Default Bitscope, a marvellous device.

In response to this https://www.vintage-radio.net/forum/...d.php?t=178726 thread, and not wanting to hijack it I put forward the delights of the Bitscope Micro http://www.bitscope.com/product/BS05/ . At about a ton (100) a lovely thing for the desktop when the workshop is a bit too far away. Good for portable use too, OK it isn't the best 'scope, logic analyser or signal generator out there, but it is in one small package and with quite useable software.

I have one at work (OK I bought two, one is at work!) great tinkering thing.

That's one I hadn't seen before.

For just a 24MSPS 8ch Logic Analyser protocol decoder, then there's been some very cheap ones, like these:

Although boards to send SPI/I2C are slightly more and GUI software may be lacking on cheapest FTDI MPSSE & Bus Pirate etc. ones (but significantly cheaper than the quite popular Total Phase Aardvark etc.)

And multi-instrument in one types are often quite a bit more.
These Discovery ones, with 100MSPS sampling are around twice the bitscope price for just Digital inputs. But do seem quite good, apart from not being very open with their design, to allow you to write all your own software.
And ones with Analogue inputs are quite a bit more:

Default Re: Bitscope, a marvellous device.

From a list of all the Bitscope models: http://my.bitscope.com/store/?p=list&a=list&i=cat+0
I later discovered there's also a larger BS10 100MHz 10ch one, but around 180 direct / doesn't seem stocked by UK distributors. And still only 40MSPS, so not as high as 100MSPS Digilent Discovery.


However the smallest Bitscope Micro BS05(U=bare unit / P=with dual BNC breakout board), whilst being 110 / 125 direct and from some UK distributors was listed from 70 at Pimoroni (although out of stock).

But Farnell / CPC sell the Bitscope micro BS05(U/P) even cheaper, with for some reason the BS05P package (with dual BNC breakout board) actually several pounds cheaper than just the BS05U unit! - Farnell are selling both for < 50 inc. VAT

And CPC sell the Bitscope Micro BS05P for just under 40 inc. VAT (free delivery on orders over 17.50+VAT)
https://cpc.farnell.com/bitscope/bs0..._PFProdSubstit

Although most currently out of stock, but backorders available in next few weeks for their actually lower-priced BS05P package.

I did note some mixed reviews on Farnell / CPC, where it seems they drop down from 10bit to 8bit resolution at higher speeds, so a bit noisy. And there maybe some issues with latest version of Windows 10 and their software not being updated for last 5years.

Plus, the free open-source sigroc software doesn't support the BS05, although they do list plans to support the BS10: https://sigrok.org/wiki/Supported_hardware


There are also some similarly spec'd USB 2Ch 'scope-only units, for around 50 as well - but supplied with probes - from here etc.: https://www.banggood.com/Hantek-6022...r_warehouse=CN
- But only 8bit, and not sure how good their software / support etc. would be
