RETURN_ERRORS_33510B

Return error messages from a supported function generator. Error retrival is first-in-first-out (FIFO). Returning errors clears them from the instruments queue. Requires a CONNECTION_33510B node at the start of the app to connect with the instrument. The VISA address will then be listed under 'connection'. This node should also work with compatible Keysight 33XXX wavefunction generators (although they are untested). Params: connection : VisaConnection The VISA address (requires the CONNECTION_MDO3XXX node). Returns: out : DataContainer String: Returns all errors in the WFG memory.

Python Code

from flojoy import flojoy, DataContainer, String, VisaConnection
from typing import Optional


@flojoy(inject_connection=True)
def RETURN_ERRORS_33510B(
    connection: VisaConnection,
    default: Optional[DataContainer] = None,

In this example, we return errors that the Keysight 33510B has generated.

Note

The 33510B nodes should also work with other 33XXX wavefunction generators. However, these are untested as of yet.

We must first add the CONNECTION_33510B node. This will create the connection to the instrument at the beginning of the app. To allow this we must set the VISA address for this (and all subsequent 33510B nodes). If the address does not appear in the parameters you may have to press REFRESH in the HARDWARE MANAGER tab.

We add the RETURN_ERRORS_33510B node as well as the TEXT_VIEW node to view the summary of the error.

In this case 0 No error is returned, but in the case of an actual error, the specific error will appear.
