7.9 Identifying Memory Space Required for Saving Arbitrary
Waveforms
The non-volatile memory can save arbitrary waveforms up to 128-waveforms or 4 Mi-words (8Mi
bytes).
The memory capacity (K-byte) required when saving an arbitrary waveform in the array format and
control point format, respectively is calculated by the following formula.
Array format: (2 x waveform length (word) + 768) / 1024 (rounding up the decimal point)
Control point format: (8 x the number of control 768) / 1024 (rounding up the decimal point)
The memory capacity required when saving an arbitrary waveform in the array format is shown in the
following table:
Waveform size

The example of memory capacity required when saving an arbitrary waveform in the control point
format is shown in the following table:

In the selection screen of the arbitrary waveform (common to both recall and save), the following items
are displayed in addition to the waveform number, [No.], and waveform name, [Name].
•
Data format [Type]: The waveforms in the array and control point formats are displayed as [RAW] and
[Point], respectively. The edit memory with No.0 is displayed as [Point] because of the control point
format.
•
Save memory capacity [Size]: For arbitrary waveforms between No.1 and 128, the memory capacity
used for saving is displayed in K-bytes. For the edit memory with No. 0, the memory capacity required
if it is saved is displayed in K-bytes.
•
Total save memory capacity [Total Size]: Total memory capacity currently used for saving arbitrary
waveforms between No.1 and 128 is displayed in K-bytes. The size of edit memory with No.0 is
excluded from the total capacity.
