Status Registers
Use Status Registers to Determine the State of Analyzer Events and Condition s
Standard Event Status Registe r
The standard event status register is used to determine the specifi c
event that sets bit 5 in the status byte register. The standard event
status register does not have negative and positive transition registers,
nor a condition register. Use the IEEE common commands at th e
beginning of Chapter 5, "Language Reference" in this guide to acces s
the register.
To query the standard event status register, send the
*ESR
command .
The response will be the decimal sum of the bits which are set to 1. For
example, if bit number 7 and bit number 3 are set to 1, the decimal su m
of the 2 bits is 128 plus 8 . So the decimal value 136 is returned .
