Operation Status Registers

As shown in the status model's Operation status registers (on page E-9) diagram, there are 22

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 (on page E-14).

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 Reading registers (on page E-15

). For example, the

following command will read the Operation Status Enable Register:

print(status.operation.enable)

Commands to program and read the register are summarized in the Status function summary (on

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

• 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.

For more information on the Operation Status Registers, refer to Status register set contents (on page

E-1) and the figures in this appendix.
