Configuration Arbitrary Waveform

Number of cycles to generate surge/sag waves. This
parameter is meaningful only in Peroid mode.
This setting is used in combination with Repeat count, for
example, if Repeat count is set to 5 and Period count is
set to 10, five surge/sag waves occur in every 10 cycles.
Phase A/Phase B/Phase A&B/Phase B&C/Phase
A&C/PhaseA&B&C:
Select the phase information where the surge/notch
occurs.(displays under 3-phase mode)
Synchronize: Each of the three phases executes
surge/trap at the same time.
Specify Phase: Each of the three phases executes
surge/trap at the specified phase.
(displays under 3-phase mode)
Value select:
Percent: Set the percentage of the surge/trap amplitude to
AC signal amplitude (RMS).
Setting: Set the value of the surge/trap amplitude.
1. Press [On/Off] on the front panel and enable the input.
2. Press [Run] on the interface, Then the running status will be displayed on
LCD. Input parameters and measurement parameters are displayed on the
left side of the interface. You can also press the Meter to observe the input
parameters in the main interface.
3. After execute, [On/Off] on the front panel will be off, and running status will
be displayed on LCD. You can press [Stop] on the interface to stop the
surge/sag function.
8.3 Self-defined Waveform Function
In AC mode, you can customize waveform curves and save them locally as input
waveform options. This self-defined waveform can be used as a normal input
waveform or as a wave option for scanning waveform, Surge/Sag waveform,
and LIST waveform.
8.3.1 THD
The distorted waveform can simulate current harmonic wave in the circuit. The
user can set the extent to which the input current waveform deviates from the
Sine wave voltage and test the usage of the DUT under this circumstance.
THD includes built-in 30 waveforms and user-defined waveforms.The interface
is shown below.
