Description
Duty Cycle
Sets the duty cycle of the square wave using the keypad or multipurpose knob.
Available when the Waveform Type = Square.
Frequency
Sets the frequency of the waveform using the keypad or multipurpose knob. The frequency range is
0.1 Hz to 50 MHz, in increments of 0.1 Hz.
Period
Sets the period of the waveform using the keypad or multipurpose knob.
Amplitude
Sets the amplitude of the waveform using the keypad or multipurpose knob.
Offset
Sets the offset of the waveform using the keypad or multipurpose knob.
High Level
Sets the High signal amplitude of the waveform using the keypad or multipurpose knob.
Low Level
Sets the low signal amplitude of the waveform using the keypad or multipurpose knob.
Load Impedance
Selects either 50 Ω or High Z (1 MΩ) output load impedance.
Load impedance scales the vertical settings to show what the load would see based on the load
impedance. Since the AFG is a 50 Ω source, for most accurate operation, set the load impedance to
50 Ω and set the input channel to 50 Ω.
Add Noise
Toggles noise on and off. Set the amount of noise to add to the output signal using the keypad or the
multipurpose controls.
When Modulation is on, Add Noise is not available.
OK, Load Waveform
Loads the selected waveform.
Browse
Browse to the desired waveform.
Save Waveform
Opens a Save As menu for saving AFG waveforms to internal waveform slots or to an external file
location.
Modulation menu fields and controls
Note: The modulation menu is not available when the Waveform Type is set to DC, Pulse, Noise, or Cardiac.
