As mentioned in other threads.
I have a teardown and some brief review material shot of a new unreleased budget scope that I was going to release today.
But just got an email to HALT all release of material until further notice :(
Some internal company re-positioning thing :-//
I also shot a repair video using the scope, so can't release that one either, not that I had finished the repair anyway, but have a 40min edit.
So left hold my schlong on two videos now >:(
-
That is disappointing Dave, probably something to do with release date that I am told is still a couple of weeks away.
And just when I need more stock. ::)
Some internal company re-positioning thing :-//
Even lower pricing maybe ? :-//
-
Something seems to be going on. I'm waiting with baited breath on the whats and hows of it before buying my first scope, the 'viral' marketing build up seemed to point to it being announced before now. But the telltale EOL discounts have only just kicked in on the older ones. How far ahead is stuff tested/complied? Or maybe its just an inventory thing.
Who knows, couple more weeks won't hurt I guess.

Bet they're going to can the included serial decode.

I do what I want, but I'm not a dick.
The scope was loaned to me in good faith.
-
I do think Dave should hold back.. I just hope they [Siglent, surely?] have a good reason for this, otherwise I fear Dave won't release the videos at all.

What they have killed is my enthusiasm for it. I don't like going back and re-shooting stuff either.

That's pretty unfortunate. The wrong guy found out they were giving serial decode away free, now the entire department is being restructured. :-DD

Hi,
This makes me think that was an attempt to distract from the launch of the Keysight DSOX 1000 series.
Like:
Don't rush and buy the DSOX until you have seen the new xxxx X-E in a couple of weeks.
Then
Oh sorry, the xxxx X-E has been delayed please wait a while longer.
It will be interesting to see how this plays out.

cached copy still up, translation to english is understandable. manuals and datasheet there too
(i finally got fed up of this series of hints and delays. i've "found" the page like two weeks ago. you just needed to search with quotes "sds1000x-e" and use translator/cache to get past automatic redirect. Still, not so interesting in my opinion)

SDS1000X-E - SIGLENT A new generation of entry -level oscilloscopes based on the ZYNQ platform
Modified by junweiz Modified on 01-19-2017 06:18 PM (95 Views)
2017-01-19 Ding Yang Technology
Overview
In November 2016, SIGLENT released a new generation of entry-level oscilloscope SDS1000X-E, its maximum bandwidth of 200 MHz, sampling rate of 1 GSa / s, standard storage depth of 14 M points; it is worth mentioning that, SIGLENT will only before The SPO Super Fluorescent Digital Oscilloscope technology, which is used in high-end series oscilloscopes, is integrated into this entry-level product with a high sensitivity, low-triggering digital triggering system, up to 400,000 frames per second waveform capture rate and 256 levels of brightness level display; the SDS1000X-E also supports a wealth of data acquisition and processing functions, including intelligent triggering, serial bus triggering and decoding, historical mode and sequence mode, rich measurement and math Operations, up to 1M points of the FFT, etc., redefine the entry-level oscilloscope.
Can be some of the high-end digital oscilloscope only with the indicators and functions reflected in the entry-level oscilloscope, thanks to SIGLENT in SDS10 00X-E using Xilinx Zynq-7000 SoC as the core processing chip.

? Figure 1 SDS1000X-E integrated Zynq-7000
The XC7Z020 SoC chip used in the SDS1000X-E has a dual-core ARM Cortex-A9 processor (PS) + Artix-7 architecture based FPGA (PL), where the processor supports up to 866 MHz and the FPGA part 85k logic unit, 4.9 Mb block RAM and 220 DSP slices, and provides support for common external memory such as DDR2 / DDR3, which is very suitable for data acquisition, storage and digital signal processing in digital oscilloscopes . At the same time, Zynq-7000 PS (processor system) and PL (programmable logic) part of the interconnection between the AXI high-speed bus , can effectively solve the traditional digital storage oscilloscope CPU and FPGA data transmission between the bandwidth bottlenecks , Which helps to reduce the dead time of digital oscilloscope and improve the waveform capture rate. Replacing traditional CPU + FPGA discrete solutions with monolithic SoC chips also reduces hardware footprint and facilitates integration of high performance processing systems into compact entry-level oscilloscopes.
Data collection and storage

