:MODE <name>
This command selects basic triggering.
Usage
:SYSTem:MACRo:TRIGger[:EXECute] <name>
<name>
CONTinuous
: Continuous trigger mode
ONEShot
: One-shot trigger mode
Details
This command specifies the basic trigger mode. With
CONTinuous
triggering selected, the Model
6517B continuously triggers readings after the selected source event occurs. With
ONEShot
triggering selected, a single reading is triggered every time the selected source event occurs.

:SOURce <name>
This command specifies a control source.
Usage
:SYSTem:MACRo:TRIGger:SOURce <name>
<name>
IMMediate
: Immediate triggering
MANual
: Manual trigger event
BUS
: Bus trigger event
EXTernal
: External trigger event
TIMer
: Timer trigger event
Details
This command specifies which control source is used as the trigger event for instrument readings. If
in the continuous trigger mode, the instrument continuously makes readings when the specified event
occurs. If in the one shot trigger mode, each event causes a single reading to occur.
With
IMMediate
selected, the trigger event is satisfied immediately. In
IMMediate
, readings are
made continuously.
With
MANual
selected, the trigger event occurs when the front panel
TRIG
key is pressed. Note that
the instrument must be in local in order for the
TRIG
key to be active.
With
BUS
selected, the trigger event occurs when a bus trigger (
*TRG
or
GET
) is sent. With
EXTernal
selected, the trigger event occurs when an input trigger is received through the rear panel EXT TRIG
IN connector.
While in the one shot mode, with
TIMer
selected, trigger events occur at a programmed timer
interval. Each time the programmed interval elapses, a reading is triggered. Use
:TIMer <n>
(on page
14-150) to set the timer interval.
