® Set Modulation Wave Frequency
Set the modulation wave frequency in range of 2mHz-200kHz (default to 100Hz). After enabling
AM function, the default modulation wave frequency can be modified by multifunctional knob or
press ModFreg, enter the number by numeric |keypad |and select unit.
® Set Modulation Depth
Modulation depth indicates the extent of amplitude variation which is expressed as percentage.
The range of AM modulation depth is 0%-120% (default to 100%)
® When modulation depth is 0%, constant amplitude is output (half of the set carrier amplitude).
© When modulation depth is 100%, the output amplitude varies with the modulation waveform.
@ When modulation depth is greater than 100%, the output amplitude of the instrument will not
exceed 10Vpp (500 load).
After enabling AM function, the modulation depth can be modified by multi-functional knob or
press | Depth, enter the number by numeric keypad and select unit.
© Comprehensive Example
First run the instrument in amplitude modulation (AM) mode, then set an internal sine wave of
200Hz as the modulation signal and a pulse wave with frequency of 10kHz, amplitude of 200mVpp
and duty ratio of 45% as the carrier wave signal. Finally set modulation depth to be 80%. The
specific steps are as follows:
1) Enable Amplitude Modulation (AM) Function
Press [Mode | — [AM |to enable [AM function.
2) Set Modulation Signal Parameters
After step 1), press |ModFreq/, enter 200, and select the parameter unit | Hz |.
