logically OR-ed to cause the MSS bit of the Status Byte register to be set. Refer to Status Tutorial for
more information.
The query reads the enable register and returns a decimal value which corresponds to the binary-
weighted sum of all bits set in the register.
Parameter Typical Return
A decimal value that corresponds to the binary-weighted sum of the bits
in the register.
<bitvalue>
Enable bit3 and 4 in the enable register: *SRE 24
l When a serial poll is conducted in response to a service request, RQS is cleared but MSS is not.
l When *SRE is cleared (by programming it with 0), the power system cannot generate a service
request.
*STB?
Status Byte Query. Reads the Status Byte Register, which contains the status summary bits and the
Output Queue MAV bit. The Status Byte is a read-only register and the bits are NOT cleared when it is
read. Refer to Status Tutorial for more information.
Parameter Typical Return
(none) <bitvalue>
Read status byte: *STB?
l The status summary bits are cleared when the appropriate event registers are read. The MAV bit
is cleared at power-on, by *CLS, or when there is no more response data available.
l When a serial poll is conducted in response to a service request, RQS is cleared, but MSS is not.
*TRG
Trigger Command. Generates a trigger when the trigger system has BUS selected as its source. The
command has the same affect as the Group Execute Trigger (<GET>) command).
Parameter Typical Return
(none) (none)
Generates an immediate trigger: *TRG
*TST?
SelfTest Query. Performs an instrument self-test. A 0 (zero) indicates the instrument passed self-test.
If self-test fails, one or more error messages will provide additional information. Use SYSTem:ERRor?
to read the error queue. See SCPI Error Messages for more information.
