4.2.7 WAVEFORMS Menu [ iX Series only ]
Figure 4-17: WAVEFORMS menu
The WAVEFORMS menu is available on the iX Series only. If your unit is an i Series, pressing
the WAVE key on the front panel function keypad has no effect. The WAVEFORMS menu allows
selection of the waveshape for each phase individually or all phases at once. For three phase
versions of the iX Series, the mode is determined by the phase coupling. If only a single phase is
selected in the top right corner of the display (øA, øB or øC), the selected waveshape will be
applied to that phase. If all phases are selected (phase coupling), the selected waveform will
apply to all three phases.
For single phase versions of the iX Series, the phase coupling is always set to phase A, so
pressing the PHASE button has no effect.
The following fields are available in the WAVEFORMS menu:
CLIP LEVEL This parameter determines the amount of total harmonic
distortion of the built-in CLIPPED sinewave waveform. The
range is 0 % through 20 % THD.
Note that changing the distortion level of the CLIPPED sinewave
while the CLIPPED sinewave is used on the output of one or
more phases, forces the output of the AC Source to be dropped
momentarily. To avoid this, make sure none of the phases is
using the CLIPPED sinewave function when changing the clip
level.
GROUP The group field displays the currently selected waveform group.
The iX Series provides four groups of 50 user defined
waveforms each for a total of 200 waveforms. Only one group
can be active at a time however. This field only displays the
selected waveform group. It cannot be used to change the
actual group selected. Group selection must occur at power up
and is done from the INITIAL SETUP 3 screen. See section
4.2.11.3 for details.
MODE The mode field determines the operation mode of the
WAVEFORMS display screen. Available options for this field
are:
PROG: This mode is used to change the programmed
waveshape function on the selected phase. This is also the
default mode of operation.
VIEW(T): This mode can be used to display any of the
available user defined waveforms in a time domain display.
Previewing a waveform can be useful if you are unsure about
the nature of the waveform that was stored.
