Command system EN ⚫ To achieve a modulation depth of more than 100%, the output carrier amplitude can be reduced. ⚫ If using AM:SOURce EXTernal, the carrier waveform will be modulated through the external waveform. Return format Return as a scientific count. Example SOURce1:MOD:AM:DEPTh 100 /* Set the modulation depth of channel 1 to 100%*/ 3.2.2 SOURce :MOD:AM:INTernal:FREQuency Command format SOURce :MOD:AM:INTernal:FREQuency |MINimum|MAXimum SOURce :MOD:AM:INTernal:FREQuency? [MINimum|MAXimum] Function description Set the modulation waveform frequency. The waveform selected as the modulation source will operate at that frequency (within the waveform frequency limit).
Argument Instructions ⚫ When selecting an arbitrary waveform as the modulation source, the frequency will change to the frequency of the arbitrary waveform (based on the sampling rate and the number of points in the arbitrary waveform). ⚫ This command can only be used for iternal modulation sources (AM:SOURce INTernal). Return format Return as a scientific count. Example SOURce1:MOD:AM:INTernal:FREQuency 500 /* set the modulated wave frequency of channel 1 to 500Hz */ HDG300C Programming manual Copyright © Qingdao Hantek Electronics Co., LTD 8 Name Range Default value 2 mHz to 500 kHz --
