9.4 Analyzing Data
242
Data recorded with the Real-Time Saving function can be subjected to numerical
value calculations, waveform calculations and FFT analysis. In all cases, load
the index file (.RSI) created by the Real-Time Saving function, display (load) the
measurement waveform area to be used for calculation, and select the desired
function.
Performing numerical value and waveform calculations
1. With the Real-Time Saving function selected, load the measurement wave-
form area to be used for calculation from the whole waveform.
2. Switch to the Memory function.
3. Make the required calculation settings with the Memory function, and execute
calculation.
See "Chapter 1 Numerical Calculation Functions", "Chapter 2 Waveform Calculation
Functions" in the Analysis Supplement
Performing FFT waveform analysis
1. With the Real-Time Saving function selected, load the measurement wave-
form area to be used for calculation from the whole waveform.
2. Switch to the FFT function.
3. Set the [Reference] (source) data input selection to [From Mem], Make the
required calculation settings, and execute FFT analysis.
See "3.4 Setting FFT Analysis Conditions" in the Analysis Supplement
9.4.2 Calculating
• When a calculation is executed, waveform data from the Real-Time Saving
function is cleared, and data can be displayed only with the Memory function.
• Waveform calculations cannot be performed if the loaded recording length is
greater than the maximum recording length allowed for calculation. Shorten
the [Load] length setting, reload the data, and try calculating again.
