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, or between A/B cursors
Calculation types Average, RMS or P-P values, maximum, minimum and time to max/min values, 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 calcu-
lation, phase contrast calculation, High level calculation, Low level calculation
Print calculation results Included
Auto-save calculation results After measuring, automatically saves to CF card or hard disk (text format)
Judgment of calculation results GO, NG, GO&NG stop according to max/min value of calculation result
Judgment output GO, NG signal at open-collector output from external control terminal (5 V, active LOW), Pulse
width: at least 1.8 ms
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 1/4 maximum memory capacity
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
Printing of calculation results Included
Automatic saving of calcula-
tion results After measurement, automatic saving to CF card or HDD (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)
When block display is ON: 40 ms or more (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
Automatic saving of calcula-
tion results After measurement, automatic batch saving to CF card or HDD (binary, .txt file)
