Keysight B2900 User’s Guide, Edition 5 6-29Function DetailsTrigger SystemTrigger SourceB2900 supports the following trigger sources. The trigger source must be set to theARM event and the TRIGGER event individually.• AUTO (automatic internal, AINT): Trigger source best suited for the presentoperating mode is automatically selected by the internal algorithms.• BUS: Remote interface trigger command such as GET, TRIGger, and *TRG• TIMER (timer, TIMer): Signal internally generated every interval set by thePeriod field• INT1 or INT2 (internal): Signal from the internal bus 1 or 2• EXT1, EXT2, EXT3, EXT4, EXT5, EXT6, EXT7, EXT8, EXT9, EXT10,EXT11, EXT12, EXT13, or EXT14 (external): Signal from the DIO pin n,which is an I/O port of the Digital I/O D-sub connector on the rear panel. n=1 to14• LAN: LXI triggerDevice ActionsB2900 supports the following device actions. Also see Figure 6-9.• Transient device action (source output)Source channel starts source output for applying one output value if theTRIGGER event was detected and the Source delay time elapsed.• Acquire device action (measurement)Measurement channel starts measurement for obtaining one measurement data ifthe TRIGGER event was detected and the Measure delay time elapsed.NOTE To synchronize the channel operation, for the 2-channel modelsIf channels are set as shown below, the device actions start simultaneously.• To synchronize source output:• Trigger source is set to the same mode.• Delay time is set to the same value.• Source output ranging mode is set to the fixed mode.• Source wait time control is set to OFF.
