DURATION  Duration is the time it will take for the output voltage to 
reach the END VOLT level. As such, “Duration” will 
define the slew rate of the output voltage for the event. 
A duration of 0 seconds will cause the output voltage to 
reach the end voltage immediately. The DUR SCALE 
defines the time parameter CYCLES or SECONDS  
END DELAY  This is the time delay the voltage level will stay at END 
VOLT before it proceeds with the next transient event 
or completes the transient. 
FUNCTION  [3Pi controller only] This field can be used to select the 
wave shape to be used during this step of the transient 
sequence. Each step can use a different wave shape 
from the available library of 50 user-defined waveforms 
or the three standard waveforms. The output wave 
shape changes upon entry into each step and remains 
in effect for the duration of the step. The default wave 
shape is always the SINE (sine wave). 
REPEAT  This is the number of times the VOLTAGE SWEEP/STEP 
transient event will repeat before it proceeds to the 
next event or exit the transient program. Note that the 
number of times the transient event is generated is 
equal to the REPEAT + 1. Leave this value at zero if 
only one execution of this event in the list is required.  
EVENT #  This must be the last item in the transient edit screen. 
All data fields must be entered before inserting the 
EVENT #. The EVENT # takes a value from 1 to 99. The 
EVENT # defines the order of execution of the transient 
events in a multiple event transient. It is a good 
practice to enter spaced EVENT #’s to allow insertion of 
an EVENT later if needed. (For example, space them by 
5.) Entry of a sequence EVENT # number will cause the 
display to return to the TRANSIENT screen.
