4 Programming the Status Register System
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.
Data Questionable Power Status Group
Some of the bits in this status group do not apply to the N8211A/N8212A and returns zero
when queried. See Table 4-8 on page 169 for more information.
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.
