COPY_AFG31000

Copy the setup parameters to the other channel. 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 to copy to the other channel. Returns: out : String Placeholder

In this example, an Tektronix AFG31000 is used to generate an arbitrary waveform.

First the necessary blocks were added:

  • CONNECT_AFG31000
  • COPY_AFG31000
  • ARBITRARY_AFG31000
  • BASIC_PARAMETERS_AFG31000
  • OUTPUT_AFG31000
  • 3x BASIC_OSCILLATOR
  • MULTIPLY
  • LINE

The instrument address was set for each AFG31000 block. Ensure the OUTPUT_AFG31000 block has channel 1 output turned on. Note the COPY_AFG31000 block is rename PLACEHOLDER here and it preset for block running order reasons. The BASIC_PARAMETERS_AFG31000 block is used to change frequency, offset, voltage, and phase for a single channel, without changing the function itself.

The blocks were connected as shown and the app was run. The 3 BASIC_OSCILLATOR blocks were used to generate the arbitrary waveform. Any waveform generated in Flojoy can be used as the input for ARBITRARY_AFG31000 to allow for any output.

An oscilloscope was connected to the AFG31000 resulting in waveform:
