Status Registers
Use Status Registers to Determine the State of Analyzer Events and Conditions
:STATus:QUEStionable:CALibration:NTRansition <num> (negative
transition) or :STATus:QUEStionable:CALibration:PTRansition
<num> (positive transition) where <num> is the sum of the decimal values of the
bits you want to enable.
The Questionable Status Calibration Event register latches transition events from
the condition register as specified by the transition filters. Event registers are
destructive read-only. Reading data from an event register will clear the content of
that register. To query the event register, send the command
:STATus:QUEStionable:CALibration
[:EVENt]?
See “Questionable Status Event Enable Register” on page 77 for an explanation of
how to set the summary bit using the event enable register. In this case, use the
command :STATus:QUEStionable:CALibration:ENABle <num>.
Questionable Status Integrity Uncalibrated Condition and
Event Enable Registers
The Questionable Status Integrity Uncalibrated Condition Register continuously
monitors the calibration status of the analyzer. Condition registers are read-only.
To query the condition register, send the command
:STATus:QUEStionable:INTegrity:UNCalibrated:CONDition? The
response will be the decimal sum of the bits which are set to 1.
The transition filter specifies which types of bit state changes in the condition
register will set corresponding bits in the event register. The changes may be
positive (from 0 to 1) or negative (from 1 to 0). Send the command
:STATus:QUEStionable:INTegrity:UNCalibrated:NTRansition
<num> (negative transition) or
:STATus:QUEStionable:INTegrity:UNCalibrated:PTRansition
<num> (positive transition) where <num> is the sum of the decimal values of the
bits you want to enable.
The Questionable Status Integrity Uncalibrated Event Register latches transition
events from the condition register as specified by the transition filters. Event
registers are destructive read-only. Reading data from an event register will clear
the content of that register. To query the event register, send the command
:STATus:QUEStionable:INTegrity:UNCalibrated[:EVENt]?
See “Questionable Status Event Enable Register” on page 77 for an explanation of
how to set the summary bit using the event enable register. In this case, use the
command :STATus:QUEStionable:INTegrity:UNCalibrated:ENABle
<num>.
