STATus Monitoring Commands
The STATus commands allow you to examine the status of the instrument by
monitoring the Operation Status register and the Questionable Data register.
Figure 5-1 shows all of the instrument‘s status registers.
The STATus system contains four registers (and the Output Queue), two of
which are under IEEE 488.2 control. These are the Standard Event Status
Register (ESR) and the Status Byte Register (SBR). The other two are the
Standard Operation Status register and Questionable Data register. Refer to the
Common command descriptions in Table 5-1 and the Status Reporting section of
this chapter for more details.
The two registers under the instrument‘s control are the Standard Operation
Status register and the Questionable Data register. These registers may be set and
queried.
Parameter Entry
Parameter entry for both registers is numeric only. Numeric types may be
Decimal, Hexadecimal, Octal, or Binary. The decimal numeric range is between
0 and 32767. The *RST value is 0. Sending a decimal value of 64 will set bit 6.

Using the Operation Status Register
The 16-bit Operation Status register monitors instrument operations currently
being performed. The instrument implements bits 0, 8, 9, 10, 11, and 12 to
monitor various internal operations. Refer to the Status Reporting section of this
chapter for definitions of these bits.
The Operation Status register group consists of a condition (C) register, an event
(EV) register, and an enable (EN) register as shown in Figure 5-1. The
commands in the STATus:OPERation subsystem control and monitor these
registers.
