SYNTAX
DESCRIPTION
The Set Event Mask (
turn, determine which Event Status Register (ESR) conditions are enabled to generate the Event Status Register
Bit (ESB) in the Serial Poll Status (SPS) Register. Multiple ESR bits can be enabled simultaneously by issuing
Set Event Mask (
Event Mask remains enabled until a Clear Event Mask (
Reset (
The following list outlines the possible conditions of the ESE:
: Sending this command clears the entire mask of the Event Status Enable (ESE) Register to zero.
N000
: Acquisition Complete. Sending this command allows the setting of the ESB if the unit has determined
N001
that the configured acquisition has completed.
: Stop Event. Sending this command allows the setting of the ESB when the pre-defined stop event of a
N002
configured acquisition has occurred.
: Query Error. This condition is set when an attempt is made to read data from the output queue when no
N004
data are present or data in the output queue were lost. Data may be lost when too many data are requested to
be buffered in the queue (for example, issuing multiple commands to return data without ever reading them).
: Device Dependent Error. This condition is set when a conflict in programmed parameters is detected.
008
This is also referred to as a conflict error.
: Execution Error. This condition is set when a parameter exceeds valid limits for a particular command.
N016
This is also referred to as Invalid Device Dependent Command Option (IDDCO) error.
: Command Error. This condition is set when an illegal command is sent to the unit. This is also referred
N032
to as Invalid Device Dependent Command (IDDC) error.
: Buffer 75% Full. Sending this command will allow the setting of the ESB when the unit has determined
N064
that the acquisition buffer is at least 75% full.
: Power On. This condition is set whenever unit is first powered up or a
