Status Reporting Commands
Use the following commands to access the Status System Registers.
Status Byte Register Commands
See the table on page 270 for the register bit definitions.
*STB?
Query the summary (condition) register in this register group. This command is
similar to a Serial Poll but it is processed like any other instrument command. This
command returns the same result as a Serial Poll but the "Master Summary" bit
(bit 6) is not cleared by the *STB? command.
*SRE <enable value>
*SRE?
Enable bits in the Status Byte to generate a Service Request. To enable specific
bits, you must write a decimal value which corresponds to the binary-weighted
sum of the bits in the register. The selected bits are summarized in the "Master
Summary" bit (bit 6) of the Status Byte Register. If any of the selected bits change
from "0" to "1", a Service Request signal is generated. The *SRE? query returns a
decimal value which corresponds to the binary-weighted sum of all bits enabled
by the *SRE command.
– A *CLS (clear status) does not clear the enable register but it does clear all bits
– A STATus:PRESet does not clear the bits in the Status Byte enable register.
– A *PSC 0 preserves the contents of the enable register through power cycles.
