Arbitrary Waveform Generation
Modifying Arbitrary Waveforms 9
Block copy edit operates on the version of the waveform in the channel currently selected
by the channel SETUP keys, and the effect of the edit can be seen by selecting the
waveform to run on that channel.
When your waveform is ready it can be saved by pressing the save soft-key; the action
of saving modifies the 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 EDIT FUNCTIONS screen without saving
any changes.
Waveform Amplitude
Pressing the wave amplitude soft-key calls the AMPLITUDE screen:
AMPLITUDE: 0
01.00
start: 00400
stop: 01000 undo
exit save
The waveform amplitude 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 rotary control.
The data values over the specified section of the waveform can be multiplied by a factor
of between 0·01 and 100·0 by making entries in the AMPLITUDE field. Press the
appropriate soft-key and make entries directly from the keyboard or by using the rotary
control. The amplitude changes on completion of the entry. Note that entries greater
than 1·0 will cause clipping if the waveform already uses the full -2048 to +2047 data
value range; the result is, however, still treated as a valid waveform. The original
waveform can be restored by pressing the undo soft-key.
Amplitude 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 amplitude has been modified as required the new
waveform can be saved by pressing the save soft key; the action of saving modifies
the 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 EDIT FUNCTIONS screen without
saving any changes.
Waveform Offset
Pressing the wave offset soft-key calls the WAVE OFFSET screen.
WAVE OFFSET: +0
000
start: 00400
stop: 01000 undo
exit save
