Measurement triggering
Figure 4-2 shows the general sequence for measurement triggering. The basic
sequence is as follows:
• When the output is turned on, the programmed source value is immediately
applied to the DUT.
• For front panel operation, if the immediate trigger source is selected, a
measurement will be triggered immediately. However, if the manual trigger
source is selected, the front panel TRIG key must be pressed.
• For remote operation, the unit waits the programmed timeout period for a
GET (GPIB only) or *TRG (both interfaces) trigger command.
• The unit waits for the programmed delay period (if any).
• The instrument takes one measurement.
• If the number of measurements is less than the programmed trigger count,
the unit cycles back to take another measurement (the measurement cycle
will be repeated indefinitely if the infinite trigger count is selected).
• For multiple measurements, the unit waits for the programmed trigger
interval (if any) before taking the next measurement.
