Standard Operation Transition Filters (negative and positive)

The Standard Operation Transition Filters specify which types of bit state changes in the

condition register set corresponding bits in the event register. Changes can be positive (0 to 1)

or negative (1 to 0).

Standard Operation Event Register

The Standard Operation Event Register latches transition events from the condition register

as specified by the transition filters. Event registers are destructive read only. Reading data

from an event register clears the content of that register.

Standard Operation Event Enable Register

The Standard Operation Event Enable Register lets you choose which bits in the Standard

Operation Event Register set the summary bit (bit 7 of the Status Byte Register) to 1

Commands:

STATus:OPERation:NTRansition <value> (negative transition), or

STATus:OPERation:PTRansition <value> (positive transition), where

<value> is the sum of the decimal values of the bits you want to enable.

Queries:

STATus:OPERation:NTRansition?

STATus:OPERation:PTRansition?

Query: STATus:OPERation[:EVENt]?

Command: STATus:OPERation:ENABle <value>, where

<value> is the sum of the decimal values of the bits you want to enable.

Example: To enable bit 9 and bit 3 so that whenever either of those bits is set to 1, the

Standard Operation Status summary bit of the Status Byte Register is set to 1.

Send the command STAT:OPER:ENAB 520 (512 + 8).

Query: STATus:OPERation:ENABle?

Response: Decimal value of the sum of the bits previously enabled with the

STATus:OPERation:ENABle <value> command.
