6.6 Common Command List
6.6.1 *IDN?
Read the instrument’s identification string which contains four fields separated by
commas. The first field is the manufacturer’s name, the second field is the model
number, the third field is the serial number, and the fourth field is a revision code
which contains four numbers separated dots and a fifth number separated by a dash:
Keysight Technologies, M8195A,<serial number>, x.x.x.x-h
x.x.x.x= Soft Front Panel revision number, e.g. 2.0.0.0
h= Hardware revision number
Clear the event register in all register groups. This command also clears the error
queue and cancels a *OPC operation. It doesn’t clear the enable register.
Enable bits in the Standard Event Status Register to be reported in the Status Byte.
The selected bits are summarized in the “Standard Event” bit (bit 5) of the Status
Byte Register. The *ESE? query returns a value which corresponds to the binary-
weighted sum of all bits enabled decimal by the *ESE command. These bits are not
cleared by a *CLS command. Value Range: 0–255.
Query the Standard Event Status Register. Once a bit is set, it remains set until
cleared by a *CLS (clear status) command or queried by this command. A query of
this register returns a decimal value which corresponds to the binary-weighted sum
of all bits set in the register.
Set the “Operation Complete” bit (bit 0) in the Standard Event register after the
previous commands have been completed.
