• outputProtocolViolation: Device reported an output protocol error during transfer.
• inputProtocolViolation: Device reported an input protocol error during transfer.
• busError: Bus error occurred during transfer.
• operationAlreadyInProgress: Unable to queue the asynchronous operation because there is already an operation in progress.
• invalidSetup: Unable to start operation because setup is invalid (due to attributes being set to an inconsistent state).
• queueError: Unable to queue asynchronous operation.
• insufficientSystemResources: Insufficient system resources to perform necessary memory allocation.
• invalidBufferMask: Invalid buffer mask specified.

• serviceRequestNotReceived: Service request has not been received for the session.
• invalidAddressSpace: Invalid address space specified.
• invalidOffset: Invalid offset specified.
• invalidWidth: Invalid source or destination width specified.
• unsupportedOffset: Specified offset is not accessible from this hardware.
• nonequalSourceAndDestinationWidths: Cannot support source and destination widths that are different.
• sessionNotMapped: The specified session is not currently mapped.
• responseStillPending: A previous response is still pending, causing a multiple query error.
• noListeners: No Listeners condition is detected (both NRFD and NDAC are deasserted).
• notControllerInCharge: The interface associated with this session is not currently the controller in charge.
• notSystemController: The interface associated with this session is not the system controller.
• unsupportedOperation: The given session or object reference does not support this operation.
• interuptStillPending: An interrupt is still pending from a previous call.
• parityError: A parity error occurred during transfer.
• framingError: A framing error occurred during transfer.
• overrunError: An overrun error occurred during transfer. A character was not read from the hardware before the next character arrived.
• triggerNotMapped: The path from trigSrc to trigDest is not currently mapped.
• unsupportedAlignOffset: The specified offset is not properly aligned for the access width of the operation.
• invalidUserBuffer: A specified user buffer is not valid or cannot be accessed for the required size.
• resourceBusy: The resource is valid, but VISA cannot currently access it.
• unsupportedWidth: Specified width is not supported by this hardware.
• invalidParameter: The value of some parameter—which parameter is not known—is invalid.
• invalidProtocol: The protocol specified is invalid.
• invalidWindowSize: Invalid size of window specified.
• windowMapped: The specified session currently contains a mapped window.
• unimplementedOperation: The given operation is not implemented.
• invalidLength: Invalid length specified.
• invalidMode: The specified mode is invalid.
• sessionNotLocked: The current session did not have any lock on the resource.
• memoryNotShared: The device does not export any memory.
• libraryNotFound: A code library required by VISA could not be located or loaded.
• unsupportedInterrupt: The interface cannot generate an interrupt on the requested level or with the requested statusID value.
• invalidLineParameter: The value specified by the line parameter is invalid.
• fileAccessError: An error occurred while trying to open the specified file. Possible reasons include an invalid path or lack of access rights.
• fileIOError: An error occurred while performing I/O on the specified file.
• unsupportedLine: One of the specified lines (trigSrc or trigDest) is not supported by this VISA implementation, or the combination of lines is not a valid mapping.
• unsupportedMechanism: The specified mechanism is not supported by the given event type.
• interfaceNumberNotConfigured: The interface type is valid but the specified interface number is not configured.
• connectionLost: The connection for the given session has been lost.
• machineNotAvailable: The remote machine does not exist or is not accepting any connections.
• machineAccessDenied: Access to the remote machine is denied.
• unknownCVISAError: An unknown CVISA error status was returned from a call to CVISA. The status of this code is stored in status.
• couldNotDecode: Could not decode the message into the specified type.
• invalidRequestKey: The provided request key was invalid.
• invalidInstrumentIdentifier: The provided instrument identifier did not adhere to the NI-VISA standard.
