Programming the Status Register System
Status Groups
Data Questionable BERT Transition Filters (negative and positive)
The Data Questionable BERT 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 BERT Event Register
The Data Questionable BERT 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 BERT Event Enable Register
The Data Questionable BERT Event Enable Register lets you choose which bits in the Data
Questionable BERT Event Register set the summary bit (bit 3 of the Data Questionable Condition
Register) to 1.
Commands:
STATus:QUEStionable:BERT:NTRansition (negative transition), or
STATus:QUEStionable:BERT:PTRansition (positive transition), where
is the sum of the decimal values of the bits you want to enable.
Queries:
STATus:QUEStionable:BERT:NTRansition? STATus:QUEStionable:BERT:PTRansition?
Query: STATus:QUEStionable:BERT[:EVENt]?
Command: STATus:QUEStionable:BERT:ENABle where is the sum of the decimal values of the
bits you want to enable
Example: Enable bit 11 and bit 2 so that whenever either of those bits are set to 1, the Data Questionable BERT
summary bit of the Data Questionable Condition Register is set to 1. Send the command
STAT:QUES:BERT:ENAB 520
(2048 + 4).
Query: STATus:QUEStionable:BERT:ENABle?
Response: Decimal value of the sum of the bits previously enabled with the
STATus:QUEStionable:BERT:ENABle
command.
