AWG2021 User Manual
In Waveform Advance mode not only sequence files, but also waveform files
can be used. In this case when the trigger is received, the file’s waveform is
output continuously.
When the sub sequences in a sequence file are output, they are expanded
individually in the waveform memory. In Waveform Advance mode, they may
not operate as intended. To avoid this, the function (Expand SEQ into WFM
item on the initial EDIT menu) is used to expand the sequence file into a
waveform file. See page 3 -12. Expanding a sub sequence into a waveform file
and registering it into the sequence file makes Waveform Advance mode easier
to use.
Use Autostep mode to start an Autostep file created with the EDIT menu
Autostep editor. An Autostep file stores a program that specifies a waveform or
sequence file (including output parameters) for each channel for each step.
Autostep mode resembles Waveform Advance mode in that each time a trigger
is received, the display advances one waveform. However, in this mode the
output parameters for each waveform change as well. The operating mode for
each step is triggered. The waveform or sequence for the step is output once,
then output stops. Just as in other operating modes, the Autostep mode trigger
signal can be generated from the external trigger signal or by pressing the front
panel MANUAL button.
NOTE. During Autostep mode, changes to the output parameters with the
SETUP menu have no effect.
When Autostep is selected, the following items will be displayed in the side
menu:
Slop
Level
Impedance
Select Autostep File
STOP
The Slope, Level and Impedance items are used to set the trigger conditions for
the external trigger signal.
During waveform output, if STOP is selected from the side menu, the waveform
output is stopped immediately and the system returns to the start of the Step:1
waveform or sequence.
When a trigger signal is received, the Step:1 waveform for each channel is
output once; when the next trigger signal is received, the Step:2 waveform is
output (once). When the next trigger signal is received while waveform output is
