Query Syntax
:STATus:PTIMebase:EVENt?
Description
Reads the precision timebase event register to determine the status of individual status bits. The decimal-weighted value of the register is returned. The only bit used is bit 0 (LOSS), which indicates loss of the time reference due to a change in the reference clock signal. 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 AND'ed, which results in setting true bit 11 (LOSS) of the Operation Status Register.

Bit Definitions
- LOSS
- A true indicates that the precision timebase (provided by an 86107A or 86108A module) has detected a time reference loss due to a change in the amplitude or frequency of the reference clock signal.
