Agilent Technologies 34420A User Manual

STATus:OPERation:EVENt?
This command queries the Questionable Data event register. The meter
returns a decimal value which corresponds to the binary-weighted sum of
all bits set in the register. Only bit 8 (decimal 256) is used and latches
the digital filter settled state of the condition register.
STATus:PRESet
This command clears all bits in the Questionable Data enable and
Operational Status enable registers.
*CLS
This command clears the Status Byte summary register and all event
registers.
*ESE < enable value >
This command enables bits in the Standard Event enable register. The
selected bits are then reported to the Status Byte.
*ESE?
This command queries the Standard Event enable register. The meter
returns a decimal value which corresponds to the binary-weighted sum of
all bits set in the register.
*ESR?
This command queries the Standard event register. The meter returns a
decimal value which corresponds to the binary-weighted sum of all bits
set in the register.
*OPC
This command sets the “operation complete” bit (bit 0) in the Standard
Event register after the command is executed.
*OPC?
This command returns “1” to the output buffer after the command is
executed.
