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.
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.
Query: STATus:QUEStionable:MODulation[:EVENt]?
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.
