Bit 3 - Device Dependent Error. This bit is set when an error in a
device function occurs. For example, the following command will
cause a DDE error:
VOLTage 5;:VOLTage:OFFSet 2
Both of the above parameters are legal and within the specified
limits, however, the generator is unable to generate such an
amplitude and offset combination.
Bit 4 - Execution Error. This bit is generated if the parameter
following the command is outside of the legal input range of the
generator.
Bit 5
– Command Error. This bit indicates the generator received a
command that was a syntax error or a command that the device
does not implement.
Bit 6 - User Request. This event bit indicates that one of a set of
local controls had been activated. This event bit occurs regardless
of the remote or local state of the device.
Bit 7 - Power On. This bit indicates that the device's power source
was cycled since the last time the register was read.
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.
