Micsig new oscilloscopes on website

[skander36]

Clever design with two ADC, where you still have 2 GSa/s with two channels and 1 GSa/s with four channels.

Many 2000 series DSO's have used this design principle for years, even decades, it's nothing new.

It's not new for sure, but rare for chinese scopes. Rigol5K in 2 CH configuration remain with 4 or even 2 GSa/s.

Sounds like a WaveJet from lecroy...
It´s name is program, never heard such a loud scope...

Good to know , although I don't thik I will ever use a Lecroy as a hobbyist.

Not so !

5k AFAIK uses a homespun ASIC, it's different !

SDS2000, SDS2000X, SDS2000X Plus, SDS2000X HD and SDS5000X for all their 4ch models use dual ADC's.
So does the $499 SDS1104X-E.
SDS6000A uses 1 for each channel like many now old scopes did but they never had the memory depth anything like the modern DSO.

Can't offer further info on other Asian brands as may be incorrect.

Older Rigol DS4000 series used 2 ADC too.. GW Instek 2000E series also.

It is actually quite common technique..

We know, skander36 is learning such.

I know you know, I added to your list...   

[skander36]

Is not about that there are two ADC, but that with all four channels activated, you still have half of GSa/s instead of quart.
Anyway the post was more about the noise of this scope. which is annoying.

Indeed, I've checked. Quartation of sampling rate on four channel is more common on Rigol scopes (HDO1k,4K, MSO5K, 7K, 8K) while Siglent has many models that keep sampling at half on four channels.
My intention was to say something good about this scope along with my complain about it, but if the vendor does not come with a solution for noise I think I will return it.
Big difference compared to TO1152 whose noise was barely audible.
Also the battery is draining fast with two fans at full speed all time.

[dmeek]

I use my TO2004 daily and hardly notice the fan noise. Maybe with the TO3004's higher bandwidth, it has a more aggressive cooling system.
I control mine with a wireless mouse, don't use the touch screen much though I have no complaints about it.
In my last post I noted that the scope was not recognizing the probe attenuation factors. After the recent software updatethe BNC X1 X10 sensing
is now working but the Micsig probes are still not recognized. I have a DP750-100 and CP503. I have to set the ranges manually.
The update added a 180 degree screen rotation function so the BNCs would be on the bottom. Of course you have to figure out how to mount it since the
built in stand would be useless.
If anyone else has a TO2004 or TO3004 with Micsig probes, are they recognized on your scope?

[skander36]

I don't have active probes to test, but as you say X10 probes are detected.
I also opened mine to see If I can do something about fan.
Seem to be identical with the 2004.
I don't know what can be improved on the fan, other than finding a better quality one.
I'm afraid to modify speed as in this case the calibration cannot be guaranteed.
It runs quite hot without fans and shields.

[skander36]

Any news on the 500MHz one?

This model is still currently advertised only on Chinese Micsig site and pictures seem to be renderings.
It is available only a flyer  for it and not a user manual so I dont think that it is currently on sale.
But I don't know who will be interested given its propietary inputs MicOpi. This is the only available version, not BNC.

Hi dmeek!
I have aquired DP750-100 and it is recognized and scope show when I change factor from 50 to 500.

Thanks for the info. I'll contact Micsig and see if they have a solution. I don't really want to have to send it back though.

Here are the DC voltages I measure at the interface:

  +4.97V  O  O  +3.31V
  -5.00V   O  O  0V
         0V  O  O  +12.0V
  +3.31V  O  O  -5.94V

@dmeek
The measurements on the scope side are correct.
The same values are on my scope.
Maybe the probe is not ok. Contacts or internals. The leds on it are lighting? Can be manually switched? Relay from Y side cable is clicking?

I have 2 DP750-100, both working but still not communicating with the scope. Contacts are clean, LEDs light, range button works, relay clicks on both.
I've been in contact with Micsig, though no solution yet. While re-testing all my probes I was surprised the find the CP503 is now recognized and 100% working.
So it appears the scope is OK. The mystery continues.

[skander36]

I would make pressure on seller for this. They should exchange probes with the good ones.
Is about a Micsig scope with Micsig probes.
There is no room for tolerance here.

[dmeek]

To follow up on this. I contacted Micsig and they said the probes needed to be re-programmed. They arranged pick-up and paid shipping. I have them back now, working.
I found Micsig responsive and helpful. It was a little bit of trouble but all is OK now.

[Fungus]

Yep. Micsig answer emails very promptly and make an effort to fix things.

(in the two times I've dealt with them, at least, and other people have said the same)

Well, happened to asked one of Micsig's domestic sales, says they are optimizing the TO2004/3004 software and probably a new hardware.

And how can this "probably" help with my problem?

[KlausF]

Micsig performs well, nice



When will Gen 5 with 14" display be released ?
