Figure 5-12: VOLTAGE SWEEP/STEP SETUP Screen
The Voltage sweep and step screen shown in Figure 5-12 can be reached from the transient screen as
follows:
1.
Scroll to the VOLT SWEEP/STEP entry using the up and down keys.
2.
Press the ENTER key to bring up the VOLTAGE SWEEP/STEP screen.
The VOLTAGE SWEEP/STEP screen has several data fields. All data fields that are blank to the right of
the equal sign must be filled or an error message will occur when trying to leave this screen. The EVENT
# is the last data field to be filled. Entering the event data field will cause the display to return to the
TRANSIENT screen where a new selection can be made.
The VOLTAGE SWEEP/STEP screen has the following fields:
START
This field will show the start phase angle of the voltage transient in
degrees. Only one start phase angle per transient sequence is allowed.
The start phase angle must be in the first transient event in the list. The
start phase angle is not valid for DC transient.
END VOLT
This is the output voltage level at the end of the transient event in
volts.
DUR SCALE
Duration scale default is time in seconds. Use the Shuttle knob to
select CYCLES if desired. Note that durations expressed in cycles
may cause rounding errors if the period of the selected frequency
setting is not an integer number of mss. Thus, for 50 Hz applications,
no rounding errors occur but for 60 Hz, the 16.66
¯ ms period will
cause a rounding error when converted. The Duration scale selection
affects both the DURATION and END DELAY parameters.
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
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 will proceed to the next event or exit the
transient program. Note that the number of times the transient event is
generated is equal to the 1. Leave this value at zero if only
one execution of this event in the list is required.
