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> where <value> is the sum of the decimal values 
of the bits you want to enable. 
Example: Enable bit 4 and bit 3 so that whenever either of those bits are 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 (16 + 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.
