2.4.1.4 AM Rate
Select MOD->AM-> AM Rate, and setthe AM rate.
1. Sine wave modulation frequency range is 0.01Hz~100kHz
2. Square wave modulation frequency range is 0.01Hz~20kHz
2.4.1.5 AM Depth
Set the modulation depth in percent. Select MOD->AM->AM Depth, and then set AM
depth.
When the ―Int‖ modulation source is selected, the AM modulation depth is set from 0.01%
to 100%. The relationship between the modulation depth m and the carrier sideband level
difference ΔP is satisfied: ΔP=6.02-20*log (m)
When the ―Ext‖ modulation source is selected, the sensitivity of the external modulation
source level amplitude to the modulation depth is 50%/V. For example, the modulation
depth is 100% when the external modulation signal is 2Vpp (offset is 0V), and the
modulation depth is 50% when the external modulation signal is 1Vpp (offset is 0V).
When selecting the ―Int+Ext‖ modulation source, the modulation depth set is the internal
source modulation depth + the external source modulation depth, and the internal source
modulation depth is assigned = the external source modulation depth. For example, if the
modulation depth is set to 100%, the modulation depth assigned to the internal source is
50%, the external source modulation depth is 50%, and the external modulation sensitivity
is 25%/V. If the external modulation signal is 2Vpp (the offset is 0V), then the modulation
depth is 100%.
