## Query Syntax

    :STATus:TRIGger:EVENt?

## Description

Reads the Trigger Event Register to determine the status of individual status bits. The decimal-weighted value of the register is returned.

Reporting of event register bits in the status register system is controlled by the mask loaded into the enable register. All true event bits, that are enabled, are logically "OR"ed, which results in setting true bit 2 (TRIG) of the Operation Status Register.

## Bit Definitions

STER
  A true indicates that a software (qualified) trigger has occurred.
ATER
  When trigger sweep is set to Auto, a true indicates the wait period for a valid hardware or software (qualified) trigger has elapsed and an auto trigger has occurred.
AER
  A true indicates that hardware is armed and ready to trigger.
