STATus Subsystem
Status register programming lets you determine the operating condition of the instrument at any time.
The instrument has three groups of status registers; Operation, Questionable, and Standard Event. The
Operation and Questionable status groups each consist of the Condition, Enable, and Event registers
as well as NTR and PTR filters.
The Status subsystem is also programmed using Common commands. Common commands control
additional status functions such as the Service Request Enable and the Status Byte registers. Refer to
Status Tutorial
for more information.
STATus:OPERation[:EVENt]
Queries the
event register
(latches) all events that are passed by the Operation NTR and/or PTR filter. Reading the Operation
Status Event register clears it.
Parameter
(none)
Read the operation status event register: STAT:OPER?
The value returned is the binary-weighted sum of all enabled bits in the register. For example, with
l
bit 3 (value 8) and bit 5 (value 32) set and enabled, the query returns +40.
*RST has no effect on this register.
l
STATus:OPERation:CONDition?
Queries the
condition register
the live (unlatched) operational status of the instrument. Reading the Operation Status Condition
register does not clear it.
Parameter
(none)
Read the operation status condition register: STAT:OPER:COND?
The value returned is the binary-weighted sum of all enabled bits in the register. For example, with
l
bit 3 (value 8) and bit 5 (value 32) set and enabled, the query returns +40.
The condition register bits reflect the current condition. If a condition goes away, the cor-
l
responding bit is cleared.
*RST clears this register, other than those bits where the condition still exists after *RST.
