I think two channel would be a verry good idea =)

And a better bandwith.

#6

As probably one of the few “audio guys” who want to use this scope in the field when I was not expecting to need one…



It would be nice if the voltage could be interpreted in dBV or dBu with “0dB” being 1V or 0.775V rms. Also as someone posted previously a FFT would be really cool. I think it has also been suggested, but a higher input voltage (even if it is just over-voltage protection) in X1 would also help in a lot of situations.



I fully understand there are limitations to this little DSO - it is useful as it is!



Thanks for making a small and useful product!

How about recording some audio notes while capture the BMP? On DSO quad there will be extra channels, good enough for a microphone. :wink:

:roll: I’ve been using nano V2 as my entry model of DSO and leaning a lot.

well, I sometimes want to observe small voltage drop, ripple or noize in

constant DC 13.8V or 24V. but when I capture those voltage in the display,

I have to set V/Div very big for the drops, like 2-5V/div or bigger, then i can’t

catch small voltage drops in the display. but if I set V/div 20mV/Div for example,

I can’t catch the 13.8V or 24V in the display. I tried changing V/Div setting but

gnd position can only be lowred till bottom of the display.

If I can keep detected value in center or arbitrary position in the display and

change V/div scale into small V/div, that’s be great though.

I don’t have my nano v2 in my hand at the moment though, is this kind of operation

possible since before or in the latest firmware?



thanks in advance for anyone answering.

Have you trid moving the GND on the Y axis as far as you can? This is what you would want maybe <LINK_TEXT text=“http://www.seeedstudio.com/forum/viewto … =12&t=1642”>http://www.seeedstudio.com/forum/viewtopic.php?f=12&t=1642</LINK_TEXT>

Thank you, dnordenberg, yes the topic is exactly what I meant.

I haven’t tried xlm file export yet though, it seems worth to try. but

if we could do it on the nano’s display, that’ll be much easier and

convenient for field engineers, like me.



also, I am thinking that if we could zoom in/out reference wave form

,stored as filexxx.dat, on nano’s display, that’ll be really benefit-able to

analyze wave forms at job site carefully to look any trouble cauing

signals are included or not.

When i tried this on nano V2, the ref. wave form will be gone when I

change v/div, t/div.



Anyway, I maybe telling too much without having any programming knowledge

and source limit. (but it’s because nano is so much attractive tool for me)



thanks anyway,

Multimeter…

#12

I think it would be a good feature to record directly to sd card with adjustable bitrates.

And a more accurate battery indication would be a good idea.

#13

toby- i dont think that would work because of the write speed of the sd card is so slow

#14

Well, it should be able to work with recording every second, should it?

#15

Hi,

A voltage scale (rough indication) on the left side would be nice, preferably with a ‘show on/off’ option in the VD menu.

It will give a quick idea about the gnd level, trigger, etc.

Not sure if this the request for BenF firmware, but anyhow, it would be nice to see “Trigger Holdoff” adjustments. See this vid for explanation:

I second:

  • multimeter
  • show voltages on scale
  • voltage logger by increasing maximum time / div more that 10s. I propose 100s or even 1000s per div.

    There will be for sure time drift but it will perfect fit the need to make measurments over extended time range.
#18

The simplest and most straight forward method is to use a battery as described in my page 2 post of <LINK_TEXT text=“http://www.seeedstudio.com/forum/viewto … 5&start=10”>http://www.seeedstudio.com/forum/viewtopic.php?f=12&t=1655&start=10</LINK_TEXT>.



The battery works best when it is equal to the DC level, or a little above or below the DC level. A simple 9V or 12V battery combination will do.



Remember, if you use a mains connected offset voltage (power supply), make sure that the Nano is not connected to a USB cable during the set up and measurement process to prevent ground loop current flow through the Nano ground lead.

Hi,



I’ve put my wishes on “DSO firmware version 3.61” topic with all details.



In short, two most important are:


  1. To increase refresh screen rate on AUTO. If trigger is not catch, let’s display new waveform immediately, or after some time which user define. The circular buffer has to be used, which always gives the last values in buffer.


  2. Always to sample on 1 MHz (or higher possible freq which CPU allows) and capture three values Average, Min and Max for one buffer value. The Average with 8bit, Min and Max with 4 bit as NONE liner difference to Avg. That will reduce buffer to 2048 size, but it is not such bad as missing hight frequency changes. The Avg value is displayed as before (lines between v(t) and v(t+1)), but below that the vertical line between Min ans Max is displayed with lower color intensity per each t. Or just plot the two pixels (Min and Max). On that way we can see high frequency changes even on high Time/Dev. If it complicate, current Normal/Fast sampling can be only Normal, because we can detect hight freq changes with this option.



    Other, but hard to realize (we can skip this):
#20

Add my vote to:

Definitely a good multi-meter mode with simple, large numbers for volts, frequency

Alluded to already as well, but a good data logger



Now to something new; a range of accessories with supporting profiles on the nano. For instance, a good current clamp with the clamp’s profile (they are generally non-linear) already in the nano. And the on-screen support to show current instead of volts. Other examples: accelerometer, resistance probe, temp sensor. I can see a whole line of “Seeedstudio approved” hardware accessories that I’d be more than happy to shell out money for.



While you are at it, how about thumb drive support for the USB port.

Any possibility of 2nd input via the USB? I know, slow, but possibly used as trigger, or data-logger style input.



That’s it for now. But the possibilities for this little wonder really get the creative juices flowing.

#21

My recuest is this. Im working in my thesis taking lightnig data with an antena and I have to watch the oscope every time that I see a lightning to capture the data.



Is there any way to put the DSOnano in a mode (scan mode like) to automatically empty the buffer every time it gets full and append that data to the end of a certain FILExxx.XML? it would be helpfull if the file auto001.xml have a fixed size and once it reach that size automatically the software creates auto002.xml and it start to append the data to that file. maybe 10Mb.

#22

a jpeg viewer. them we can carry schematic circuits in .jpg format inside SD card.



with a little modification in hardware, we can measure continuity or even resitance. how?



write me. i have the answer…i guess!!!

#23

I fully agree with Wacecs request to prolong the timebase to at least 1000 sec/div for use as a chart recording device. For instance for weather data recording.

#24

- Would be grate to have Other signal types in signal-generator (sine-wave,saw, etc.).


  • As well as Timed Automatic data capture (data-logging<XML) in specified intervals, or on signal change. (every 1/5/10/30/mins || 4khz@5v goes to 2khz@2v )


  • Wave Ghosting(non permanent hold) to work as reference to previous condition of a signal. With variable timing ~ (10ms-5s update interval)


  • And it would be really great if there was a possibility to Record(from probe) and then Transmit(with generator || play file) acquired signal.(in reasonable limits).



    Il be waiting for those features with impatience . Thanks
