I think if Siglent offered a similar four channel 200MHz scope for less than $500 (or even slightly above), they'd obliterated the ciompetition (e.g. DS1104Z)

With serial decoders, etc., included? They'd own the market up to $2000+.

(which is why it won't ever happen)

According to the datasheet, serial decoders are included as standadrd

at a $370 that's a tall order. You'd need another dual channel 1GSPS ADC ($100-$200 itself) and 2 front ends to make a four channel scope.

I think the ADC inside was 4 channel already!?

makes me wonder if this is usable?


The new math co-processor enables FFT analysis of incoming signals
using up to 1M samples per waveform. This provides high frequency
resolution with a fast refresh rate. The FFT function also supports a
variety of window functions so that it can adapt to different spectrum
measurement needs.

Hi, why costs this scope $379.00 in America, and € 434,39 in Europe ?, even while the euro is worth more then a dollar.
Always the same story for many products, i want the same price!, if i order from USA i have no warranty normally.

$379.00 : http://www.saelig.com/product/sds1202x-e.htm
€ 434,39 : http://www.eleshop.nl/siglent-sds1202x-e.html

And howcome its discontinued at this site ?, its a new scope :

That says something right ?

That's the "-S" model.  They don't have the -E, so it offered you that since it's close to your search.

1) You should be aware that most US online shops list prices without tax (AFAIR because taxes are different for every state), while the price in Euro is with taxes. European price without taxes is 359,- €, so nothing to complain here ...
2) your Tequipment-Site lists results for SDS1202x-S, not for SDS1202X-E

Yeah, the US system is way to complicated.  It's usually calculated at checkout.

Each state (and sometimes the county or city) have different rules on how much and if they need to collect it.  When people mention that they ordered online to not pay sales tax, they are technically breaking the law (because you still "have" to pay it).  The general rule is if you have a physical location in the state the store must collect the tax, and if the store does not collect then it's the purchasers responsibility to remit it to the state in their tax payment.  So it depends on where they are and where they are shipping it to on if the store will collect it.

It does.
TQ no longer have distribution rights for Siglent.
I don't know why and don't want to.
Politics I guess.  :-//

Saelig have been doing a good job AFAIK and offer the same discounts for EEVblog members.

PSU looks exactly the same as used in C*L models too and BTW I've not heard of any Siglent DSO PSU failures despite what you always mention of the caps used in Siglent PSU's.  :horse:

Not really sure why Lelon Cap's get such a hard time here and are associated only with entry level 'B' brands. Had no issues with the Lelon Caps in a 13 year old Tek TDS2024. It failed due to a failure with the National Semi ADC.

I've got a busted TDS2012B, a pin on one of the IC's got some contaminant on it and rotted through.  >:(
Kept getting errors on boot and only found a tiny black spot on the pin but it was corroded right through.

As for the Siglent PSU's, they are designed but Siglent but contract manufactured for them.
Mainboards seem to have Nichicon's and the like but despite that the PSU's give zero problems that I know of.

There's been new firmware released:
SDS1202X-E firmware update
Version 5.1.3.13
5.4 Mb

http://www.siglentamerica.com/USA_website_2014/Firmware&Software/SDS1000X-E_5.1.3.13.zip

Changelog
1. Cursor values not correct if probe attenuation was not set to 1X
2. Removed channel input impedance of 50?
3. Added external load setting to FFT menu. If using an external load, amplitudes can be shown in dBm
4. Repaired intermittent lock up after enabling decoding function
5. Optimized translation for German and English menus and pop messages
6. Removed Option label from UI
7. Corrected cursor measurements for active Zoom with FFT
8. Added telnet(port 5024) and open socket(port 5025) for LAN communication
9. Fixed blank zoom bug. With both channels at 2 ms/div, 7 Mpts, and a zoom of 500 ns/div, the zoom window would blank.
10. Fixed decode threshold levels for 10X probe attenuation selection.
11. Fixed average mode. After pressing [Run/Stop] to halt acquisition, the display changed to the last waveform, rather than maintaining the averaged waveform
12. Remain the final message for firmware update until rebooted
13. Fixed the issue with Chinese language setting after self- calibration.
14. Fixed the CAN source bug. If the source selected was CANH or CANL, decode would not work correctly.
15. Decreased waveform jitter with active measurements or math with horizontal delay out of the screen.
16. Added progress information while saving CSV files.
17. Fixed the Cycle RMS measurement does not update when the input signal changes
18. Keep “Print” picture type in accordance with the type selected from “Save/Recall”
19. Fixed user file renaming of a previously saved file.
20. Enabled decoding for time bases above 20ms/div.
21. Disable menu if cursors, measurement and math is disabled
22. Finished updates to support EasyScopeX and Labview driver.
23. Optimized channel self-calibration

Anybody know if a competitor is about to blow them out of the water or if now is a good time to place my order for this scope?

What an impressive scope!
I have waited a few months after Dave's video, but then jumped right in.
It's a very worthwhile replacement for my Siglent SDS1102CML.