Figure 2 SPO engine with Zynq-7000 architecture
The high-speed analog-to-digital converter (ADC) chip used in the SDS1000X-E has a data interface of LVDS differential pair, with a rate of 1 Gbps per pair of LVD S. Using the Zynq-7000 chip, the programmable IO LVDS maximum rate of up to 1.25 Gbps, can guarantee a stable and reliable access to the ADC to the data.
At the same time, FPGA received high-speed ADC data needs to be written to the memory in real time, 8-bit, 1 GSa / s ADC, for example, the output data throughput of 1 GByte / s. Zynq-7000 supports commonly used DDR2, DDR3 and other low-cost storage, the highest DDR3 interface rate of up to 1066 MT / s, so the use of single-chip DDR3 to meet the real-time storage of the ADC output data requirements. Moreover, Zynq-7000 supports PL shared PS memory, as long as the PS part of the reserved memory bandwidth, the remaining bandwidth for storing ADC data, no need to re-plug in the PL part of the memory, reducing costs.
More importantly, based on the Zynq-7000's rich programmable logic resources (XK7Z020 for the 85k equivalent logic unit), SDS1000X-E integrated high sensitivity, low jitter, zero temperature drift digital trigger system, making it trigger more For the accurate; all kinds of intelligent trigger functions such as slope, pulse width, video, timeout, rungs, pattern, etc., can help users more accurately isolate the waveform of interest; bus protocol trigger or even directly with the conditions of the bus event (Such as the start of the I2C bus, or UART-specific data) as a trigger condition, greatly facilitate debugging.

Data interaction
With the increase of the complexity of digital oscilloscope design and the improvement of processor processing capacity, the bus structure is becoming the bottleneck of system performance. The traditional entry-level digital oscilloscope, using low-cost embedded processor as the control and processing core, using low-cost FPGA to achieve data acquisition and storage, the two through the parallel local bus interconnection, the processor as a master device , FPGA as a slave device; bus also connected to other processor peripherals, such as F LASH, USB controller, as shown in Figure 4.
(http://mmbiz.qpic.cn/mmbiz_png/XyhJkkdqNzS55oUcY0MG8KdoiaYkDEXWkjkeEVKa6vWaNOdrZHfLxLibIvnqwNwhVo92bN391X7loKh9YqoBFc0Q/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1)
? Figure 4 Traditional architecture of the embedded processor and FPGA interconnection
The biggest problem with this interconnection is that the data throughput is low, first because the local bus is typically an asynchronous bus, ideally a read / write access takes at least 3 cycles (1 setup cycle, 1 access cycle and 1 Hold period). With a 16-bit wide, external bus frequency of 100 MHz local bus, for example, the ideal maximum bus access throughput of 66 MB / s; the second is because the read and write operations share a set of addresses, data bus, ; Third is that multiple slave devices will compete for the bus, thereby reducing the effective data throughput for each slave device. Taking a digital oscilloscope with a sampling rate of 1 GSa / s as an example, the time taken to sample 10 M points is only 10 ms, but the time to transmit 10 M points (at an ideal 66 MB / s bus throughput rate) is at least 150 ms, 15 times the data sampling time. In other words, even if the data processing time is not taken into account, the dead time has reached 15/16 = 93.75%.
The SDS1000X-E adopts the Zynq SoC architecture. The high-speed AXI bus interconnection between the processor (PS) and the FPGA (PL) can effectively solve the bandwidth bottleneck problem of data transmission between the two , greatly improving the data throughput and reducing the number of oscilloscope Dead time. Zynq-7000 used in the four AXI-HP port, each port supports a maximum 64-bit wide, up to 250 MHz clock frequency; while reading and writing channels are separated, can perform full-duplex operation; PS and PL between Point-to-point transmission, there is no bus with other devices to compete. Using a single HP port to transmit data, the throughput rate can easily reach the two-way 1 GB / s speed, 4 ports can achieve a total of read and write rates of more than 8 GB / s, far greater than the local bus transmission rate.
? Figure 5 Zynq SoC in the processor and programmable logic interconnect
Digital signal processing
The SDS1000X-E is equipped with a number of high-performance, powerful digital signal processing functions such as FFT support for 1 M point operation, enhanced resolution (Eres), 14 M full sampling point serial protocol decoding, 14 M full sampling Point of a variety of measurements and mathematical operations, etc., greatly improving the entry-level digital oscilloscope digital signal processing capabilities.
Zynq-7000 rich hardware resources for the SDS1000X-E digital signal processing functions provide a strong support. The XC7Z020 SoC chip used in the SDS1000X-E has a dual-core ARM Cortex-A9 processor with a maximum clock speed of 866 MHz. The parallel coprocessor NEON can perform digital signal processing at the software level. The PL section has 220 DSP slices And 4.9 Mb block RAM; coupled with high throughput between the PS and PL data interfaces, we have the flexibility to configure different hardware resources for different digital signal processing.
Operation instructions are complex, suitable for software implementation functions, can be achieved in the PS side, such as the signal rising edge of the measurement; need to use a large number of cumulative operation, the higher the dependence on hardware resources, can be achieved in the PL side, such as oscilloscope Common interpolation filters.
Some complex functions, you can use the PS and PL between the high data bandwidth for co-processing, such as FFT operations, in the PL side using rich DSP Slice and block RAM resources to build the coprocessor basic FFT operation hardware acceleration, PS Side to achieve a complex window function calculation, drawing, UI and other operations. Based on this co-processing architecture, the FFT on the SDS1000X-E supports up to 1M points of FFT, while achieving very high spectral resolution, but also greatly speed up the refresh rate of the spectrum. Figure 6 shows the spectral resolution comparison at 16 k and 1 M points on SDS 1000X-E, respectively. In this example, we enter a two-tone signal for the oscilloscope with a frequency of 100 MHz and 100.05 MHz. We can not tell two sinusoidal signals so close from the spectrum obtained from the 16 k FFT. The signal is displayed as a frequency And the 1 M-point FFT spectrum has a significantly more detailed spectrum and signal processing gain, from the level of 100 times the expansion of the figure can be seen, two from 50 kHz sinusoidal models can be well separated.

? Figure 6 1M point FFT to obtain very high spectral resolution
Similarly, there are many such high-performance digital signal processing in the SDS1000X-E where many of these PS and PL are co-processed with each other. For example, the SDS1000X-E can perform a variety of measurements and serial protocol decoding of 14 M full sampling points , which are not available in many , mid-range oscilloscopes. Figure 7, the upper two figures for a mainstream midrange oscilloscope on the 10 ns rising edge of the measurement results, the bottom two pictures for the SDS1000X-E on the same signal measurement results. Can be seen in the hour base, the two measurements are more accurate, and the actual rise time difference, but in the big time base, the upper right shows the oscilloscope in 100 us / div can only display "<48ns "Note that at this time its original sampling rate is still 1 GSa / s, which shows that it is not the original measurement of the original waveform data, but after compression mapped to the data on the screen. The lower right shows the measurement result of the S DS1000X-E at 1 ms / div. Note that the sampling rate at this time is also 1 GSa / s, but the measurement accuracy is still 1 ns and can be more truly reflected Signal parameters.
SDS1000X-E digital signal processing based on full sampling points and up to 14 M points of storage depth, allowing users to observe the signal at the same time as a whole at the same time, still can get the details of the processing results; at the same time because of its Zy nq architecture Processing, making the signal processing performance and speed to achieve the best, with better real-time and flexibility.

so at the end of the day, improved decode/math performances?
no more 1.4MS limit for decode (not mentioned in datasheet/manual)?
-
Guess this is what happens when you take free stuff from the evil overlords from BIG SCOPE! ;)
-
Bet they're going to can the included serial decode.
First they've got to make it chooch
Sounds like you've been watching too much AvE (https://www.youtube.com/user/arduinoversusevil)

Moar skookum moar better, but if these chinesium scopes still confuse the serial pixies that's no bueno amigo.
-
They forgot to scratch off the part numbers on the ICs. They have a guy with a counterfeit Dremel tool running around the warehouse, opening the boxes and shaving the chip markings off
-
I'm in the same spot as "bibz" - want to get my first digital scope (a used analog should show up tomorrow to play with) but want to compare all the new ones first. Guess it will be a little longer.
Dave - Thanks for the vids - can't wait for the this one (or two) to come out.
-
So left hold my schlong on two videos now >:(
Please don't get any ideas about doing another video with nerd nudity!
Still wondering what kind of problem causes Siglent to delay an introduction. It must be something really severe like spontaneous self combustion.
-
Like swapped red and black leads? ::) No, I don't want to get banned, please...

I thought maybe they found one on ebay and had to find the source. OK, I know, enough of the Siglent/ebay jokes...
-
Its more of the flakey behavor of Siglent..
-

Yes, that leaves room for some interesting speculation...
Next step, Siglent will officially require Dave to return his sample unit to the dumpster. :popcorn:
-
Do we get a review of the Keysight 1000x?
-
I guess good news anyway for us looking for a new entry level toy?
I hope we get some more info soon
-
Is there an announced (or most probable) date for the official release of the scope?
By the way the previous gen is on offer until March 31st (batronix), so my feeling is that any disclosure of the new product would appear after that date.

They've seen what the the newest R&S scope can do and decided they are way behind the eight ball ;)

Just got an email from them.
They are scrapping the model I have and are beefing up the standard specs. Effect on price unknown, but if it stays the same as I was told it was then the bottom end market just got very interesting.
They said the unit I have is the only one in the world (I presume they mean in the wild).

so they missed the market, with the current device. Sounds pretty dubious to me. Makes me ust wnat to avoid them more.

The scope as it was was quite well positioned, they just wanted to be more aggressive and offer more in a base model.
As always, it will come down to price.
-
Dave, did they give you any rough estimate on the release date? I suppose it will be in 2017 right? Thanks!
-
wondering what's really going on, what they're going to add.. besides the updated processor and the standard decodes
maybe dual adc (or 2GS/s adc)? sample rate was the second most important point that made me cross the sds1000x from my list
also, a local store tweeted about trying the sds1000x-e at embedded world
https://twitter.com/BatterFlySrl/status/841961273696882690/photo/1
so yours wasn't really the only one around... or the sds1000x-e is not the subject of this topic afer all
*audience holds its breath*

"Scrapping" sounds like the ETA is not going to be in the immediate future though. Even if they were working on the new alternative already.
