I tried to measure a sinus signal at 100 µHz with my R&S RTC1000 oscilloscope (bandwith 300 MHz). The function generator that I used was the EDU33212A. I set the T/div=100s and the oscilloscope shows that it's sample rate was 5samples/sec at the top edge of the screen.

So, the total sample count will be 100s x 12divisions x 5samples/sec = 6000samples.

Do you know why it reduced the sample memory depth so far?

It has a memory capacity of 2 Mpts (2,000,000 samples - in 1-channel mode), so in theory it could capture many more samples. The interpolation mode that the oscilloscopes use was the "sin(x)/x" and for this I believe I saw a smooth sinus signal, with only a small amount of aliasing.

I tried to measure a sinus signal at 100uHz with my R&S®RTC1000 oscilloscope (bandwith 300MHz). The function generator that I used was the EDU33212A. I set the T/div=100s and the oscilloscope at the upper side of the screen show that his sample rate was 5samples/sec. So, the total samples number that he must took will be 100s x 12divisions x 5samples/sec=6000samples. Can you imagine why he drop the samples so down? His memory has capacity of 2Mpts (2.000.000samples - in1channel mode), so in theory he couldn’t take more samples? The interpolation mode that the oscilloscopes use was the “sin(x)/x” and for this I believe I saw a smooth (just a tiny pixeling) sinus signal.
