Siglent SDS7000A20 November 2023 - SIGLENT released its new flagship oscilloscope SDS7000A. SDS7000A provides 4 analog channels and 16 digital channels, with bandwidths of 3GHz and 4GHz. The maximum sampling rate is 20GSa/s, the vertical resolution is 12-bit (by hardware), the standard acquisition memory depth is 500 Mpts per channel. This can be upgraded to 1 Gpts/ch. The noise floor is as low as 220╬╝Vrms at 4 GHz bandwidth. The waveform capture rate can go up to 1 million wfm/s, which speed up capturing abnormal events. The Scope has a 15.6-inch high-definition touch screen, which offers much space for analyzing various signals simultaneously and therefore help to improve the developers efficiency.

The sampling rate of 20 GSa/s allows to capture fast signal transitions with high fidelity. Each sample utilizes the 12-bit ADC to limit the quantization error, which can help engineers to observe the details of the waveform clearly and measure the waveform accurately. With the long storage depth of up to 1 Gpts/ch, signal sequences for up to 50 milliseconds at max sampling rate can be captured without any gaps. Utilize search and navigate or history tools make analysis of the entire stored trace easy.

The processor of SDS7000A has been fully upgraded. Utilizing an X86 processor greatly improves the response speed, measurement, operation and analysis speed of the system, and created more opportunities for future expansion of analysis functions.

As the core of signal integrity analysis of high-speed systems, eye diagrams characterize high speed communication signals. The quality of the system can be evaluated by observing the influence of inter-symbol crosstalk, noise, and bandwidth. Jitter analysis characterizes the statistical distribution of small timing changes in a system and is often used to debug digital communication systems and high-speed signal transmission. The SDS7000A series supports automatic parameter measurements for jitter and eye characterization. Easy setup and automatic measurements speed debugging and simplify engineering design testing.

Protocol compliance analysis

With the SDS7000A, SIGLENT provides embedded compliance test solutions to evaluate systems versus communication standards including USB 2.0, 100base-TX, 1000base-T, 100base-T1 and 1000base-T1. Users can flexibly configure the test items, and the software can control the oscilloscope to automatically complete the test, and automatically give the signal test results (Pass/Fail) after comparing with the reference standards. This helps to identify and resolve critical signal and transmission issues quickly.

SAP5000D active differential probe (5GHz)

With the SAP5000D introduced its highest performing active differential probe kit providing up to 5 GHz of bandwidth and low noise for detailed signal analysis. Its high input resistance and low input capacitance can ensure that the load introduced by the measurement system is minimized. SAP5000D active probe utilizes the SAPBus interface, making it suitable for oscilloscopes including the SDS5000X, SDS6000A and SDS7000A series. These probes do not need an additional external power supply and are automatically recognized by the oscilloscope.
