Hi!
The situation in more detail:
The 33500 generates a sinus with 1000Hz. I want to start a sweep (1000->2000Hz in 2s), but I want it to start "in phase" with the current waveform. I don't want it to immediately switch to sweep when I send the SCPI-command. Instead the sweep shall start when the current sinus period is finished (seamless transfer).
Is it possible? How?
Note: arbitrary is not an option since I don't know in advance when the need for the sweep appears...
Many thanks!

Yes the 33500 can do this. When you use the sweep mode of the function generator, and you set the trigger source to BUS. The function generator will sit at the start frequency until you send a *TRG. I believe it will finish it's current cycle and begin sweeping upon receipt of the trigger. There is no disconitinuity I could see when I just tried this out.
Let me know if you have more questions.
