Status Structure 13-15
Questionable event status
The used bits of the questionable event register (shown in Figure 13-7) are described as
follows:
• Bit B7, calibration summary (Cal) — Set bit indicates that an invalid calibration con-
stant was detected during the power-up sequence. This error will clear after successful
calibration of Model 6514.
• Bit B14, command warning (Warn) — Set bit indicates that a signal oriented measure-
ment command parameter has been ignored.
Condition registers
As Figure 13-1 shows, each status register set (except the standard event register set) has a
condition register. A condition register is a real-time, read-only register that constantly updates
to reflect the present operating conditions of the instrument. For example, while Model 6514 is
in the idle state, bit B10 (Idle) of the operation condition register will be set. When the instru-
ment is taken out of idle, bit B10 clears.
