ENTRY DESCRIPTION
cannot be changed.
PHASE Selects the phase angle between the external clock and the
output of the AC source. If the clock source is internal, this
parameter has no effect.
FUNC Selects the waveform for the selected phase. Available choices
are SINE, SQUARE and CLIPPED or any user defined waveform
that was downloaded to the AC source waveform memory using
the IEEE-488 or RS232C interface.
CLIP LEVEL Sets the clip level for the CLIPPED sine wave in percent VTHD.
The range is 0 to 20 %.
CURR 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 protection mode
selected in the OL MODE field. (CC = Constant Current, CV =
Constant Voltage).
OL MODE Sets the current limit over load mode. The actual response of the
AC Source to a current limit fault is determined by this setting.
Available settings are CC for Constant Current mode or CV for
Constant Voltage mode. In CV mode, the AC source output will
trip off and stay off until re-engaged. In CC mode, the voltage will
be reduced to maintain the set current level.

Figure 4-5: CONTROL Menus
The CONTROL menu is shown in Figure 4-5 and can be reached by selecting the Menu key,
selecting the CONTROL entry using the DOWN cursor key and then pressing the Enter key.
The CONTROL menu is used to change secondary output parameters. The following choices are
available in the CONTROL menus:
ENTRY DESCRIPTION
SENSE Selects internal or external remote sense mode. If INT is selected,
the voltage is sensed at the output terminal block. If EXT is selected,
the voltage is sensed at the external sense connector. If external
sense is selected, care must be taken to connect the external sense
lines at the load. For sense leads longer than 1 meter, twisted pairs
