## Bit Definitions

CAL
  A true indicates that an enabled bit in the calibration event status register has been set by a calibration completing
OVLD-ALL
  True indicates that an enabled bit in the Overload All event register has been set. Use this when you are using a multiple-oscilloscope system.
OVLD
  True indicates that an enabled bit in the Overload event register has been set. Use this when you are using a single-oscilloscope with eight or fewer channels.
LTEST
  A true indicates that an enabled bit in the limit test event status register has been set by a limit test completing or failing.
CLIP-ALL
  A true indicates that an enabled bit in the Clipped All event status register has been set. Use this when you are using a multiple-oscilloscope system.
CLIP
  A true indicates that an enabled bit in the Clipped event status register has been set. Use this when you are using a single-oscilloscope with eight or fewer channels.
TRIG
  True indicates that an enabled bit in the Trigger event register has been set.
ADER
  True indicates that an enabled bit in the Acquisition Done event register has been set by a completed acquisition.
