Modulating Waveform Frequency

The range of the modulating waveform frequency is 2 mHz to 20 kHz. The default modulating waveform frequency is 100 Hz.

Soft Front Panel Operation

On the Mod Frequency panel as shown in Figure 2- 15, input the desired modulating frequency value and select the unit from the drop down list.

Modulation Depth

 

The modulation depth is expressed in 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.

 

The range of the modulation depth is 0% to 100%. The

 

default modulation depth is 100%.

 

At 100% depth, the maximum output of the U2761A will not exceed ±2.5 V

N O TE

peak (into a 50 Ω load).
