4 The Upset Event feature in the AC Module is implemented by switching to a different in-phase
AC RMS voltage value during the time specified by the duration parameter. The upset event is
generated by “pasting” a segment of the in-phase Volt1 waveform, starting at the parameter
Phase position, for parameter Duration length, in place of the presently output waveform. The
DC protection Fault protections are disabled during the generation of an Upset event, to prevent
system shutdown.
The Master/standalone module will at the start of the event, issue a 1 ms TTL positive trigger signal on
Pin 2, referenced to return on Pin 7, of the DB-9 Interface connector. The rising edge of the trigger
signal is output when the Phase parameter delay expires. The trigger signal has no programmable
options. The execution of the command for a stand-alone or Group Master is immediate.
The Phase Reference time marker is a timing signal that is generated by a Master or stand-alone AC
module. It is used by a module to mark when to apply their own phase offsets to set the timing of their
individual rising zero cross of the output voltage waveform. Zero cross and UPSET event timing are
referenced to the same time marker, but are independent of each other.
The SOUR:VOLT:UPSET Phase,Volt1,Duration,Volt2 command allows the Module to output a
transient voltage upset event; such as surges, sags, dropouts, brownouts, and spikes.
Phase: The Phase specifies the delay from the Phase Reference time marker to start the upset event. A
value of 0.0 to 3600.0 degrees is accepted, this allows the upset event to be skewed across multiple
cycles in a Phase group, if needed.
Volt1: The RMS voltage that will be output during the upset event.
