OUTPUT_SYNC_33510B

Download Flojoy Studio to try this app

Sync multiple output phases of a supported function generator. Can only be turned on for one channel. 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). on_off : str Whether to turn the waveform phase syncing on or off. channel : str The channel to use as the baseline phase. Returns: out : DataContainer String: The channel, and ON or OFF depending on on_off value.

In this example, we sync the waveform output phases generation for a Keysight 33510B. Each channel in the 33510B has a phase which results in shifting the wavefunction in the x axis (i.e. time). One channel should be chosen as the baseline for this phase to ensure the phases match for the two channels (the phase of the second channel is then with respect to the baseline channel).

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 OUTPUT_SYNC_33510B node as well as the TEXT_VIEW node to view the summary of the changes.

We then must set the node parameters. First, the VISA address must be set for all nodes as mentioned above. Then the reference channel must be set as well as whether to turn the output sync on or off. You can also use this node to query the current output sync settings on the instrument.
