    SDG7000A User Manual 11 Dual Channel Setup 11.1 Overview The SDG7000A features enhanced dual channel functionality. With two phase modes, the unit can be used as two independent signal generators, or the two channels can be output synchronously. The ability to track, copy, and couple between the two channels ensures that parameters from one channel are quickly transferred to the other as required, greatly simplifying operation and meeting the need for fast, simultaneous waveform switching.

    SDG7000A User Manual 11.2 Phase Mode The SDG7000A supports two phase modes. Independent mode: Two channels can be used as two independent signal generators, setting one channel does not affect the output of the other channel Locked mode: Synchronous output of both channels, initially phase-aligned and ensuring that they are phase-locked when the frequencies are integer multiples of each other, with no drift In "Independent"...
  • Page 96 SDG7000A User Manual As we can see from the table above, the frequency errors introduced on both channels are small, but not proportional, which results in the two frequencies that were integer multiples no longer being integer multiples, with the result that they are not phase-locked.
