Arbitrary (ARB) Waveform File Headers
WFM1
This choice will display all of the waveform segments that currently reside in
volatile memory.
3. Press the
NVWFM
softkey.
After pressing the softkey, you are returned to the waveform file listing table that now displays the
waveform files from non-volatile memory. This is shown in
Figure 4-9 .

4. Highlight a waveform file.
5. Press the
View Header
softkey.
The file header for the selected waveform file is shown in the ESG display. If there was a waveform playing,
its header information is removed from the ESG display, but its settings are still used by the signal generator.
There are two ways to return to the header information for the playing waveform. One way is to press the
View Different Header
, select the current playing waveform file, and press
View Header
. The second way is to
press
Return
and then

Playing a Waveform File containing a Header
After a waveform file (
AUTOGEN_WAVEFORM
) has been generated by a modulation format and the format is
turned off, the
AUTOGEN_WAVEFORM
file is accessible to and can be played back only in the dual ARB
player. This is also true for downloaded waveform files.
The file header settings, associated with the waveform file, are used to configure signal generator settings
and parameters when the waveform is selected for playback in the dual ARB. Some of these settings will
appear as part of the softkey labels. In addition, some of the saved header settings will appear on the dual
ARB summary display. This is shown in
Figure 4-10 on page 105 . Follow the procedure “Playing a
Waveform Sequence” on page 109 to apply file header settings and to play back a waveform.
