:STATus:QUEStionable[:EVENt]?
Syntax :STATus:QUEStionable [ :EVENt ] ?
Description This query reads the contents of the QUEStionable:EVENt
register. Only three bits of the event register are used (whether
these bits contain information depends on the transition register
conguration):
Bit 7, which is 1 when coherence control has been activated
and the chosen power level is too low (that is, below the
Coherence Control Uncalibrated Power for that wavelength).
Bit 9, which can reect that the temperature in the laser heat
chamber is out of range (stabilizing).
Bit 10, which can reect that the output has been switched
o to protect the laser diode.
Example OUTPUT 724;":STAT:QUES:PTR 1536"
OUTPUT 724;":STAT:QUES:COND?"
ENTER 724;A$
:STATus:QUEStionable:NTRansition
Syntax :STATus:QUEStionable:NTRansition < wsp >< value >
Description This command sets the bits in the NTRansition register. Setting
a bit in this register enables a negative transition (1 ! 0) in the
corresponding bit in the CONDition register to set the bit in the
EVENt register.
:STATus:QUEStionable:NTRansition?
Syntax :STATus:QUEStionable:NTRansition?
Description This query returns the current contents of the
QUEStionable:NTRansition register.
Example OUTPUT 724;":STAT:QUES:NTR 768"
OUTPUT 724;":STAT:QUES:NTR?"
ENTER 724;A$
