Just bought one for $328 delivered from Tequipment. Thanks, Dave, for the discount too! Considered the Siglent 1202, but the compensation issue deterred me.

[@Afrotechmods]

This scope looks amazing. Total game changer.

[@rsattahip]

Smart move and long-term planning by Rigol. Even if they don't make a lot of money on these they'll get many new technicians and engineers started using their equipment. Once you buy a first Rigol, you're likely to buy more.

[@markuscwatson]

I just bought one of these!

[@winstonsmith478]

50MHz DS1054Z - $399 100MHz DS1104Z - $830 Quite a price jump.

[@gglovato]

if they would release a 2 channel 100mhz at 399 that would be a winner!. (half the channels half the price). so you can chose, 4 chan at 50 or 2 at 100 same price

[@winstonsmith478]

Yes, that would be a winner. Many don't need four channels. The Hantek DSO5102B 100MHz 2-channel can be found for even less than $399 shipped.

[@h11angel]

or just google 1054z 1104z hack, or browse the EEV blog forum. you'll have quite a surprise :) it's supposed to be upgradeable by software

[@gglovato]

Re pricing on the options is retarded, if you add 2 or 3 of them you go over 1K easily, for SOFTWARE additions -_- i mean, 197$ JUST to enable the memory they purposedly disabled(why not release it with 24mpts and be done with it?, the HW is there!, they could shake the market with that!, but nope...) serial decoding?, 174 advanced trigger(whatever that does its not specified), 191 more! WTH MAN, that's highway robbery For some ~30$ more than the DS1104Z you can go to the DS2072A with 2chans at 70MHz and that one has 500uv/div, it's a shame they didn't make a 2 channel Z model

I have basically no idea what's going on, but somehow it's still interesting and i cant stop watching lol

[@skeezixcodejedi]

swifterik Just lets you observe the voltage of a given connection, and over time; its 'sampling', so taking readings so many thousands/millions of times per second, and giving you a window to scroll back and forth over this value. So you essentially ahve a graph of voltage on the vertical axis, and time on the horizontal. (And many more topions.) You can zoom in to very detailed levels, and set up triggers to capture when certain events occur, etc. If you know software, than an oscilliscope is the debugger for hardware.

[@tubical71]

swifterik jep!

[@EEVblog]

it's like a multimeter that let's you measure voltage. but instead of a digital reading a few times a second it plots the voltage on the vertical axis of a graph, and does that really fast alsong the x axis. this let's you see waveform in a circuit. a waveform is just a fast changing voltage though.

[@dumbo800]

swifterik Your English is fine. I would suggest using the word "on" instead of "at" when referring to days and dates. But it was perfectly understandable.

[@asuspower8629]

swifterik So how was using a scope for the first time? :p Did you enjoy it?

It could be any frequency up to the fastest freq the input bridge rectifier can handle.

[@Tabaskokaffe123]

The engineers are just flexing on how good their ps is 😂

[@KX36]

I have the 1074Z which was the cheapest in the 1000Z series until this came out. I can't recommend it highly enough! This scope really can't be beaten at the low end of the market. The DS1000Z series is the first low end DSO that I've considered to be worth buying for an amateur compared to a second hand CRO. At only £286 inc. VAT in UK from the official distributor Telonic, it's the exact same price as the DS1052E it supersedes. People seem to still be paying that price for Owon or Siglent or GW Instek scopes which are about equivalent to the DS1052E - Crazy.

[@Hexureus]

Hello Dave. I would really love to see you playing around with those resistor/shunts configurations to see what effect would it have on the scope. Could you do an episode on that? Thank you Dave for your great work with the EEVblog.

Now lets wait for the 100mhz hack for maximum value!

[@electrodacus]

Thanks Dave for measuring the power consumption.

[@Agent24Electronics]

Gave up when he got to the PSU - no way I'd buy this. CapXon? Are they serious? When the DS1052E used Nichicon? Talk about a major downgrade... pathetic. I've replaced a lot of CapXon capacitors, mostly in LCD monitors and PC PSUs, because they were all blown! CapXon are absolute garbage and their 105 degree rating is some kind of joke. Then it gets better: the CapXon HP primary - that series has a history of failing (sometimes even shorted) and destroying the hot side of the PSU. No wonder the thing's so cheap! Forget it...

[@44R0Ndin]

'3904's in the signal path of a scope front-end? AND it actually works out to 100Mhz? I certainly wouldn't have called that, but I suppose I shouldn't be that surprised. FM broadcast radio goes from 88-108Mhz, and you can build a perfectly useable FM radio using pretty much a single JFET, a bunch of 2n3904/3906 transistors (around 7 i think?), and a pile of passives. Well, at least it certainly makes finding replacement parts for the front end a bunch easier, if something unfortunate does happen to them.

[@hansi98]

at 25:54 you can see snake-like wires coming out of the front end, is that to keep the lenghts of the channels the same?

