3.5 Switching Output range

3.6 Waveform Selection

3.7 Sweep function

Operating steps
IT7600 series AC source will allow switchover between High range Low range
and Auto range.
User can choose the range according to actual test requirements, when High
range is selected, voltage setting value is under high level. When Low range is
selected, voltage setting value is under low level (refer to 9.1 Main technical
parameters for more details).If the auto range is selected, the instrument will
automatically switch to high level or low level, thus sparing complicated
operations such as manual setting.
NOTE
There is a temporary OFF to the AC source during the switchover of range.
The user can set the output waveform in the main interface of IT7600 series
power supply. Five output waveforms below are available:

Sine

Square

Sawtooth

Triangle

THDWave
When THDWave is selected, the user should configure the distortion waveform.
(refer to 8.4THD Wave for more details)
The Sweep function is used to test efficiency of switching power supply and
capture the voltage and frequency at the maximum power point. The voltage
and frequency of power may be altered in the form of step ladder by setting the
initial voltage, final voltage, step voltage, initial frequency, final frequency, step
frequency and one-step time. As the test closes, voltage and frequency at the
maximum power point may be displayed. Sweep function is not applicable
under DC mode and ACDC mode.
1. Press [Shift]+[List] (Step) on the front panel to enter the sweep interface,
as shown in the figure below.
