Status Registers
Use Status Registers to Determine the State of AnalyzerEvents and Conditions
Questionable Status Power Condition and Event Registers
The Questionable Status Power Condition Register continuously monitors output
power status of the analyzer. Condition registers are read-only. To query the
condition register, send the command
:STATus:QUEStionable:POWer:CONDition? The response will be the
decimal sum of the bits which are set to 1.
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 comman d
:STATus:QUEStionable:POWer:NTRansition <num> (negative
transition) or :STATus:QUEStionable:POWer:PTRansition <num>
(positive transition) where <num> is the sum of the decimal values of the bits you
want to enable.
The Questionable Status Power 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 r egister will clear the content of
that register. To query the event register, send the command
:STATus:QUEStionable:POWer[:EVENt]?
See “Questionable Status Event Enable Register” on page77 for an explanation of
how to set the summary bit using the event enable register. In this case, use the
command :STATus:QUEStionable:POWer:ENABle <num>.
