enabled in the status byte register. The selected bits are summarized in the "master summary" bit (bit6)
of the status byte register. If any of the selected bits change from 0 to 1, the instrument generates a
Service Request signal.
When <value> is set to 0, executing this command will clear the enable register of the status byte
register.
If you have configured the instrument by using the *PSC
1 command, the enable register of the
standard event register will be cleared at the next power-on of the instrument. If you have configured
the instrument by using the
*PSC 0 command, the enable register of the standard event register will
not be cleared at the next power-on of the instrument.
Return Format
The query returns a decimal value that corresponds to the binary-weighted sum of the bits enabled in the
status byte register.
*STB?
Syntax
*STB?
Description
Queries the status register of the status byte register.
Remarks
This command cannot clear the service request. Bit6 (master summary bit) of the status byte register will
not be cleared as long as the condition that generates the service request is still in effect.
Return Format
The query returns a decimal value that corresponds to the binary-weighted sum of all the bits in the status
register of the status byte register.
*TRG
Syntax
*TRG
Description
Triggers a sweep or a burst.
Remarks
You can only trigger the sweep or burst via the remote interface when the sweep or burst function is
currently enabled and the trigger source is set to manual (use the
[:SOURce[<n>]]:SWEep:TRIGger:SOURce or [:SOURce[<n>]]:BURSt:TRIGger:SOURce command).
You can also send the
[:SOURce[<n>]]:SWEep:TRIGger[:IMMediate] or
[:SOURce[<n>]]:BURSt:TRIGger[:IMMediate] command to trigger a sweep or a burst when the
sweep or burst function is currently enabled and the trigger source is set to manual.
