Status Registers
Use Status Registers to Determine the State of Analyzer Events and Conditions
NOTE
All bits are summary bits from lower-level event registers. (For a general diagram
of the STATus:QUEStionable register, see
A Questionable Status condition register query response will be the decimal sum
of the bits which are set to 1. For example, if bit number 9 and bit number 3 are set
to 1, the decimal sum of the 2 bits is 512 plus 8. So the decimal value 520 is
returned.
The transition filter specifies which types of bit state changes in the condition
register will set corresponding bits in the event register. The changes may be
positive (from 0 to 1) or negative (from 1 to 0). Send the command
:STATus:QUEStionable:NTRansition <num>
(negative transition) or
:STATus:QUEStionable:PTRansition <num>
(positive transition) where
<num>
is the sum of the decimal values of the bits you want to enable.
The Questionable Status 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 will clear the content of that
register. To query the event register, send the command
:STATus:QUEStionable[:EVENt]?
