【TGF4042 signal generator】+ Dual channel comparison test [Copy link]

Dual-channel signal sources naturally need to see the difference between dual-channel and single-channel signal sources. A single-channel signal source outputs only one channel, without a comparison channel, while a dual-channel signal source sets the same frequency signal output with a phase difference of 90 degrees.

Waveforms differ by ninety degrees

When using oscilloscope ch1 as the trigger source, the waveform of ch2 cannot be viewed stably when the frequencies of ch2 and ch1 are different.

Set ch1 to 100K frequency

Set ch2 to 10K frequency

When using the signal source's ch2 as a trigger, the ch2 waveform is displayed stably. The blue waveform in the figure below is the signal source ch1 channel output, and the waveform display is not stable.

When using ch1 and ch2 as xy input, the changes caused by the difference between the waveform frequency and phase can be more intuitively seen
