Run this block to align the phases for ch1 and ch2. This block should also work with compatible Tektronix AFG31XXX instruments. Params: connection : VisaConnection The VISA address (requires the CONNECTION_AFG31000 block). channel : select, default=ch1 Which channel is the reference? Returns: out : String Aligned channel phases

In this example, an Tektronix AFG31000 is used to generate two waveforms.

First the necessary blocks were added:

  • CONNECT_AFG31000
  • RESET_AFG31000
  • 2x FUNCTION_AFG31000
  • ALIGN_PHASES_AFG31000
  • OUTPUT_AFG31000
  • SAVE_STATE_AFG31000

The instrument address was set for each AFG31000 block. Ensure the OUTPUT_AFG31000 block has both channels turn on.

The blocks were connected as shown and the app was run. The SAVE_STATE_AFG31000 block can be used to save and recall the current state of the AFG. However, you must use a OUTPUT_AFG31000 block to turn the outputs back on.

An oscilloscope was connected to the AFG31000 resulting in waveform:
