STATus Subsystem (Remote Only Commands)
signal. All the bits are summary bits from lower-level event registers.
:STATus Subsystem Commands and Queries
The :STATus subsystem controls the SCPI-defined instrument status reporting structures.
Each status register has a set of five commands used for querying or masking that
particular register.
Numeric values for bit patterns can be entered using decimal or hexadecimal
representations. (i.e. 0 to 32767 is equivalent to #H0 to #H7FFF. It is also equal to all ones,
111111111111111) See the SCPI Basics information about using bit patterns for variable
parameters.
Operation Register
Operation Condition Query This query returns the decimal value of the sum of the bits in
the Status Operation Condition register.
The data in this register is continuously updated and reflects the current conditions.
Operation Enable This command determines which bits in the Operation Event register,
will set the Operation Status Summary bit (bit 7) in the Status Byte Register. The variable
<integer> is the sum of the decimal values of the bits you want to enable.
Bit Condition Operation
3 Power summary The instrument hardware has detected a power
unleveled condition.
4 Temperature summary The instrument is still warming up.
5 Frequency summary The instrument hardware has detected an unlocked
condition or a problem with the external frequency
reference.
8 Calibration summary The instrument has detected a hardware problem
while doing the automatic internal alignment
process.
9 Integrity summary The instrument has detected a questionable
measurement condition such as: bad timing, bad
signal/data, timeout problem, signal overload, or
“meas uncal”.
