ML24xxA Native Commands GPIB Operation
8-16 PN: 10585-00001 Rev. P ML2437A/38A OM/PM
*SRE? (Return Service Request Enable register)
*STB? (Return Status Byte register)
*TRG (Perform the GPIB 'Group Execute Trigger' command)
*TST? (Self Test)
Syntax: *SRE?
Remarks: Returns the Service Request Enable register.
Syntax: *STB?
Remarks: Returns the status byte value with bit 6 replaced with the MSS value.
MSS is the GPIB Master Summary Status, and indicates that the device
has at least one reason for requesting service. Although the MSS
message is sent in bit position 6 of the device’s response to the *STB?
query, it is not sent in response to a serial poll and should not be
considered part of the IEEE 488.1/2 status byte. MSS = the Status Byte
(STB) OR’ed with the Service Request Enable register (SRE). Unlike the
*ESR? Command, this command does not clear the register afterwards.
Syntax: *TRG
Remarks: Performs a 'GET' command. The GT0, GT1 and GT2 commands set the
response to the GET or *TRG commands. When the ML2430 Series is
triggered using this command or the 488.1 hardware trigger, a trigger
and output for each display channel that is not OFF gives a response in
the output queue. If both display channels are displayed, there will be
two messages in the output queue to be read out.
