c) Intra-step parameter change pattern
Intra-change parameters, except for the waveform, have the following three patterns of value
changes within the step. These are called action settings. In case of waveform parameters, there is
no action setting. Instead, the setting is always done in that step.
• Constant [Const]
The value is fixed to that setting specified in the step.
• Keep [Keep]
The value immediately before the move to that step is maintained. This means, the value changes
according to the status of the previous step.
When the action setting is set to [Keep], you will not be able to perform a set of parameter values.
• Sweep [Sweep]
The value changes linearly over the step time from the value immediately before the move to that
step to the value set in that step. This means, after the lapse of the step time in that step, the value
reaches the set value. The starting value changes according to the status of the previous step.
d) Phase at sequence mode
In the sequence oscillation, the reference phase is generated internally, the value set in the reference
phase in the phase [Phase] will be output are added. Reference phase, frequency / amplitude / offset
/ phase changes in a continuous even if the change. Also, except for DC and noise, even if the
waveform changes and changes continuously. Immediately after output DC and noise will be the
reference phase resumes from 0 degree.
