HP437B Emulation Commands GPIB Operation
8-106 PN: 10585-00001 Rev. P ML2437A/38A OM/PM
*STB? (Return Status Byte register)
*TST? (Self Test)
@1 (Set SRE mask)
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: *TST?
Remarks: Performs a self test and returns 000.'
