Channel Questionable Status SUMMARY Register
There are three channel questionable status Summary registers, one for each channel.
These registers provide information about voltage and current regulation as well as
overvoltage and overcurrent. bit0 (VOLTage) is set when the voltage becomes
unregulated, and bit1 (CURRent) is set when the current becomes unregulated.
Sending
:STATus:QUEStionable:INSTrument:ISUMmary[<n>][:EVENt]?
will read the
channel questionable status SUMMARY register of the corresponding channel. The
definitions of the bits in the channel questionable status SUMMARY register and the
decimal values corresponding to their binary weights are as shown in the table below.
