INPut:DIP:TRIGger
This command triggers all dip/swell phenomena that have external trigger selected. It has
the same effect as supplying a trigger signal to the rear input External Trigger BNC.

5-52. General Commands
[SOURce]:FREQuency(?) <dnpd>
This command is used to set the fundamental frequency for all voltage and current channels
on all phases. The <dnpd> is a number, which sets the required fundamental frequency,
expressed in Hz. It will automatically choose the best hardware range for the defined
frequency of output.
The query version will return the present output frequency value. The returned number will
be in standard scientific format (300 Hz would be returned as 3.0E2).
[SOURce]:FREQuency:LINE(?) <bool>{OFF|ON|0|1}
This command is used to set the line locking of the frequency for all voltage and current
channels on all phases.
• ON or 1 will select line locking.
• OFF or 0 will select line locking
The query command will return 1 if line locking is enabled, or 0 if line locking is disabled.
[SOURce]:FREQuency:LOCK?
This query only command returns line lock state:
• 1 indicates that line-lock has been achieved.
• 0 indicates that line lock has not been achieved.
[SOURce]:POWer:UNBalanced?
This query only command returns the current three-phase unbalanced percentage value. It is
calculated using either the IEC or NEMA methods. Note that if the system is not configured
as a three-phase system, then this this query returns a value of zero.
[SOURce]:POWer:UNBalanced:STANdard(?) <CPD>{ NEMA | IEC }
This command selects the method for calculating the three-phase unbalanced value.
[SOURce]:POWer:BUDeanu? <cpd>{DELTa|WYE}[, <cpd> { P | S | Q | D |PF}]
This command is a query only. It returns the Budeanu power values for a three phase system
calculated for the system connected in a delta or Wye (star) configuration.
If the optional second <cpd> parameter is not present, then all values in comma separated
format, in the order P, S, Q, D, PF will be returned. If the second <cpd> parameter is
present, then just that value will be returned. The returned numbers will be in standard
scientific format.
[SOURce]:FLICker:STANdard(?) <cpd>{ STD1 | STD2 }
Flicker can be produced to two different standards and this command selects which one is
used:
STD1 IEC 61000-4-15 (2003-2) Ed 1.1.
STD2 IEC 61000-4-15. Ed 2.0
[SOURce]:TERMinal[:STATe](?) <bool>{OFF|ON|0|1}
