Another DS1052E thread

- additional persistency settings (0.2s, 0.4s, 0.8s) to what available on Rigol (1s, 2s, 5s, 10s, infinite)

Have those settings been added in the later firmware? As far as I can see, Rigol only has two settings (OFF and Infinite), which kind of sucks.

dude, to be very honest i did remember Rigol has persistency, but wasn't sure about value and qucik checked
the manual. But these values i did posted are for the menu peristency ... that's crap you right, there is only OFF and Infinite.

bah purchased https://www.mortoncontrols.com/index.php?main_page=product_info&products_id=450:09e7c0528bc59445a20d5779a968f174 hopefully i wont regret it

Just looking at what it would take to design what tinhead listed here into the Rigol, my eyeball estimate shows it worth at >= $200.

You can always get more scope for money once the best players in each price range is found, tinhead has been very good showing all of Hantek/Tekway's virtues, and knows the competing products quite well, too.  Tinhead's list is very good, Tekway does perform better as he lists but the Rigol 1052E is not too far off in its basic measurement capability considering its between $150 to $250 less than the Tekway [assuming you pay for S&H at some stores].  It thus, comes down to paying more money for those capabilities.  Lastly, for US buyers, Rigol US supports the scope locally if you buy it locally in the USA; since the USA price is very close to the Chinese overseas price it not cost effective to buy it overseas.  Hantek/ Tekway, does not have a USA rep, IIRC, so your warranty at most is from China.

Hantek lists contact folks, but don't know if they will provide support, if you ever need such:

still thinking about it not sure if the $200 difference is worth it

oh yeah, of course. It is not that Rigol is bad value for money, this is why i wrote "common on both". The bad scopes are definitely all these UNI-T with upscaled pixels on displays but big logo [ 7" Display ] or Owons where only display size matter ... or even the 7" ATTENs where like on Owon or UNI-T only display is big (on paper only) - but that's different story, that's typical marketing dep. reaction to not lose money because of all those Rigols and Hantek/Tekway competitors (don't forget Instek, but they anway good)

 Lastly, for US buyers, Rigol US supports the scope locally if you buy it locally in the USA; since the USA price is very close to the Chinese overseas price it not cost effective to buy it overseas.  Hantek/ Tekway, does not have a USA rep, IIRC, so your warranty at most is from China.

i would not bet on Rigolna support (sry guys but thats the truth about Rigol in NA), all what they can do is to
forward your email to china. The same can be done by mortoncontrols, they located in US and official Hantek partner.
Regards the Hantek "partners" listing, this seems to be very outdated anyway.

bah purchased ... hopefully i wont regret it

hehe don't care, you can still send it back if you don't like it, they have Rigol DSOs too.

so i should get the scope tomorrow.. whats the best way to test it/reviews it? what kind of circuit should i build and then analise?

Rise time & frequency response are the 2 most vital features.  Then for each sampling rate, evaluate distortion and aliasing at its maximum frequency response from subsampling.

so i should get the scope tomorrow.. whats the best way to test it/reviews it? what kind of circuit should i build and then analise?

build a 555 oscillator (relaxation circuit) or pwm or anything oscillating. there are lot of reference here and the net, even for very fast rise time circuit. if you just want to have fun without building any, just find a transformer connected to main and measure its secondary winding, usually found in ac-dc adapter. yesterday i helped my bro to program his 16f876a, it turned out it has not built in osc so i built simple RC osc for it and curious how the osc looks like, then i figured it out in the ds1052e. not to mention the function/arb generator to buy for the fun. just my 2cnts.

[SuperMiguel]

so using my arduino i wanted to create something really fast i wrote this:

Code: [Select]

void setup() {                

  pinMode(13, OUTPUT);    
}

void loop() {
  digitalWrite(13, HIGH);  
asm("nop\n");
  digitalWrite(13, LOW);    
asm("nop\n");

}

and got this:

why is the image distorted like that? is is because of the probes? if yes where can i buy the 200 MHz ones?

[Mechatrommer]

maybe your arduino is doing some extra codes behind at some interval resulting in inconsistent square distance. your scope and probe is not the problem.

[saturation]

Yes, we get better tech support from eevblog  but what I mean is product warranty.  While it looks like Rigol, and even the other lesser brands, do good manufacturing, quality control in China seems to vary like the seasons, and defects of that sort would fall under warranty repairs ... assuming you didn't hack the scope and brick it!

http://www.rigolna.com/warranty/

One should also know, Instek warrants their 1062A for 'life',  at least say 10 years or so given what life means.

i would not bet on Rigolna support (sry guys but thats the truth about Rigol in NA), all what they can do is to
forward your email to china. The same can be done by mortoncontrols, they located in US and official Hantek partner.

I concur with mecha.  Just know Smiguel, that to test your scope, your test gear has to be known >= quality of the scope, or the artifacts you'll see will confuse you, where is it coming from the source, or the test device?
