Operation Status Group

The Operation Status registers record signals that occur during normal operation. As shown below, the group consists of a Condition, PTR/NTR, Event, and Enable register. The outputs of the Operation Status register group are logically-ORed into the OPERation summary bit (7) of the Status Byte register.

Register

Command

Description

Condition

STAT:OPER:COND? (@<channel list>)

A register that holds real-time status of the circuits

 

 

being monitored. It is a read-only register.

PTR Filter

STAT:OPER:PTR <n> (@<channel list>)

A positive transition filter that functions as described

 

 

under STAT:OPER:NTRPTR commands in chapter 6.

 

 

It is a read/write register.

NTR Filter

STAT:OPER:NTR <n> (@<channel list>)

A negative transition filter that functions as described

 

 

under STAT:OPER:NTRPTR commands in chapter 6.

 

 

It is a read/write register.

Event

STAT:OPER:EVEN? (@<channel list>)

A register that latches any condition that is passed

 

 

through the PTR or NTR filters. It is a read-only

 

 

register that is cleared when read.

Enable

STAT:OPER:ENAB <n> (@<channel list>)

A register that functions as a mask for enabling specific

 

 

bits from the Event register. It is a read/write register.
