Figure 6-8 Standard Operation Status Group
6.1.6.5 Standard Operation Status Group
The standard operation status group provides information about the state of the measurement
systems in the instrument. This status group is accessed through the STATus subsystem.
Standard operation status includes a condition register, event register, and an enable register.
Figure 6-8 illustrates the structure of standard operation status.
6.1.6.6 Standard Operation Status Condition Register
This is a 16-bit register gathering information about the state of the measurement systems in an
instrument. According to SCPI recommendation, we define:
BIT
Meaning (True = ‘1’)
0
Calibrating bit which is true when S/C trimming, O/C trimming, or
calibrating is in progress, and otherwise reset.
4
Measuring bit which is true when measurement is in progress, and
otherwise reset.
Other bits are unused and are 0.
6.1.6.7 Standard Operation Status Event Register
This is a 16-bit register; each event bit in the event register corresponds to a condition bit in the
standard operation status condition register. According to SCPI recommendation, we define:
