Data Questionable Frequency 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 Frequency Event Enable Register
Lets you choose which bits in the Data Questionable Frequency Event Register set the
summary bit (bit 5 of the Data Questionable Condition Register) to 1.
Query: STATus:QUEStionable:FREQuency[:EVENt]?
Command:
STATus:QUEStionable:FREQuency: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 is set to 1, the Data
Questionable Frequency summary bit of the Data Questionable Condition
Register is set to 1. Send the command STAT:QUES:FREQ:ENAB 520 (512 + 8).
Query: STATus:QUEStionable:FREQuency:ENABle?
Response: Decimal value of the sum of the bits previously enabled with the
STATus:QUEStionable:FREQuency:ENABle <value> command.
