Data Questionable Modulation Event Register
The Data Questionable Modulation 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:MODulation[:EVENt]?
Data Questionable Modulation Event Enable Register
The Data Questionable Modulation Event Enable Register lets you choose which bits in the
Data Questionable Modulation Event Register set the summary bit (bit 7 of the Data
Questionable Condition Register) to 1.
Command:
STATus:QUEStionable:MODulation:ENABle <value> command 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 is set to 1, the Data
Questionable Modulation summary bit of the Data Questionable Condition
Register is set to 1. Send the command STAT:QUES:MOD:ENAB 520 (512 + 8).
Query:
STATus:QUEStionable:MODulation:ENABle?
Response:
Decimal value of the sum of the bits previously enabled with the
STATus:QUEStionable:MODulation:ENABle <value> command.
