Status Reporting Commands
Use the following commands to access the Status System Registers.
See the table on page 251 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 in the event register.
• 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.
