Siglent SDG1032 Amplitude not constant when sweeping

(1/8) > >>

eTobey:
Is there a way to get a constant amplitude, or just much less?
Sweep goes from 1KHz to 30Mhz.

_Wim_:
Some remarks:
- I see the scope in sampling at 50MS/s, this is too slow for capturing 30MHz (minimum 60MS/s required)
- I presume you are using the 1M input on the scope? Can you give it a try on 50 Ohm input (with a 50 ohm adapter is ok)

Yes, with 50MS/s, the waveform looks rather bad, but its not the form that matters. I have checked with 2Gsa/s, which confirm this issue.

I do not have 50 Ohm, but i set the load option of the gen to HighZ. Should that help?

2N3055:
How many topics will you open?
Will you open individual topic for EVERY SINGLE thing you don't understand and then blame equipment for your lack of knowledge.
Are you going to open a topic per buton per piece equipment you own.
3 topics on same generator so far?

Could you really stop fooling around and learn even the basics.
