View Full Version : Best Oscilloscope

08-15-2010, 04:52 PM
I would like to purchase an oscilloscope (PC based or stand alone). Can you experts suggest me one?
Applications: Embedded development on PIC, DSPIC, Arm etc (<100MHz).
Budget: Rs 20,000.00

Thanks in advance

20 k and 100 Mhz is difficult ... also do you really need a osciloscope or a logic analzer. For pricing check this page ... http://www.opencircuits.com/Oscilloscope

I had also bought a high end oscilloscope when i really needed a Logic analyzer.

What would you be using it for , if mostly digital data ... go for logic analyzer.

Thanks for your reply,
I have to analyze I2C signals, Usart signals, Manchester signals, PWM signals etc.

Go for logic analyzer then , a Oscilloscope cannot really do spi with a 2 channel interface ... :)

Some recommends according to price -

http://www.saleae.com/logic/ ( 149 ) ... 24 Mhz
http://www.linkinstruments.com/mso19.htm ( 249 ) ... 60 Mhz
http://www.pctestinstruments.com/ ( 389 ) ... 500 Mhz

All will do SPI , I2C , single wire decoding etc ... explore and buy ...

Pickit is a serial analyzer ( not a logic analyzer ) , also for low speed ... I think max 2.5 Mhz SPI .

If you have the money go for 500 Mhz one , Itll handle everything thrown at it.

I have a Tektronix 2 channel DSO 60Mhz tds1002. I had got it for 50K a few years back. Its really good. I would recommend Tektronix for they are good but expensive. HP agilent are lecroy are better but more expensive. If you can wait I might sell mine for around 25K (may be in couple of months as I am planning to go for higher studies outside India).

The sampling rate for these USB seems to be a bit lower as compared to professionall scope (mine is with 1 Giga samples per second)

Nothing can beat a Tek scope....
They are the back bones of the industry ! sorry that you want to sell it Asimov- lemme see if there's anyone deserving I know wants it.
Maybe I'll junk all my Scopes and buy it myself :P

Hi Docel,
I will let you know before I am leaving.

Nice find avinash

Guys dont u think a logic analyzer is more VFM for digital circuits than a 2 channel DSO.

Thank you for all your suggestions

I purchased DSO 5200 (http://www.hantek.com.cn/english/produce_list.asp?unid=27) from Cochin
200 MHz, 2-Channel
For Rs.19000.00/-

It works fine and is adequate for all embedded related works

Good buy - for that cost- Congrats!!
Please let us know the performance after you use it.

There is a clone for the Saleae Logic analyzer which is based on Cypress chips. Check out this link http://www.nkcelectronics.com/micro-digital-storage-oscilloscopedso-nano.html for a pocket sized dso.

ARM DSO Nano is NOT based on Cypress. Its STM32 ARM Cortex M3 CPU. You can buy it from the Original Manufacture from here (Seeed Studio)

Be sure to pay Custom Duty (Around Rs 1000 extra) and Also get a Import License ( Though I don't do either and use ways to avoid them :) )

But some senior members of RI cares much for legality than the product itself.

A lot of these "on-line" shops are not known to their own Govts. Forget China- they don't follow ANY rules whatsoever and world renowned 'Right to Copy" artists. So, it is imperative that they are 'trust-worthy' or else.....!!


08-28-2010, 07:00 PM
I never said, it was based on Cypress Avinash. I forgot to add the link for the saleae logic analyzer clone. I saw it somewhere one day. I will add the link when i find it. Google for the link. I am sure there will be few links
I have to pay customs @ 23% of the price for development kits. Is that a fair amount.

hi vigyanabikshu,
Good you got a scope and generally 200MHz is more than adequate for embedded system. But my concern is only about its sampling rate 200Mega samples per second this is not sufficient for a 200MHz scope as the Niquist critera for sampling is not fulfilled (which requires twice the sampling rate of the upper max frequency, though the should be adequate for embedded system).

Thats a pretty wrong statement to make- on a public Forum Avinash ! I think it is time that you think twice before you write anything that comes to your mind.

That's a serious comment to make- " cares much for legality than the product itself" - I wonder What you mean by that statement ??

You go ahead and be dis-honest and evade Tax all you want, as you have confessed yourself - but keep off from advertising that fact and advising others on the Forum to do it too.

I can easily delete your arrogant post, but its presence is more harmful to you and so I'm leaving it as-is.
