STATus:OPERation:CONDition?
STATus:OPERation:CONDition?

which are part of the instrument’s operation. The switch module driver
does not set bit 8 in this register (see STATus:OPERation[:EVENt]?).

*ESE 61 unmasks standard event register bits 0,
2, 3, 4 and 5 (*ESE 128 only unmasks bit 7).

the status byte register. This is effective
only if the STAT:OPER:ENAB 256 command
is executed.
