STATus:OPERation:NTR

STATus:OPERation:PTR

These commands set or read the value of the Operation NTR (Negative-Transition) and PTR (Positive- Transition) registers. These registers serve as polarity filters between the Operation Enable and Operation Event registers to cause the following actions:

KWhen a bit in the Operation NTR register is set to 1, then a 1-to-0 transition of the corresponding bit in the Operation Condition register causes that bit in the Operation Event register to be set.

KWhen a bit of the Operation PTR register is set to 1, then a 0-to-1 transition of the corresponding bit in the Operation Condition register causes that bit in the Operation Event register to be set.

KIf the same bits in both NTR and PTR registers are set to 1, then any transition of that bit at the Operation Condition register sets the corresponding bit in the Operation Event register.

KIf the same bits in both NTR and PTR registers are set to 0, then no transition of that bit at the Operation Condition register can set the corresponding bit in the Operation Event register.

STATus:PRESet

This command sets all defined bits in the Status Subsystem PTR registers and clears all bits in the subsytem NTR and Enable registers.

Command Syntax	STATus:PRESet
Parameters	None
Examples	STAT:PRES STATUS:PRESET

STATus:QUEStionable[:EVENt]?

This query returns the value of the Questionable Event register. The Event register is a read-only register that stores (latches) all events that are passed by the Questionable NTR and/or PTR filter. Reading the Questionable Event register clears it.

Query Syntax

Parameters

None

STAT:QUES? (@1)

Returned Parameters
