U2761A User's Guide
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
the desired modulating frequency value and select the unit
from the drop down list.
Remote Interface Operation
AM:INTernal:FREQuency <frequency>
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
peak (into a 50 Ω load).
Soft Front Panel Operation
