Agilent 71612 Series Status Reporting
The Agilent 71612 Series has powerful status and reporting features which give important
information about events and conditions within the instrument, for example flag the end of
a measurement or perhaps indicate a command error. To access this information requires
interrogating a set of registers using Standard Commands for Programmable Instruments
(SCPI).
Internal Registers
The registers contained in the Agilent 71612 Series are as follows:
The internal registers are read using a combination of SCPI common commands and SCPI
status commands. The method of reading each register is explained in the following
sections.
