Inside SDS7000A

Think about it.... 
On December 28, 2022, Siglent released two new products: SDS7000A digital oscilloscope and SFA8001 front-end amplifier chip.

SDS7000A is the first 4GHz bandwidth, 12-bit high-resolution digital oscilloscope in China, which raises the domestic high-resolution oscilloscope to a new height and fills the domestic gap in related fields! SFA8001 is the first self-developed oscilloscope front-end amplifier chip with a bandwidth of 8GHz released in China! The chip laid a solid foundation for the research and development of Siglent's 8GHz and subsequent higher bandwidth oscilloscopes.
It is expected that in the near future, a new generation of Siglent digital oscilloscope equipped with self-developed chips will meet with you. At the same time, the development of SFA8001 has also accumulated experience in the development of 16GHz bandwidth amplifier chips.



Siglent's first self-developed chip SFA8001
Amplifier chip: the core of the analog front-end circuit The three core chips inside the digital oscilloscope are: the front-end amplifier chip,
the ADC chip and the digital signal processing chip. Each of these three chips has its own role and has a direct impact on the performance of the oscilloscope.



As the first self-developed oscilloscope front-end amplifier dedicated chip of Siglent, SFA8001 has a high bandwidth of 8GHz and a low noise density of 1.9nV/√Hz, which can help oscilloscopes observe faster and smaller signals.



Self-developed chips: the only way to develop localization
Siglent's chip self-research road is rooted in product design needs, rather than the "muscle show" of corporate strength.
High-bandwidth front-end amplifier chips are difficult to directly implement through board-level circuits, and chipization is an inevitable trend. As one of the three core chips of oscilloscopes, the front-end amplifier chip is different from the ADC chip and the digital signal processing chip, and its application area is narrow and the design requirements are high, so it is difficult to purchase directly in the market.
Not only that, as a dedicated chip, the front-end amplifier chip often needs to be optimized according to the actual oscilloscope design when designing the circuit to better meet the product performance. Therefore, in the field of high-end oscilloscopes, analog front-end chips often exist in the form of self-developed by each oscilloscope manufacturer.



After that the next step is 16GHz...and so on...

The Emperor is far and the sky is high...run your own paths in freedom and fly higher...

Hi Rob,

https://www.eevblog.com/forum/testgear/rigol-hdo1000-and-hdo4000-12bit-oscilloscopes-launched-in-china/msg4708985/#msg4708985

To stop offtopic there...

In my opinion, the gap between the 2000X HD and the 7000A is too wide in terms of offering 12bit scopes for the western market.
I strongly expect the 7000A to cost at least 10000, it is a different league where it will play together with the 12 bit scopes from lecroy and Tek.
There is nothing in between the two extremes.
The 2000X HD is very good, I need to know that for various reasons. 8)
But if you want a bigger screen, for example, or more math channels, as well as increased general performance, but don't want to drop back to 8 bit, you won't find it at Siglent.
I don't know if it's smart to leave the field to other brands in the western market.

Hello,

and "Low noise floor: only 4 μVrms at 220 GHz bandwidth"

I think they mean 220 μVrms at 4 GHz


Best regards
