Usage
:STATus:QUEStionable[:EVENt]?
Details
This query reads the contents of the questionable status event register. After sending this command and
addressing the Model 2450 to talk, a value is sent to the computer. This value indicates which bits in the
appropriate register are set.
The Questionable Register can be set to the numeric equivalent of the bit to set. To set more than one bit of the
register, set the Questionable Register to the sum of their decimal weights. For example, to set bits B12 and
B13, set the Questionable Register to 12,288 (which is the sum of 4,096 + 8,192).
Example
:STAT:QUES?
Query the Questionable Register.
