Hi!
I don't yet have a 33500 but I'm currently looking into it but must first have a couple of questions answered. Hope you people can assist. I'm going for the model with arbitrary functionality and 1MS memory.
I want to generate a sinus with different amplitudes, frequencies, duration etc.
Example: first 10s of 10kHz with amplitude 5V and then 15s of 8kHz with amplitude of 3V and so on.
Will this "eat" up my 1MS memory or is it just somehow sequenced without affecting the available memory for arbitrary signals?
I mean, 10s with 100kS/s (every cycle will be 10 points for a 10kHz sinus) is already 1MS!
How to enter such a signal without using USB stick or manually on the display. I want to download it and then start the generation. Not changing the signal online from a PC after the first 10s and rely on PC-timing.
Many thanks!

Yes the 33500 Can do this if you use the sequencing feature. This allows you to just create 1 cycle of the waveform, then tell it to repeat for the desired count before moving on to the next waveform. This will use a lot less memory since you won't have to waste your memory creating every single cycle. It does require a little more advanced planning since you will have to scale the number of points and amplitudes to get the desired frequencies and voltages. The entire sequence of arbitrary waveforms is played at the same sample rate, so the number of points in the waveform will determine the actual frequency. Likewise the entire sequence is played at the same amplitude, so you have to scale your data accordingly.
The easiest way to create a sequence is with the waveform builder software, it comes with a free 30 day trial, after that the sequencing ability goes away unless you buy it, you'll still be able to create arbs though. I'll create an example sequence next week using the information you provided. Don't have time to do that today, sorry. What I mentioned above will be a little bit easier to understand with an example.
