Configure Operation

Basic Tab

The Basic tab for the Configure operation contains the following options:

• Output Mode —Determines how the function generator produces waveforms. This setting determines the extension group that includes the functions and settings to use to configure the waveform the function generator produces.

  Supported Value	Description
  Standard Function (0)	Uses standard function settings to configure the output signals of the function generator.
  Arb Waveform (1)	Uses the settings on the Waveforms tab to configure the output signals of the function generator.
  Sequence (2)	Uses the settings on the Sequences tab to configure the output signals of the function generator.

• Ref Clock Source —The source of the reference clock. The function generator derives frequencies and sample rates it uses to generate waveforms from the reference clock.

  Supported Value	Description
  External (1)	The source of the reference clock to be a signal from an external source.
  Internal (0)	The source of the reference clock to be a signal generated internally.
  RTSI Clock (101)	The source of the reference clock to be a signal from the RTSI clock source.

• Arb Sample Rate —The sample rate of the arbitrary waveforms the function generator produces. The units are samples per second. For function generators with more than one channel, this setting affects all channels.
• Internal Trigger Rate —The rate at which the internal trigger source of the function generator produces a trigger, in triggers per second. The Internal Trigger extension supports function generators that can generate output based on an internally generated trigger signal. You can configure the rate at which internal triggers are generated. This setting only affects instrument behavior when the Trigger Source setting is set to Internal Trigger.
• Auto Stop/Start —Automates the stopping and starting of function generation during the Configure operation. When you enable this option, Abort is called before a Configure operation takes place, and Initiate is called at the end of a Configure operation.
• AM Modulation Internal Depth —The extent of modulation the function generator applies to the carrier waveform. This setting affects the behavior of the instrument only when the AM Source setting for a channel is set to AM Internal. The internal depth for modulated waveforms is represented as a percentage.
• AM Modulation Internal Waveform —The waveform of the internal modulating waveform source for AM. This setting only affects the behavior of the instrument when the AM Source setting for a channel is set to AM Internal.

  Supported Value	Description
  DC (6)	A DC waveform as the AM internal modulating waveform source.
  Ramp Down (5)	A negative ramp waveform as the AM internal modulating waveform source.
  Ramp Up (4)	A positive ramp waveform as the AM internal modulating waveform source.
  Sine (1)	A sine waveform as the AM internal modulating waveform source.
  Square (2)	A square waveform as the AM internal modulating waveform source.
  Triangle (3)	A triangle waveform as the AM internal modulating waveform source.

• AM Modulation Internal Frequency —The frequency, in hertz, of the internal modulating waveform source for AM. This setting only affects the behavior of the instrument when the AM Source setting for a channel is set to AM Internal.
• FM Modulation Internal Deviation —The maximum frequency deviation the function generator applies to the carrier waveform. This setting only affects the behavior of the instrument when the FM Source setting for a channel is set to FM Internal.
• FM Modulation Internal Waveform —The waveform of the internal modulating waveform source for FM. This setting only affects the behavior of the instrument when the FM Source setting for a channel is set to FM Internal.

  Supported Value	Description
  DC (6)	A DC waveform as the FM internal modulating waveform source.
  Ramp Down (5)	A negative ramp waveform as the FM internal modulating waveform source.
  Ramp Up (4)	A positive ramp waveform as the FM internal modulating waveform source.
  Sine (1)	A sine waveform as the FM internal modulating waveform source.
  Square (2)	A square waveform as the FM internal modulating waveform source.
  Triangle (3)	A triangle waveform as the FM internal modulating waveform source.

• FM Modulation Internal Frequency —The frequency, in hertz, of the internal modulating waveform source for FM. This setting only affects the behavior of the instrument when the FM Source setting for a channel is set to FM Internal.
