17.5 Built-In Functions
Calculation functions Memory Function supported
Number of calculations Up to 16 calculations can be applied to any channel
Calculation range Whole range, between A/B cursors or after trigger
Calculation types Average, RMS value, P-P value, maximum value, time to maximum value, minimum value,
time to minimum value, period, frequency, rise time, fall time, standard deviation, squared value,
X-Y squared value, time to level, level at time, pulse width, duty ratio, pulse count,
four basic arithmetic operations, time difference, phase difference, High level, Low level
Auto-save calculation results After measuring, automatically saves to USB memory stick (text format)
Statistical calculation First, average, maximum, or minimum
Judgment of calculation re-
sults Calculation results can be judged based on the specified maximum/minimum value
Stop condition: GO, NG, GO&NG
Evaluation output Outputs GO or NG judgment signal via external control terminals
Open collector output
With 5 V voltage output, active low, Low output level 0 V to 0.5 V (current of 15 mA)
Pulse width: 1.8 ms or more
Calculation support function Memory Function
Number of calculations Up to a maximum of 16 calculations for desired channels
Calculation range All range, between A/B cursor selections
Calculation record length Up to 2,000 div
Operators Four arithmetic operations, absolute vales, indexes, common logarithms, square root, moving av-
erage, differential (primary, secondary)
Integral (primary, secondary), parallel displacement of time axis direction, trigonometric function,
reverse trigonometric function, integration time correction based on NPLC setting
Automatic saving of calcula-
tion results After measurement, automatic saving to USB memory stick (binary, .txt file)
Division support function Memory Function
Number of memory divisions 2 to 1024
Divided record length Can be set as desired (but depends on the number of divisions)
Sequential saving Possible by specifying start and end blocks
Sequential saving dead time When block display is OFF:
1 to 8 samples (time axis 5 ms/div to 20 ms/div)
1 sample (time axis 50 ms/div or more)
Multi-block saving Saving of waveforms is possible by specifying the desired blocks of divisions
Block display Display can be set to ON or OFF
Block overlaying Desired blocks or all blocks
Cursor suooerting Functions Memory function, recorder function, FFT function
Number of cursors Two (Cursors A and B)
Cursor types Line (vertical or horizontal) and Trace
Cursor movements A Cursor, B Cursor, A&B Cursors
Measurement function A Cursor : Amplitude at each cursor, time from trigger event
AB Cursor: Time, amplitude and frequency (period) differences between cursors
Cursor-supported channels All channels (default), or any specified channel
Included functions Partial saving (specified time span)
