Programming the Status Register System
Status Groups
Data Questionable Transition Filters (negative and positive)
The Data Questionable Transition Filters specify which type 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).
Data Questionable Event Register
The Data Questionable 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.
Data Questionable Event Enable Register
The Data Questionable Event Enable Register lets you choose which bits in the
Data Questionable Event Register set the summary bit (bit 3 of the Status Byte
Register) to 1.
Commands: STATus:QUEStionable:NTRansition <value> (negative transition), or
STATus:QUEStionable:PTRansition <value> (positive transition), where
<value> is the sum of the decimal values of the bits you want to enable.
Queries: STATus:QUEStionable:NTRansition?
STATus:QUEStionable:PTRansition?
Query: STATus:QUEStionable[:EVENt]?
Command: STATus:QUEStionable:ENABle <value> where <value> is the sum of the decimal values
of the bits you want to enable.
Example: Enable bit 9 and bit 3 so that whenever either of those bits are set to 1, the Data Questionable Status
summary bit of the Status Byte Register is set to 1. Send the command STAT:QUES:ENAB 520
(512 + 8).
Query: STATus:QUEStionable:ENABle?
Response: Decimal value of the sum of the bits previously enabled with the
STATus:QUEStionable:ENABle <value> command.
