Programming the Status Register System
The Data Questionable 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 register will clear the content of that register. To query the
event register, send the command STATus:QUEStionable:POWer[:EVENt]?
Figure 1-31.
The Data Questionable Power Status Group also contains a Data Questionable Power
Event Enable Register. This register lets you choose which bits in the Data Questionable
Power Event Register will set the summary bit (bit 3 of the Data Questionable Condition
Register) to 1. Send the STATus:QUEStionable:POWer:ENABle <num> command where
<num> is the sum of the decimal values of the bits you want to enable. For example, to
enable bit 9 and bit 3 so that whenever either of those bits is set to 1, the Data
Questionable Power summary bit of the Data Questionable Condition Register will be set
to 1, send the command STAT:QUES:POW:ENAB 520 (512 + 8). The command
STATus:QUEStionable:POWer:ENABle? returns the decimal value of the sum of the bits
previously enabled with the STATus:QUEStionable:POWer:ENABle <num> command.
