Page 233 11.1 Sequence Oscillation Example After that, when stop operation is performed, the sequence moves to Step 0. Since [StepTerm] is set to [End], the sequence moves to Step 0 even if resume operation is performed. Note that if the [StepTerm] is set to [Continue], the sequence moves to Step 4 when resume operation is performed.
Page 234: Basics
11.2 Basics 11.2 Basics This section describes the necessary information you should know when using the sequence oscillation. a) Difference between sequence oscillation and normal oscillation During sequence oscillation, the unit operates on individual waveform, frequency, and amplitude settings, which are independent from normal oscillation (continuous, modulated, sweep, and burst). In another word, the sequence oscillation and the normal oscillation operate as a separate oscillator independent from each other.
Page 235 11.2 Basics 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. •...
Page 236 11.2 Basics e) Phase at step end [StopPhs] Normally, when the prescribed step time has elapsed, the sequence moves on to the next step regardless of the reference phase. However, if you wish to set the sequence to move on to the next step after the completion of one cycle of waveform, it is possible to specify the end phase (stop phase).

Page 238 11.2 Basics f) Phase at step start If the waveform of the previous step is DC or noise, oscillation in the next step starts from reference phase 0°. Phase 0° here is the phase value based on the reference phase as in the case of the phase at step end (stop phase). The start phase that appears in the actual output is the phase setting value of that step.
Page 239 11.2 Basics h) Two types of branches The control flow can be changed by the panel operation or by the external signals. This is called branching. For example, branching can be used to set the sequence to move to a different step in response to a status change of the equipment under test.
Page 240 11.2 Basics j) Limitation of available waveform The waveforms that can be used for sequence oscillation are limited to sine wave, square wave (both standard and extended duty variable range), noise, DC, and arbitrary waveform. When you wish to use a ramp wave or parameter-variable waveform, copy the desired waveform to the arbitrary waveform and save it as an arbitrary waveform in advance in the ARB Edit screen.
Page 241 11.2 Basics l) Channel coordination (WF1968 only) The step control parameters are common to both channels. The sequence makes the same step transition for both channels. However, since the stop phase can be controlled only by the channel 1 side, the stop phase of channel 2 does not necessarily match the desired value. On the other hand, the intra-step channel parameters can be set independently for each channel.
