*ESE 129

Reads and clears the contents of the Standard Event Status Register. The instrument returns a decimal value corresponding to the binary-weighted sum of all bits set in the register.

*ESR? Example output: 128

TRIG:TIM2:COUN 4
TRIG:TIM4:COUN 20

Sets and reads the timer delay. The delay is the period after the timer is triggered and before it generates a trigger event.

TRIG:TIM2:DEL 50E-6

Configures the alarm of the timer. When the timer is enabled, it starts immediately if configured for a start time in the past or future.

Specifies when timer events are generated. When ON or 1, a trigger event is generated immediately when the timer is triggered and again when the delay elapses; when OFF or 0, the event is generated when the timer elapses.

TRIG:TIM3:STAR:GEN ON

Indicates whether a timer-start event was ignored because of the event detector state.

Configures an alarm or a time in the future when the timer will start. When the timer is enabled, it starts immediately if the configured start time has already passed.

:TRIGger:TIMer<n>:STARt:SEConds <time>
:TRIGger:TIMer<n>:STARt:SEConds?

Sets or queries the event that starts trigger timer <n>. The stimulus can be any trigger event, or NONE to disable event processing and use the timer as a timer or alarm based on the start time.

Enables or disables the specified trigger timer. When enabled, the timer performs the delay operation; when disabled, there is no timer on the delay operation.
