TRIGger:SLOPe[<n>]?

TRIGger:SLOPe[<n>]? queries the present setting for the slope of the trigger signal for the trigger source (1 or 2) specified. Trigger slope for source number 1 is returned if <n> is not designated. Trigger slope applies only for TRIG:LEVel when the trigger source is INTernal or EXTernal. The command returns “POS” or “NEG”.

Parameters

TRIGger:SOURce[<n>] BUS EXTernal HOLD IMMediate INTernal1-4

TTLT0-7sets the source of the trigger for all channels or can disable the trigger source. The command defaults to trigger source number 1 if <n> is not designated.

Two trigger sources are allowed, TRIG:SOUR1 and TRIG:SOUR2, which are common to ALL channels on the E1563A and E1564A. SOUR1 is not associated only with channel 1 and SOUR2 is not associated only with channel 2.

Must Use INITiate: TRIGger:SOURce only selects the trigger source. You must use INITiate to place the digitizer in the wait-for-trigger state.

TRIGger:SOURce EXT: TRIGger:SOURce EXT uses the External Trigger In Port “Trig” pin (on the D sub-miniature connector) as the trigger source. The digitizer triggers on the falling (negative-going) edge of a ± 5V TTL input signal (maximum input is +5V peak to the “Trig” pin).

TRIGger:IMMediate: TRIGger:IMMediate causes a trigger to occur immediately provided the digitizer is placed in the wait-for-trigger state using the INITiate command.

Using GET or *TRG: When a Group Execute Trigger (GET) bus command or *TRG common command is executed and the digitizer is not in the wait-for-trigger state, the “Trigger ignored” error is generated.
