TiePie Engineering HS6 opinions

[ampwizard]

Has anyone had any experience with the TiePie Engineering HS6 differential USB 3.0 oscilloscope? The specs look very good for the price:

 I was wondering if anyone had tried it, verified the specs, and used the software.

Hello,

strange - the most sensible range is only +-200mV.

And 250MHz (150 100 (75(manual) or 50(datasheet))?? MHz) bandwidth with the possible samplingrate?

Perhaps the Picocope 4444 is also interesting.

The skeptic in me thinks this was an advertising post.

Not interested. The price is too inflated.

1G/8b, 500M/12b, 100M/14b, 6.25M/16b look like HMCAD1520 with software averaging 16b mode.
From the datasheet, the so called isolation mode is just implemented with hybrid single ended-differential dividers and the ADC's own diff input capability, with no galvanic isolation, plus some math magic to cancel out divider errors.

Therefore, my estimated BOM cost for this thing is <$230 at small batch quantity ($50 ADC, $20*4 AFE, $50 FPGA+ROM, $10 clock, $20 misc, $20 enclosure).

The software is the most costly part of these kind of products.
Other than that the specs aren't stellar. Assuming 10divisions vertically the minimum sensitivity is 20mV/div and with 47dB (at which frequency?) the CMMR is rather low as well.

Yes, but Chinese scopes with similar Hittite chip sell at $300~$400.

But is the software any good? Software is usually the 'achilles heel' of Chinese test equipment. Cheap but useless = expensive garbage

Hello,

can you give some examples please? I only know some from OWON.
The cheapest XDS3062A cost by Batronix € 470.05

Recent Siglent and Rigol scopes are pretty usable. I have worked with a bare minimum Owon scope that literally has no more features than a CRO besides storage/single and a poorly implemented FFT, and I didn't have much complaint.

That may be but if you buy a scope for more advanced features beyond a CRO and need to get some real work done then non-working and/or crashing software will be a major nuisance.
