MR8990 Digital Voltmeter Unit
(PLCS)
(12 types in total)
Waveform parameter
• Average value (PAVE)
• Maximum value (PMAX)
• Minimum value (PMIN)
• Level (PLEVEL)
• Calculation by specifying a range
between cursors
You can specify a calculation
range between trace cursors A
and B or between trace cursors C
and D.

expressions
“8.3 Operators of Waveform
Calculation and Calculation Results”
(p. 169)
In addition to the four arithmetic operations, 11 functions are available to calculate waveform data. You
can specify up to 16 arithmetic expressions.
When the scaling function is enabled, the instrument makes calculations using scaled values.
