When the modulation depth is greater than 100%, the output amplitude of the instrument will not greater
than 10 Vpp (on-load is 50 Ω.)
It can be change by multifunction rotary knob or press soft key ModDepth, and then use numerical
keyboard to input number and select unit soft key to complete the setting in AM mode.
Comprehensive Example
In AM mode, set an internal 200 Hz sine wave as a modulating signal, another square wave signal with
frequency 10 kHz, amplitude 200 mVpp, duty ratio 45% as the carrier wave and set modulation depth to 80%
at last, the setting steps as follows.
1) Enabling AM Mode
Press ModeShapeAM to turn on AM mode.
2) Set Parameter for Modulation Signal
Base on the step 1, press ModFreq soft key and use numerical keyboard to input 200 and then select the
unit of parameter to Hz.
3) Set Wave and Parameter for Carrier Wave Signal
Press Wave key to enter the carrier wave interface and select square wave to be the carrier wave (the
default is sine wave).
