Adjusting Parameters of Two Channel Signals (dual-channel model only)
Phase
You are performing a dual-channel test using the arbitrary/function generator, and you want to observe the phase relation-
ship between the CH1 signal and CH2 signal after you change the frequency or period of either channel. The instrument
provides the function called “Align Phase” to adjust the phase relationship between the two signals. Follow these steps:
1. In this example, a 10 MHz continuous
sine waveform is used. Confirm that
both phases are set to 0 degrees.
2. Change the CH1 frequency to 5 MHz,
and then change the CH2 frequency to
5 MHz.
3. To align the phase of two channel
signals, push the Align Phase bezel
button.
When you push the Align Phase
button, the instrument will stop the
signal generation, adjust the phases of
both channels, and automatically restart
the signal generation.
