Typical for DX. Product information is very inaccurate or even lie.
I can not understand these manufacturers who accept DX as seller but then they do not care that seller is honest with information. This can only affect negative to manufacturer.
This kind of dropshipper sellers who do not know anything what they sell in boxes. For these sellers it is just same if in box is underwear, a teddy bear or a necklace or oscilloscope.
Example DX tell that TO202 max samplerate is 1GSa/s ~ 5GSa/s.
Also they tell memory is 450M. and also this is in table where they write just TO202
And in specification they write just TO202 (so this is not true mistake)
They use common information for whole product series due to fact that they do not understand nearly anything about what they are selling.
Time ago I buy 100MHz oscilloscope probe from DX.
In my lab test I can characterize this probe as 10MHz probe and quality was most crap what I have never seen. Just total shit. Perhaps collected from some manufacturer junk auction (manufacturers' sales of scrap materials). Right place for these probes was clearly material recycle.
These DX like sellers may very easy give "junk" status for also some good products what are quite unknown and do not have long term strong reputation in markets yet so that junksellers can not affect brand imago.
True information is:
Micsig TO202 have 2 channels, 1GSa/s one channel and 500MSa/s for 2 channels.
Memory (default without memory extension option) 18M / 9M and optinally max 180M/90M
TO504 have max 5GSa/s for one channel and then 2.5MSa/s and finally 1.25MSa/s for all channels simultaneously. Max 450M memory but also this memory is optional. Without option it have 90M one channel, 45M for two channels and 22.5M for all channels simultaneously.
(!)Channels are isolated but this is OPTIONAL
1000V CAT ? 600V CAT ?
and floating between channels also 1000V CAT ? 600V CAT ?
Then also note: 200kwfms/s speed is optional, Serial bus decode is optional. Video/HD trig is optional.
I do not wont ask with dozen letters from DX that what is exactly what get and what not if buy.
Without more information it looks basic 2 channel version without any option.
Also Micsig can do better product introduction sheets and specifications sheets so that it is more easy to find what all features are options, what are options what can activate after sales and what are real factory options what need install in manufacturing phase.
Also I can ask: Why it is so difficult to give perfect accurate full detailed specifications. Tektronix and HP can write these over 50 year ago and still we wait first chinese company who can do this.
There is available totally free study/learning material for this. Just example old Tek and HPO manuals/service manuals. Read carefully these specs. Also big set of old HP journals are free to download and read. Thise may give some image what we want and need in western countries.
In China you can sell chicken in outside markets and buyer is responsible about all things what he buy. He need ask all what he want know before deal and also be enough clever how to get even right weight... without rocks in stomach.
This method can not transfer to overseas T&M equipments sale.
