Analog Modulation
Configuring the LF Output (Option UNT)
Dual–Sine dual–sine waves with individually adjustable frequencies and a percent–of–
peak–amplitude setting for the second tone (available from function generator 1
only)
Swept–Sine a swept–sine wave with adjustable start and stop frequencies, sweep rate, and
sweep trigger settings (available from function generator 1 only)
Triangle triangle wave with adjustable amplitude and frequency
Ramp ramp with adjustable amplitude and frequency
Square square wave with adjustable amplitude and frequency
Noise noise with adjustable amplitude generated as a peak–to–peak value (RMS value is
approximately 80% of the displayed value)
DC direct current with adjustable amplitude
NOTE The LF Out Off On softkey controls the operating state of the LF output. However, when the LF
output source selection is Internal Monitor , you have three ways of controlling the output. You
can use the modulation source (AM, FM, or FM) on/off key, the LF output on/off key, or the
Mod On/Off softkey.
The RF On/Off hardkey does not apply to the LF OUTPUT connector.
To Configure the LF Output with an Internal Modulation Source
In this example, the internal FM modulation is the LF output source.
NOTE Internal modulation ( Internal Monitor ) is the default LF output source.
Configuring the Internal Modulation as the LF Output Source
1. Press Preset .
2. Press the FM/
M hardkey.
3. Press FM Dev > 75 > kHz .
4. Press FM Rate > 10 > kHz .
5. Press FM Off On .
You have set up the FM signal with a rate of 10 kHz and 75 kHz of deviation. The FM annunciator is
activated indicating that you have enabled frequency modulation.
Configuring the Low Frequency Output
1. Press the LF Out hardkey.
2. Press LF Out Amplitude > 3 > Vp .
3. Press LF Out Off On .
You have configured the LF output signal for a 3 volt sine wave (default wave form) output which is
frequency modulated using the
Internal 1 Monitor source selection (default source).
