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.
Remote Interface Operation
AM:INTernal:FREQuency <frequency>
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%.
Soft Front Panel Operation
On the Depth panel as shown in Figure 2- 15, select the
desired modulating depth value from the drop down list.
Remote Interface Operation
AM:DEPTh <depth in percent>
NOTE
At 100% depth, the maximum output of the U2761A will not exceed ±2.5 V
peak (into a 50 Ω load).
