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 | |
