TRIGger:SOURce INTernal: TRIGger:SOURce INTernal1-2 (E1563A) or TRIGger:SOURce:INTernal1-4 (E1564A) triggers a reading when the level specified by TRIG:LEVel <channel> is met. The TRIG:SLOPe setting determines whether the trigger occurs when the signal rises above (POSitive) or falls below (NEGative) the specified level on that channel.

CALCulate Disabled: If TRIGger:SOURce INT<n> is set, CALCulate<n> :LIMit:LOWer[:STATe] or CALCulate<n>:LIMit:UPPer[:STATe] are disabled if they were enabled, where <n> represents the channel number used for the internal trigger source and the channel used for testing a limit. See Chapter 2 for information about how the internal trigger source is driven by the level signal.

Master/Slave Operation: TRIG:SOURce1 is set to the appropriate TTLT<n> line by TRIG:MODE MASTer SLAVe. TRIG:SOURce1 cannot be changed unless the trigger mode is NORMal. Attempting to change TRIG:SOURce1 when mode is MASTer or SLAVe will cause a “settings conflict” error.

TRIG:SOURce2 is not affected by TRIG:MODE MASTer SLAVe operation.

Executable when initiated: No

Coupled command: Yes. TRIGger:LEVel, TRIGer:MODE, OUTPut:TTLT<n>:SOURce TRIG and CALC:LIMit:LOWer[:STATe] and CALC:LIMit:UPPer[:STATe]. Changes to TRIG:SOURce1 will cause a “settings conflict” error if TRIG:MODE is set to MASTer or SLAVe.

Reset (*RST) condition: TRIGger:SOURce1 IMMediate and

TRIGger:SOURce2 HOLD

TRIGger:SOURce[<n>]?

Parameters

Comments

TRIGger:SOURce[<n>]? queries present setting for the specified trigger source (1 or 2). The command defaults to trigger source number 1 if <n> is not designated.

Information Returned: This command returns one of the following responses

indicating the trigger source setting: BUS, EXT, HOLD, IMM, INT, INT2, INT3, INT4, TTLTn (where n = 0 to 7). Internal level trigger on channel 1 is returned as INT versus INT1 (the “1” is implied). The internal level trigger for channels 2, 3 and 4 return INT2, INT3 and INT4, respectively.