[@rgarito]

Yes. It's called "Length Tuning"

[@djdavey163]

Was about to buy a 1052E when I got the notification for this video. I'm not mad, so I have bought the 1054Z instead at the same price. Thanks Dave, just in time :)

[@redtails]

At 399 it's a pretty nice scope. I browsed around a bit around European webshops and (well apart from the fact they're all not in stock), the prices have HUGE differences in them. I saw them as low as €360 and as high at €699 for the exact same scope with the same accessories. Definitely pays off to look around before you purchase this oscilloscope in Europe.

[@jebsaekam]

EEVblog @20:45 ish There is mention of the 2000 series frontend and the 1052e frontend, but overlay of those pictures. Perhaps an oversight?

The bird may be a common chaffinch or an eurasian bullfinch, a thin one, at that. Thank you very much for this teardown video. Maybe the dig potentiometers and the quad opamp placed on the same layer are for the trigger... I was thinking to buy one and modify it at will for some personal extended functionalities. The cost is the reason why this one instead of a big 2GHz/40GSps! BTW, what do you think of the DS1074Z, so a bit more bandwidth and above all the logic analyzer part? Is it worth the difference of price, quite huge gap from my point of view?

It is 300 euro more for the DS1074Z-S, so 300 euros more for a built-in function generator and 70Mhz. Is that worth the money? Rigol cheapest function generator cost about 300 euros. What do you think?

After watching a few videos about oscilloscopes, I'm wondering why the development of oscilloscopes is so slowly. E.g. the Rigol DS1054Z is still sold for at least 6 years until today in the year 2020. Smartphones are technically old when they get 5 years. Why isn't it the same with oscilloscopes?

[@sciencedirect6424]

Thanks Dave This is Good Review, by the way does any one know is it possible to hack DS1000Z (1054Z /1074Z / 1104Z)series to Higher bandwidth as like as DS1052E ? please inform the complete way or post a link

[@teardowndan5364]

The code generator for the DS1000Z (non-MSO, non-S) has been out for something like a year and the DS1054Z uses the same codes. The analog front-end has over 120MHz of input bandwidth, which means you cannot trust this scope for accurate waveforms when using three or four channels if your input may have content beyond fs/2 due to sampling aliasing.

[@seamonkeys12y]

Those Chinese characters seem to represent the colour of the wire. I recognise some of the colours since I know a bit of Japanese

[@acjbigpond]

Is the DS1054Z still the best entry level scope in 2021?

ARM9 at 454Mhz?, that's not a beast, that's 2003 vintage obsolete CPU architecture(ARM v5), try OLDER than "iphone 1"(which is armv6) vintage.... not even dual core!. For example the i.mx31 has a ARM11 core, this is even smaller! The minimum acceptable for this nowadays would be a Dual ARM cortex-A9 (Armv7) which would give an order of magnitude boost(more than twice the IPC per core, more than twice the clock), like the freescale i.mx6 dual!(albeit it costs 28$ in 1000u vs 7 for the shit imx28)

The Agilent 54622D had similar display performance to this scope and ran on a 14MHz 68HC12. All the "hard" display work in these types of scopes is done in the FPGA/ASIC.

minimum acceptable? I don't know where you got that idea from, but in large qty. consumer product scenario, whatever meets the spec at the lowest price is the one you go with (especially when they're all readily available). And as others pointed out, considering all the hard work is done by the FPGA/ASIC and this processor would mostly be dealing with the UI, For this purpose, this proc. is indeed a beast/overkill to some degree.

I must ask about temperuters, you guys who are happy enough too live in warmer than me who lives in Sweden. My small little hobby shed is placed in my basement which isn't heated during wintertime, how does these DSO coop with temperature variations? In the summertime it's about 10-15 degrees and in the winter it can drop below 0 degrees...

I think they use the resistors to enable/disable the logic analyzer and the signal generator functionality. Would be cool to mod it some way to add signal generator functionality. Any DS1000Z-S teardown?

I'm dissapointed about the Crapxon capacitors, but I suppose to get that nice price you have to make sacrifices. Well, at least I have a lot of experience changing Capxon capacitors.

[@excavatoree]

In another reply to a similar comment, Dave mentions that Rigol have no doubt done the proper engineering to use the capacitors properly. In the monitors I repair, that is obviously not the case. However, even they lasted a while. Time will tell.

[@teardowndan5364]

The main reason capacitors fail is because they are under-spec'd. With the number of CapXon caps in the output filters and the meager 20-25W power draw including power supply losses, I seriously doubt those caps have enough AC current ripple on them or heat around them to kill them any time soon. CapXon might only last a year or two in a 300-400W PC PSU but in a 30W PSU with so many caps presumably in parallel, I would not be surprised if it lasted 10+ years.

[@EEVblog]

Daniel Sauvageau That would be my guess too, likely not a problem. Rigol would know this and would care.
