Computation functions (MEM
)
Waveform processing calculations*
1
Arithmetic operations, absolute value, exponents, common logarithms,
square roots, moving average, 1st and 2nd derivatives, 1st and 2nd
integrals, parallel displacement on time axis, trigonometric functions,
reverse trigonometric functions
16 arbitrary operational equations: Calculations are possible up to a
recording length that corresponds to one fourth of the memory
capacity.
Waveform parameter calculations*
1
Average value, RMS value, peak-to-peak value, maximum value, time
to maximum value, minimum value, time to minimum value, period,
frequency, rise time, fall time, area value, XY area value, standard
deviation（parameter calculation result can be saved on floppy disk,
MO disk, and so on.)
Averaging function
Additive averaging, exponential averaging (2, 4, 8 to 256 samples)*
1
Simple average, exponential average , peakhold (2, 4, 8 to 4096
samples) *
2
Memory segmentation ・Memory can be segmented among channels.
・Number of segments: Maximum 255
・Batch saving of all blocks can be selected.
Sequential saving*
1
*
3
・Input signal capture is carried out continuously using the trigger,
storing waveform data successively in each block.
・Displaying waveform ON or OFF can be selected.
Multi-block*
1
・Recording the waveform data in an arbitrary block.
・Displaying arbitrary blocks in duplicate.

2
Waveform area evaluation *
1
*
2
・Waveform evaluation based on evaluation area for Y-T waveform, X-Y
waveform, or FFT results
・Evaluation modes
・Out: fail if any part of waveform is outside evaluation area
・All out: fail if whole of waveform is outside evaluation area
・Stop modes
・GO (pass) stop, NG (fail) stop, GO & NG stop
・Printer output or waveform save at stop
・Decision time：Approx. 20 ms max
・Evaluation cycle：Approx. 250 ms*
