MODE Menu

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.

Autostep Mode 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
