*SRE <NRf> — service request enable command
This command sets or clears the individual bits of the Service Request Enable Register.
Usage
*SRE 1
*SRE 32
Details
The individual bits of the Service Request Enable Register can be set or cleared by using the *SRE common
command. To read the Service Request Enable Register, use the *SRE? query command. The Service Request
Enable Register clears when power is cycled or a parameter value of 0 is sent with the *SRE command (for
example, *SRE 0).
Set the instrument for an SRQ interrupt by using *SRE 32.
*SRE? — service request enable command query
This command queries the Status Byte Enable Register.
Usage
*SRE?
Details
The instrument returns a decimal value which corresponds to the binary-weighted sum of all bits set in the
register.
*STB? — status byte query
The *STB? command is similar to a serial poll, but it is processed like any other instrument command.
Usage
*STB?
Details
The *STB? command returns the same result as a serial poll, but the “request service” bit (bit 6) is not cleared if
a serial poll has occurred.
*TRG — trigger command
Use the *TRG command to issue a trigger to the instrument. It has the same effect as a group
execute trigger (GET).
Usage
*TRG
Details
Use the *TRG command as an event to control operation. The instrument reacts to this trigger if BUS is the
programmed arm control source. The control source is programmed from the TRIGger subsystem.
