4.4 Arbitrary Waveform
4-64 WF1946B
Other operations:
• Arbitrary waveform data input:
ARB EDIT
→ EDIT select →
ENTER
→ flashes the
waveform data (DT) digits. Use the keypad or
MODIFY
dial to set the data.
Data upper and lower limits are +32767 and −32768, which correspond to the amplitude peak-to-peak
settings. For this reason, when the waveform vertical limits are changed by the above type of
method, the amplitude setting (Vp-p) and the actual output waveform Vp-p do not coincide. The
data set addresses are automatically the linear interpolation addresses (the * mark is displayed).
• Clear (to 0) waveform data:
ARB EDIT
→ CLEAR select →
ENTER
, then again
press
ENTER
. The interpolation marks (*) are
also cleared.
• Apply a name to an arbitrary waveform:
ARB EDIT
→ NAME select →
ENTER
, then use the
MODIFY
dial to select the characters. Shift
position with

Up to 8 characters can be input. Following are
the usable characters.

The output waveform changes as described below when the waveform data size is changed.
If, for example, the waveform data size is changed from 16 KB to 8 KB when there is a waveform like
for waveform number 0, is assigned to waveform number 0 and to waveform
number 1.
• Arbitrary waveform data are common for CH1 and CH2.
