Standard Event
Status Enable
Register (ESE)
The Standard Event Status Enable Register allows one or more events
in the Standard Event Status Register to be reflected in the ESB
summary message bit. The Standard Event Status Enable Register is an
8-bit register that enables corresponding summary messages in the
Standard Event Status Register. Thus, the application programmer can
select reasons for the generator to issue an ESB summary message bit
by altering the contents of the ESE Register.
The Standard Event Status Enable Register is read with the *ESE?
Common query. The response to this query is a number that represents
the sum of the binary-weighted value of the Standard Event Status
Enable Register.
The Standard Event Status Enable Register is written using the *ESE
command followed by a decimal value representing the bit values of the
Register. A bit value one indicates an enabled condition. Consequently,
a bit value of zero indicates a disabled condition. The Standard Event
Status Enable Register is cleared by setting *ESE0. Summary of *ESE
messages is given in the following.
*ESE0
– No mask. Clears all bits in the register.
*ESE1
– ESB on Operation Complete.
*ESE2
– ESB on Request Control.
*ESE4
– ESB on Query Error.
*ESE8
– ESB on Device Dependent Error.
*ESE16
– ESB on Execution Error.
*ESE32
– ESB on Command Error.
*ESE64
– ESB on User Request.
*ESE128
– ESB Power on.
Error Messages
In general, whenever the Model 3153 receives an invalid SCPI command, it
automatically generates an error. Errors are stored in a special error queue and
may be retrieved from this buffer one at a time. Errors are retrieved in first-in-
first-out (FIFO) order. The first error returned is the first error that was stored.
When you have read all errors from the queue, the generator responds with a
0,"No error" message.
If more than 30 errors have occurred, the last error stored in the queue is
replaced with -350, “Queue Overflow”. No additional errors are stored until you
remove errors from the queue. If no errors have occurred when you read the
error queue, the generator responds with 0,"No error".
The error queue is cleared when power has been shut off or after a *CLS
command has been executed. The *RST command does not clear the error
queue. Use the following command to read the error queue:
