Operation Status Registers

As shown in the status model's
register sets associated with operation status. Commands are summarized in the
contents (on page E-1) topic. Note that bits can also be set by using numeric parameter values. For
details, see Programming enable and transition registers
For example, either of the following commands will set the CAL enable bit (B0):
status.operation.enable = status.operation.CAL
status.operation.enable = 1
When reading a register, a numeric value is returned. The binary equivalent of this value indicates
which bits in the register are set. For details, see
following command will read the Operation Status Enable Register:
print(status.operation.enable)
Commands to program and read the register are summarized in the
page E-4) table.
Operation Status Registers
This register set feeds to bit B7 (OSB) of the Status Byte. The bits used in the Operation Status
Register set are described as follows:
•
Bit B0, Calibrating (CAL): Set bit indicates that one or more channels are calibrating.
•
Bit B3, Sweeping (SWE): Set bit indicates that one or more channels are sweeping.
•
Bit B4, Measuring (MEAS): Bit will be set when taking an overlapped measurement, but it will
not set when taking a normal synchronous measurement.
•
Bit B10, Trigger Overrun (TRGOVR): Set bit indicates that an enabled bit in the Operation
Status Trigger Overrun Summary Register is set.
•
Bit B11, Remote Summary (REM): Set bit indicates that an enabled bit in the Operation Status
Remote Summary Register is set.
•
Bit B12, User (USER): Set bit indicates that an enabled bit in the Operation Status User Register
is set.
•
Bit B13, Instrument Summary (INST): Set bit indicates that an enabled bit in the Operation
Status Instrument Summary Register is set.
•
Bit B14, Program Running (PROG): Set bit indicates that a program is running.
