When selecting this trigger source, the field below the TRIG

SOURCE field changed to "TRIG PHASE =". Use this field to

enter the desired voltage phase angle to trigger the

measurement on.

This mode is appropriate when capturing analyzing events at a

specific phase angle such as the zero crossing of the voltag

Note that the phase angle of the current with respect to the

voltage is determined by the load, so triggering at a specific

phase current angle is not possible as it is not controlled by t

AC source. However, when capturing current waveform data

the phase relationship to the voltage can be determined easily

by triggering at the 0° point on the voltage.

This mode performs two functions. It programs the output

voltage for the selected phase or phases to the rms or DC va

specified and it triggers the measurement acquisition at the

same moment in time.

When selecting this trigger source, the field below the TRIG

SOURCE field changed to "SET VOLT =". Use this field to enter

the desired voltage to program the output to and trigger the

measurement on. If only one phase in a thre

selected, only that phase's output will be program

phases are selected, all three phases' outputs w

programmed. Use the PHASE key to select the desired p

or all phases. Figure 4-39 sh
