:ST A Tus: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
conguration):
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 P ower for that wavelength).
Bit 9, which can reect that the temperature in the laser heat
chamber is out of range (stabilizing).
Bit 10, which can reect 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$
:ST A Tus: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 .
:ST A Tus: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$
