*SRE? SERVICE REQUEST ENABLE QUERY
Type: Status command
Function: An integer value representing the value of the Service Request Enable
Register is placed in the output queue. The possible values are listed
in the *SRE command section.
*STB? STATUS BYTE QUERY
Type: Status command
Function: The value of the Status Byte Register is put into the output queue.
Contrary to the "*ESR?" command, this register is not cleared by
reading it. The register will be zero only when all its related structures
are cleared, namely the Event Status Register (ESR) and the output
queue.
Bit: 76543210
Not used, should always be 0
MAV: Message Available bit
ESB: Event Status Bit
MSS: Master Summary Status bit
Not used, should always be 0
Bit 7 to 0 have a respective value of 128, 64, 32, 16, 8, 4, 2 and 1. For
example if bit 4 and 5 are set then the integer value is 48 (16+32).
Note that bit 6 is MSS, which does not necessarily have the same value
as RQS (see section 4.5.1 for more details).
*TRG TRIGGER
Type: Trigger command
Function: Trigger operation of the device. Since the DLS 50 has no functions
that can be triggered this command has no effect on the operation of
the unit.
