Section 6: 9100 System Operation — SCPI Language 6-23
Final Width = 215mm
6.5.4.1 General
In addition to IEEE 488.2 status reporting the 9100 implements the Operation and
Questionable Status registers with associated 'Condition', 'Event' and 'Enable' commands.
The extra status deals with current operation of the instrument and the quality of
operations.
The structure of these two registers is detailed in Fig. 6.2, together with the nature of the
reported events. Access to the registers is detailed in the STATus subsystem of Sub-
Section 6.6 of this handbook.
6.5.4.2 SCPI Status Registers
The SCPI states are divided into two groups, reporting from the Operation or Questionable
Status event register. Each Status register has its own 'Enable' register, which can be used
as a mask to enable bits in the event register itself, in a similar way to that set by the
∗
ESE
command for the Standard Event status Register (ESR).
Each Status Register is associated with its own third 'Condition' register (not illustrated
in Fig. 6.2), in which the bits are not 'sticky', but are set and reset as the internal conditions
change.
Each Enable Register can be commanded to set its mask to enable selected bits in the
corresponding Event Register. All registers (Event, Enable and Condition) can be
interrogated by appropriate 'Queries' to divulge their bits' states.
6.5.4.3 Reportable SCPI States
Operation Status Event Register
The following 'sticky' bits are set by their associated conditions:
bit 0 CALIBRATING: a capacitance self-calibration operation is in progress.
bit 8 TESTING: the instrument is performing a self test.
bit 9 PRETESTING: the instrument is performing a power-up self test.
Questionable Status Event Register
The following 'sticky' bits are set by their associated conditions:
bit 4 TEMPerature: Thermocouple Reference Junction conditions doubtful
bit 9 INV OHM CURR 1: High/Low Current warning — outside specification
bit 10 INV OHM CURR 2: High/Low Current warning — change setting
