The Rigol DS1052E

<< < (68/166) > >>

Counterfeit is probably not the best word, but in my language (Croatian) it translates right...
By counterfeit I mean buy 1052E, modify it, change labels and sell it as genuine 1102E for extra profit.

Yes, you are right on that ;)

My DS1052E seems to have nice knobs and buttons and a good finish, at least on the outside.

If it is a counterfit then I would like this company to make me a $1000 Lexus or BMW please.

First, there is no any kind of mind to make counterfeit RigolD1052E. Not of course. I think you miss now some few points. Also maybe not know what are Chinese inside country markets and peoples living there. I know something, I have be there.

If there is any counterfeit business it ALL need happen there.

Do you know how much money is USD400 example inside China.
Do you know how much these kind of labels cost in China.
Do you know that 1052 is same as 1102
Do you know that scope itself can change model with 15 seconds.

Now if you know this all how to do and also you know how to do all perfect counterfeit things for labelling this scope to different model. Oh... maybe 10RMB...

Next you organize some hundreds or thousends of cheap 1052E go to to change after some buy 1102 example from some asian webstore.

If you get example 1000RMB per unit...

And then you are source to some webstore...

This is not much here in western country... with this money one people can easy live one month in China and I can tell that for this kind of business there you can find very easy million people who want competite who can do this...

Do you know how big business it is example make "genuine" labels for counterfeit batteries... and money in these are just only coins...  there are so many peoples who are ready to make lot of work for get 1RMB. With 2RMB I find tens of peoles who are ready to pickup me with bicycle...  

If this small business for change cheap 1052 to 1102 is possible to somebody without (or just cheap) money and can get part of this money what is price difference between these models... you can be sure somebody have done it or do it all this time.

Who really think make counterfeit oscilloscope... no one.
But buy ready made cheap model and change it to expensive model...

Some people in China only open his window and there rains money in... they are not stupid.
But we... we think that we can check if qenuine by looking serial number... just we talk that mod need sernum change and it takes just second with whatever RS232 terminal (no need PC). Whole type change take not more than 15minutes per unit and this time include also eating, tea and toilet time. After this time normal customer can not know that it was 1052E originally. These cheap labels and papers with scope... how many these you want? Walk an hour around "small" 10million peoples town in right place in China and you have (but be sure that do not try if somebody can quess you are not Chinese)

Easier than alt-010, configure your terminal software to use only LF for newlines (if using the serial port)... I guess some windows software is configured for CR/LF by default?

rf-loop:
Also when you mod... insert RS232 terminal cable before you powON. So you can be sure that buffer have nothing "scratch". And before all, do these right settings for comm parameters. (avoid machines what have not RS232 standard signal levels!)

Remember that in Sysdata displ (R/S red) after *RST it preboot with new "data"... (R/S go green but all is freeze -- do not touch) and....... then powoff/on. also do NOT this mod if Rmt on dspl.

--------


Do NOT try try this modification with RS232 communication if you do not really know how to do this kind of RS232 communication what works perfect. It need work perfect in HW level and it must do without any mistake in data. If you are not really sure how to do reliable trustworth and robust serial connection do not even try. You may seriously damage your oscilloscope. Remember: this use undocumented commands! fail in data may damage your machine nearly as permanently.

Before you do anything with undocumented commands you need (minimum) be sure that communication have no any kind error what may product unwanted transmitted data inside oscilloscope.

Also do not trust Windows/PC RS232 port. It may be out of specifications by many meanings even with voltage levels.
Any missing, extra or wrong data may damage your scope with these undocumented commands.


This is only one small example about RS232 problems with PC and Microsoft:
