STATus Commands
STATus Commands
Status commands let 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.
Instrument status is also programmed using the Common commands: *CLS, *ESE, *ESR?, *OPC, *OPC?, *SRE,
*STB? and *WAI discussed at the end of this topic. Common commands control additional status functions such as the
Service Request Enable and the Status Byte registers. Refer to
STATus:OPERation[:EVENt]?
Queries the
event register
that are passed by the Operation NTR and PTR filter. Reading the Operation Status Event register clears it.
Parameter
(none)
Read the operation status event register: STAT:OPER?
*RST has no effect on this register.
l
The value returned is the binary-weighted sum of all bits set in the register.
l
STATus:OPERation:CONDition?
Queries the
condition register
(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 condition register bits reflect the current condition. If a condition goes away, the corresponding bit is cleared.
l
The value returned is the binary-weighted sum of all bits set in the register.
l
STATus:OPERation:ENABle < value >
STATus:OPERation:ENABle?
Sets and queries bits in the
specific bits from the Operation Event register to set the OPER (operation summary) bit of the Status Byte register.
STATus:PRESet clears all bits in the enable register.
Parameter
A decimal value that corresponds to the binary-
weighted sum of the bits in the register.
Enable bit 3 and 4 in the enable register: STAT:OPER:ENAB 24
