WaveStation

WSta-OM-E RevA

Press adjacent Operation buttons and use the Digital Input Front Panel

Controls (on page 27) to make specific adjustment/selection parameter

choices. For more information on getting to this point, see Navigating

Interfaces, Adjusting Parameters, and Making Selections (on page 16).

Mod → AM Operation menu selections and parameters include AM Freq,

AM Depth, Type, Shape, and Source as follows:

 AM Freq - This parameter sets the modulating waveform

frequency. The internal source frequency range is 2 MHz to 20

kHz.

 AM Depth - This parameter sets the amplitude range.

Note: Amplitude range is also referred to as amplitude depth or

percentage modulation. It's a percentage value that varies from

1 to 120% . When set to 0%, the output amplitude is

approximately half of the user set amplitude value.When set to

0%, the output amplitude is approximately half of the user set

amplitude value. When set to 100%, the output amplitude

matches the amplitude set. When using an external source, the

AM depth is controlled by the voltage level of the connector

attached to Modulation In on the Back Panel (on page 14). ±6V

corresponds to 100% of your current depth setting.

 Type - Amplitude modulation.

 Shape - Choose the waveform shape type (used as a carrier

waveform) for modulation. Sine, Square, Ramp, or Arb waveforms

may be modulated, while Pulse, Noise, and DC cannot.

 Source - Select Internal or External. If External is selected, use the

Modulation In connector on the Back Panel (on page 14).

Generating a FM (Frequency Modulation)

Modulated Waveform

After selecting the Mod → FM modulated waveform operator button as

explained in the Generating Modulated Waveforms Overview (on page

41), the WaveStation shows the FM Operation menu and corresponding

Display and Detail dialogs.
