Chapter 3 Features and Functions
Amplitude Modulation (AM)
3
Modulating Waveform Frequency
The function generator will accept an internal or external modulation
source for AM.
• Modulating frequency (internal source): 2 mHz to 20 kHz.
The default is 100 Hz.
• Front-Panel Operation: After enabling AM, press the
AM Freq
softkey.
• Remote Interface Operation:
AM:INTernal:FREQuency {<
frequency
>|MINimum|MAXimum}
Modulation Depth
The modulation depth is expressed as a percentage and represents the
extent of the amplitude variation. At 0% depth, the output amplitude is
half of the selected value. At 100% depth, the output amplitude equals
the selected value.
• Modulation depth: 0% to 120%. The default is 100%.
• Note that even at greater than 100% depth, the function generator
will not exceed ±5V peak on the output (into a 50
Ω
load).
• If you select the External modulating source, the carrier waveform
is modulated with an external waveform. The modulation depth is
controlled by the ±5V signal level present on the rear-panel
Modulation In connector. For example, if you have set the modulation
depth to 100%, then when the modulating signal is at +5 volts,
the output will be at the maximum amplitude. When the modulating
signal is at -5 volts, then the output will be at the minimum amplitude.
• Front-Panel Operation: After enabling AM, press the
AM Depth
softkey. Then use the knob or numeric keypad to enter the depth.
• Remote Interface Operation:
AM:DEPTh {<
depth in percent
>|MINimum|MAXimum}
