5-3 IEEE 488.2 / SCPI STATUS REGISTERS
IEEE 488.2 compliant instruments have at least two registers: the Status Byte and
the Standard Event Status Register. SCPI adds the Operation Status Register,
Questionable Status Register and Error/Event Queue. The diagram below, taken
from the SCPI standard, provides a good summary. This section describes how
the THM1176/TFM1186 uses these status registers.
