Commands Reference
:STATus Subsystem
Comments
The Operation Condition Status Register is cleared at power-on.
:STATus:OPERation:ENABle <non-decimal numeric> | <NRf>
Sets or queries the Operation Event Status Enable Register.
The parameter and query response value, when rounded to an integer value and
expressed in base 2 (binary), represents the bit values of the Operation Event Status
Enable Register. The value of unused bits is zero when queried and ignored when
set.
This register is used to enable a single or inclusive OR group of Operation Event
Status Register events to be summarized in the Status Byte Register (bit 7).
Range
The range for the <non-decimal numeric> or <NRf> parameter is
0 to 65,535.
Query Response
Numeric data transferred as ASCII bytes in <NR1> format.
• At power-on and :STAT:PRES, the Operation Event Status Enable Register is
Comments
cleared (value is 0).
• This value is unaffected by *RST and save/recall.
:STATus:OPERation[:EVENt]?
Queries the status of the Operation Event Status Register.
The Operation Event Status Register captures changes in conditions by having each
event bit correspond to a specific condition bit in the Operation Condition Status
Register. An event becomes TRUE when the associated condition makes the
transition specified by the transition filters. The event bits, once set, are "sticky."
That is, they cannot be cleared, even if they do not reflect the current status of a
related condition, until they are read.
• Numeric data transferred as ASCII bytes in <NR1> format.
Query Response
• Range is 0 to 65,535.
• The query response value is an integer formed by the binary weighting of bits.
The value of unused bits is zero.
