Rigol DS1074z vs DS1054z - any difference?
« on: January 27, 2015, 09:13:03 pm »
My distributor is offering to give me a 1074z for the same price as a 1054z?
They don't have any DS1054z's in stock and I already paid for it a couple of weeks ago.

If I have a Rigol DS1074z can I use the same codes to that people are using to 'unlock' the DS1054z?
Is there any difference between the two models? Other than bandwidth.

The 1054z, 1074z and 1104z are all hardware identical correct?

Thanks.

Absolutely identical. Have it before they change their minds.

The 1074z has only one hardware difference, which is the sticker on the front panel.

Monkeh - perhaps you could answer this question.

I have asked this before but haven't seen an answer.

Is the latest firmware for the 1054 00.04.02.07 compatible with the earlier boards?

Should be. Ask Rigol, they should know about their hardware. Let me know if you get the same answer twice..

If they are identical, what difference does it make if they do change their minds?  You would be getting the same thing anyway.

By the way...

If someone can enlighten me.  Any idea (speculation) why they have two identical products with different model number?  Geographic region?  Default power (110/220v)?  Managing more inventory for extra model numbers is not exactly cost free.  They must have a reason....I would hope.

Thanks.

I have  previously purchased DS1074Z for single special purpose  what need  cheap "what ever"  4 channel  (digital)scope when DS1054Z was not available from any known stock.

They are functionally equal.

If you are sure  this 1000Z model serie is for you and you can  get 1074 label on front panel with 1054 price, just take it before it is too late.
EV of course. Cars with smoke exhaust pipes - go to museum. In Finland quite all electric power is made using nuclear, wind, solar and water.

Wises must compel the mad barbarians to stop their crimes against humanity. Where have the (strong)wises gone?

Can you think how much they sell with this marketing trick. They know human psychology.

Produce scope. 100MHz scope.   Model these all with 50, 70 and 100 label.
Then tell how much 70 and 100MHz model price is.
Then take care that 50M model is "hackable" to 100M model,

Peoples feel they get more they pay.

Without marketing trick.
Try make it as one model. Just 100M and nothing else. Also sell it with this price with all options. (no options but all as standard features. And so that nothing is hackable.
Price it just as 50M model now. (sidemark:  using China goverment subsidy and pushing distributors to sell these as "nice boxes" without enough income for real good support/customer care. Now distributors need fund these using income from other models and brands selling.)
Start selling.

Do you think it is still as famous as it is now using this marketing trick.

Accidentally (I think) they fast learn this in near history with DS1000E case.
EV of course. Cars with smoke exhaust pipes - go to museum. In Finland quite all electric power is made using nuclear, wind, solar and water.

No, the engineering model they use to design the hardware is common across all markets. Build the hardware to runs XYZ and charge a suitable price. Oh, you can buy the same hardware that only does X fort a discount and/or unlock the Y and Z for a fee (often more than buying it all up front).
Yes people will pay to get that top of the line badge and know/feel they are doing the right thing or get value for money.
It is not limited to Chinese companies, it is the way of the world. Look at the Flir E4-8 series, although I'm not sure they openly accept the hacking that goes on to make the E4 into an E8 like Rigol appears to for its devices.

As for marketing it is seen as it is in politics... Any publicity is good publicity.
Not easy, not hard, just need to be incentivised.

It's more a production savings and not a marketing ploy, as Dave has stated in one of the threads (I believe it's in the jitter one) they are not really happy with the "upgrades".

Making 3 different boards and associated software will be too costly for them, so they did lump it all together in hopes that customers will play nice.

I somehow doubt the distributor gets the 70MHz model for the same price as the 50MHz model.

They're identical, even the -S versions are the same except they contain a two channel waveform generator.

Ah, I get it.  I did not know that they were sold as different capability (50/70/100mhz).  I thought they were sold without difference in spec.

Even while are hardware identical, I can see the advantage.  They can have lower quality (lower cost) manufacturer do the lower speed one with less quality requirement as cost delta determines.  Higher speed higher price boards may also go through additional QA to ensure proper function at higher speed.  So forth.

I wouldn't call it merely marketing ploy.  They are selling capabilities.  More capability = more $, that's fair.

It's nothing new. I think it was ICL, who manufactured mainframes in the late '60 & '70s, whose base models had a jumper or so which could be removed which doubled the processing speed; for a price of course.

Yeah I know it's an old thread. Just curious what do you get for $200+ when you buy the DS1104Z? I don't see a lot of difference.

thanks

You get 100 MHz input bandwidth. Otherwise no difference in features compared to the 1054Z and 1074Z.

As you have probably gathered from other threads, the bandwidth limitation is firmware-based only. The scopes' hardware is exactly the same across all three models. While Rigol has chosen not to sell bandwidth upgrades as a field upgrade option, one can unlock the 100 MHz bandwidth using a "hacked" key generated by the "RIGLOL" key generator.

I am not convinced that there is no difference.  The hardware is likely the same but Rigol may be grading them or there may be a subtle parts difference.

There was a video last year linked from EEVBlog which showed a transient response test using a reference flat pulse generator on various DSOs including a hacked Rigol DS1054z and it showed a flat 20 nanosecond slope after the rising edge which would indicate a problem like saturation or cutoff in the amplifier chain before the digitizer.  The question would be if the DS1074z displays the same behavior but nobody has tested both under objective conditions.

However for most users of the Rigol DS1000Z series DSOs, if this difference exists it will be irrelevant in typical applications and if it does matter, they should be using a higher bandwidth oscilloscope anyway.

As far as why they have separate models with the same hardware and different firmware based bandwidths, that is all price discrimination.

Also: Cross fingers and hope that:

a) Companies and 'serious' users will pay full price because they worry about guarantees.
b) Hope that others will pay full price because they think there has to be a difference, eg.

I am not convinced that there is no difference.  The hardware is likely the same but Rigol may be grading them or there may be a subtle parts difference.

the difference are the stickers and serial number. that i know of...
about the hack. iirc i read 1074 can be as well upgraded just as the 1054...

IIRC nervous people can go to 70MHz instead of the full 100MHz. You can't be too careful.

I found the video on Youtube.  The Rigol test starts at 16:26.  If I saw that transient response, I would consider the oscilloscope broken or in need of calibration.

I remembered wrong though.  It is an actual MSO1074Z and not a hacked 1054 but that just makes the situation worse.

Yep. The front end has been reverse-engineered and it's 100% clear how the bandwidth is artificially limited in the sub-100MHz models.

(by switching in some capacitors on the input)

Nothing new...  Amdahl had a switch on some of their 470 mainframes that enabled increased throughput.  This allowed the customer to decide when to accept the high rent for higher throughput.  Pay for performance.
