DESCRIPTION
using the PHASE key first.
Sets the clip level for the CLIPPED sine wave in percent VTHD.
The range is 0 to 20 %. (iX models only).
Note: Changing the clip level setting will result in temporary loss
of the output voltage as the new clipped waveform is loaded.
This may cause the EUT to reset or turn off. To avoid this, set
the desired clip level before programming the AC voltage and
turning on the output to the EUT or use the transient list system
to switch between waveforms.
Selects the available output modes of operation. Available
modes are AC, DC (i/iX models) and ACDC (iX models only).
The shuttle can be used to select the desired output mode.
This parameter applies only when the power source is in ACDC
mode. The DC o
ffset can only be set in percent of the AC RMS
voltage programmed. (Relative programming only). The
available dc offset range is ±20%.
NOTE: Offset programming is phase specific. To program all
three output phases at the same time, use the PHASE key first
to select coupled mode (A, B, C phase indicator all on). To
program an individual phase only, select the desired phase
using the PHASE key first.
Note: Changing the offset percentage setting will result in
temporary loss of the output voltage as the new offset is
recalculated and loaded. This may cause the EUT to reset or
turn off. To avoid this, s
programming the AC voltage and turning on the output to the
EUT.
Sets the current limit value for the current detection system.
When the load current value exceeds the set current limit, a fault
condition is generated. The actual response of the AC Source to
a current limit fault is determined by the
selected in the OL MODE field. (CC = Constant Current, CV
Constant Voltage).

trip off and stay off until re-engaged. In CC mode, the voltage
will be reduced until the current limit is no longer exceeded.
