Users Manual
The waveform offset can be changed on a section of the waveform defined by the
start and stop addresses. Set the addresses by pressing the appropriate soft-key
and making entries directly from the keyboard or by using the rotary control.
The data values over the specified section of the waveform are offset by the value entered
in the WAVE OFFSET field. Press the appropriate soft-key and make entries directly
from the keyboard or by using the rotary control. Entries in the range -4096 to +4095 will
be accepted; this permits, in the extreme, waveform sections with values at the -2048
limit to be offset to the opposite limit of +2047. Warnings are given when the offset
causes clipping, although the entry is still accepted. The original waveform can be
restored by pressing the undo soft-key.
Offset edit operates on the version of the waveform in the channel currently selected by
the channel SETUP keys; the effect of the edit can be seen by selecting the waveform to
run on that channel. When the offset has been modified as required the new waveform
can be saved by pressing the save
waveform in the backup memory and also any other copies of the waveform in other
channel memories. After the edited waveform has been saved the original waveform
cannot be recovered.
Pressing the exit soft key returns to the
saving any changes.

Wave Invert

Pressing the wave invert soft-key calls the INVERT screen:
The inversion can be applied to a section of the waveform defined by the start and
stop addresses. Set the addresses by pressing the appropriate soft-key and making
entries directly from the keyboard or by using the rotary control.
The data values over the specified section of the waveform are inverted about 0000 each
time the invert soft-key is pressed.
Press exit to return to the EDIT FUNCTIONS screen.
