Re: DSO firmware version 3.62

BenF, thanks for v3.62 update. The peek mode gives possibility to he high freq components on fast sample mode. Iygra, the peek mode has no sense for Normal sample mode, i.e Average and Peek are the same for Normal sample mode. Explanation of Avg and Peek mode: Sampling buffer: 5, 6, 7, 6, 0, 1, 2, 1...

Re: DSO firmware version 3.61

Hi guys, First of all I wish to say that I don't like "I'm ... you are ...". If you are all agree with this, please let's avoid this in future. I hope we can all agree for this: - DSO Nano is fine and useful product, but has more limitation then we originally expected for big TD (TD>=5ms). The freq ...

Re: DSO Quad bandwidth

For Bainesbunch: yes, my English is horrible, plus auto correct option => funny sentiences :)

I mean to say that digital filters require more CPU work, so CPU uses more current (power consumption) which reduces battery life.

Re: DSO firmware version 3.61

BenF, if you don't like my suggestions or have no time for them I understand that, but you don't need to shut on me. Your profiling is mostly wrong: I'm programing about 25 years (last 12 professionally), I develop automations, electronic and software for more then 30 machines which customer uses du...

Re: DSO Quad bandwidth

Slimfish: I'm not the Nokia guy. :) I agree with concerns with digital filters. But it is cheaper then fixing the hardware (which is the only real solution). Depending of freq ch., maybe filer could not be so big to make problem with performance, power constipation and additional noise. Also, need t...

Re: DSO firmware version 3.61

BenF: "Fast-mode is likely your best choice for short cycle time and high waveform detail at a T/Div of 5ms. ..." I understand the problem with CPU. That's very bad news, actually it is the worst then I expected. If I understand the algorithm, not only that we have problem with high frequencies on b...

Re: DSO Quad bandwidth

I was planning to order DSO Quad, but I think I will wait until this product become better. One idea based on vernarm's "Wed May 11, 2011 8:52 pm" measurements. It looks like bandwidth could be about 20Mhz (I guess) if seeedstudio correct this by appropriate software digital filter. I guess this is ...

Re: DSO firmware version 3.61

Benf, Just few additional comments and ideas. We need Average, Min and Max values per each t. You can use Average values as replacement for you old samples: for displaying waveform, triggers, saving, ... The Min and Max can be used only for displaying high freq components with lower color intensity....

Re: DSO firmware version 3.61

Hi BenF, I'm commenting "Sat May 07, 2011 2:52 am". First of all, thank you a lot for your time and improvements on this. I'm using DSO Nano occasionally for developing and servicing some machines with analog and digital signals less then 100 kHz. The small size of DSO nano makes it great. I had two...
