10.2 Settings for Numerical Value Calculation
Procedure
To open the screen: Press the STATUS key → [Num Calc] sheet
1
Enable the Numerical Calculation function.
Move the cursor to the [Numerical Calc] item.
Select [On].
2
Specify the Numerical Calculation range.
Move the cursor to the [Calc Area] item.
See: "7.2 Specifying a Waveform Range (A/B Cursor)" ( p.105)

Perform calculation settings.
(1)
Select the calculation type.
Move the cursor to the number of the calculation type for
which to make settings, and select the calculation type.
(When you select [List] a list of calculation types appears. To clear the dis-
play, press the TRIG.SET key once more.)
WholeWave Applies calculations to the whole
waveform. (default setting)
A-B Wave Applies calculations to the data be-
tween A/B cursors.
.Calculation No.

Phenomenon
*: Setting can also be made for logic channels
X-Y Area Area of X-Y composite waveform
Time to Lev* Time from trigger to specified level
Lev-time Measurement value at a specified time
point after triggering
Pulse Width* Pulse width of waveform data
Duty Ratio* Duty of waveform data
Pulses* Pulse count of waveform data
Calculation Four arithmetic operations on numerical
calculation results
Time Diff* Time difference between phenomenon A
and B.
Phase Diff* Time difference between phenomenon A
and B displayed as a phase contrast.
High Level High level value for waveform data
Low Level Low level value for waveform data
Off No calculation. (default setting)
Average Average value of waveform data
Rms RMS value of waveform data
Peak-Peak Peak-to-peak value of waveform data
Maximum Maximum value of waveform data
Max-Time Time from trigger to maximum value
Minimum Minimum value of waveform data
Min-Time Time from trigger to minimum value
Period Period of signal waveform
Frequency Frequency of signal waveform
RiseTime Rise time of waveform data
FallTime Fall time of waveform data
Std Dev Standard deviation of waveform data
Area Area enclosed by zero position and
signal waveform
When selecting [A-B Wave], specify the
calculation range using the A/B cursors on
the Waveform screen.
If no measurement data has been ac-
quired by the instrument, first measure
once so that the range can be specified for
calculations to be applied to subsequent
measurements.
Also select [Judge] if you require judg-
ment of calculation results.(
