Chapter 3122
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.
Query: STATus:QUEStionable:CONDition?
Response: The decimal sum of the bits set to 1
Example: The decimal value 520 is returned. The decimal sum = 512 (bit 9) + 8 (bit 3).
Commands:
STATus:QUEStionable:NTRansition <value> (negative), or
STATus:QUEStionable:PTRansition <value> (positive), 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]?
