? You can use noise as the modulating waveshape, but you cannot use noise, or dc as the carrier waveform.
? If you select an arbitrary waveform as the modulating waveshape, the waveform is automatically limited to 4K points. Extra waveform points are removed using decimation.
? Front-Panel Operation: After enabling AM, press the Shape
Modulating Waveform Frequency
The function generator will accept an internal or external modulation source for AM.
? Modulating frequency (internal source): 2mHz to 50kHz. The default is 100 Hz.
? Front-Panel Operation: After enabling AM, press the AM Freq softkey, and then use the numeric keyboard or direction keys and knob to input the desired frequency value.

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 10V peak on the output
(into a 50? load).
? If you select the External modulating source, the carrier waveform is modulated with an external waveform.
The modulation depth is controlled by the ±2.5V signal level present on the front-panel Sync/Mod/Trig connector.
For example, if you have set the modulation depth to 100%, then when the modulating signal is at +2.5 volts,
the output will be at the maximum amplitude. When the modulating signal is at -2.5 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.

To Output a Frequency Sweep
In the frequency sweep mode, the function generator “steps” from the start frequency to the stop
frequency at a sweep rate which you specify. You can sweep up or down in frequency, and with
either linear or logarithmic spacing. For this example, you will output a swept sine wave from 1 Hz
to10 Hz. You will not change the other parameters from their default settings: internal sweep trigger,
linear spacing, and 1 second sweep time.

1 Select the function and amplitude for the sweep.
For sweeps, you can select sine, square, ramp, or arbitrary waveforms (pulse, noise, and dc are not
allowed). For this example, select a sine wave with an amplitude of 200 mV.
