Status Groups
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 are 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.
