Command system EN operates at this frequency, within the frequency limit of this waveform. 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 internal modulation sources (FM:SOURce INTernal) Return format Return as a scientific count.
Example SOURce1:MOD:FM:INTernal:FREQuency 500 /* set the modulated wave frequency of channel 1 to 500Hz */ 3.10.3 SOURce :MOD:FM:INTernal:FUNCtion Command format SOURce :MOD:FM:INTernal:FUNCtion SINusoid|SQUare|RAMP SOURce :MOD:FM:INTernal:FUNCtion? Function description This command selects the shape of the modulated waveform. Argument Instructions This command can only be used for internal modulation sources (FM:SOURce INTernal). Return format SINusoid, SQUare, or RAMP.
For example, SOURce1:MOD:FM:INTernal:FUNCtion SQUare /* Set the waveform shape of Channel 1 modulated wave to square wave */ Copyright © Qingdao Hantek Electronics Co., LTD HDG300C Programming manual 31 Name Range Default value FREQuency 2 mHz to 500 kHz 100Hz Name Range Default value FUNCtion SINusoid|SQUare|RAMP SINusoid
