:STATus:OPERation:INSTrument:PTRansitionset / query

Sets or queries the positive transition filter. Setting a bit in the positive transition filter causes a 0 to 1 transition in the corresponding condition register bit to write a 1 in the corresponding event register bit.

Name	Type	Values	Description
positiveTransition	integer	1 - 65535	Bit mask for the positive transition filter.

:STATus:OPERation:INSTrument[:EVENt]?query

Returns the contents of the EVENt part of the status register to check whether an event has occurred since the last reading. Reading an EVENt register deletes its contents.

integer - Event register contents.

:STATus:QUEStionable:INSTrument:CONDition?query

Returns the contents of the CONDition part of the questionable instrument status register. Reading the CONDition register does not delete its contents.

integer - Condition bits in decimal representation.

:STATus:QUEStionable:INSTrument:ENABleset / query

Sets or queries the enable mask that allows true conditions in the EVENt part to be reported in the summary bit. If a bit in the ENABle part is 1 and the corresponding EVENt bit is true, a positive transition occurs in the summary bit.

Name	Type	Values	Description
<arg0>	integer	0 - 65535	Enable mask value.

:STATus:QUEStionable:INSTrument:ISUMmary<Channel>:CONDition?query

Returns the contents of the CONDition part of the status register for the selected instrument or measurement state. Reading the CONDition register does not delete its contents.

Name	Type	Values	Description
Channel	integer	1 - n	Selects the instrument.

integer - Condition bits in decimal representation.

:STATus:QUEStionable:INSTrument:ISUMmary<Channel>:ENABleset / query

Name	Type	Values	Description
<Channel>	integer	1 - n	Selects the instrument; the suffix <n> at Channel selects the instrument.

:STATus:QUEStionable:INSTrument:ISUMmary<Channel>:NTRansitionset / query

Sets or queries the negative transition filter for the selected channel summary register. Setting a bit causes a 1 to 0 transition in the corresponding condition register bit to set the associated event register bit.

Name	Type	Values	Description
NegativeTransition	integer	1 - 65535	Bit mask in decimal representation.

integer - Event bits in decimal representation from the queried negative transition status register.

STATus:QUEStionable:INSTrument:ISUMmary1:NTRansition?

:STATus:QUEStionable:INSTrument:ISUMmary<Channel>[:EVENt]?query

Returns the contents of the EVENt part of the status register for the specified channel summary. Reading the EVENt register clears its contents.

Name	Type	Values	Description
Channel	integer	1 - n	Status register channel index.

integer - Event bits in decimal representation.

:STATus:QUEStionable:INSTrument:NTRansitionset / query

Sets or queries the negative transition filter for the questionable instrument status register. A set bit causes a 1-to-0 transition in the corresponding condition register bit to set the matching event register bit.

Name	Type	Values	Description
NegativeTransition	integer	1 - 65535	Bit mask for the negative transition filter.

integer - Event bits in decimal representation from the queried negative transition/status register.

STATus:QUEStionable:INSTrument:ISUMmary1: NTRansition?

:STATus:QUEStionable:INSTrument[:EVENt]?query

Returns the contents of the EVENt part of the status register to check whether an event has occurred since the last reading. Reading an EVENt register deletes its contents.

integer - Event bits in decimal representation.

:STATus:QUEStionable:INSTrument:ISUMmary<Channel>:PTRansitionset / query

Sets or queries the positive transition filter for the instrument summary status of a channel. Setting a bit in the positive transition filter causes a 0 to 1 transition in the corresponding condition register bit to write a 1 in the corresponding event register bit.

Name	Type	Values	Description
Channel	integer	1 - n	Channel suffix selecting the instrument summary instance.
PositiveTransition	integer	1 - 65535	Bit mask for the positive transition filter.

STATus:QUEStionable:INSTrument:ISUMmary1:PTRansition?

:STATus:QUEStionable:INSTrument:PTRansitionset / query

Sets or queries the positive transition filter. Setting a bit in the positive transition filter causes a 0 to 1 transition in the associated condition register bit to write a 1 to the corresponding event register bit.

Name	Type	Values	Description
arg0	integer	1 - 65535	Positive transition filter value.

integer - Returns the positive transition filter setting.

STATus:QUEStionable:INSTrument:ISUMmary1:PTRansition?

:STATus:OPERation:CONDition?query

Reads the condition register of the STATus:OPERation register. The register indicates which actions the instrument is currently executing.

integer - Returns the current contents of the STATus:OPERation CONDition register as a bit-coded value.

:STATus:OPERation[:EVENt]?query

Reads the event part of the STATus:OPERation register. The register reports which actions the instrument has executed since the last reading.

integer - Returns the STATus:OPERation event register value as a bit-coded integer.

:STATus:QUEStionable:CONDition?query

Returns the condition register of the STATus:QUEStionable register. The register contains information about different states which can occur.

integer - Returns the current contents of the STATus:QUEStionable condition register as a bit-coded value.

:STATus:QUEStionable[:EVENt]?query

Reads the STATus:QUEStionable register. The returned value is a decimal number that represents the bit pattern of the queried register.

integer - Decimal number representing the bit pattern of the queried register.
