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.
