Siglent has launched a flagship oscilloscope with 4 analog and 16 digital channels and bandwidth up to 4GHz.

The Siglent SDS7000A has a 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 220μVrms at 4 GHz bandwidth and the waveform capture rate can go up to 1 million wfm/s, which speed up capturing abnormal events.

The SDS7000A has a 15.6-inch high-definition touch screen for analyzing signals simultaneously and helping to improve the developers efficiency.

The sampling rate of 20 GSa/s allows to capture fast signal transitions with high fidelity using the 12bit ADC to limit the quantization error. This helps 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.

The processor of SDS7000A has been fully upgraded with an X86 processor 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 with easy setup and automatic measurements to speed debugging and simplify engineering design testing.

Siglent also 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.

The oscilloscope is supported by the SAP5000D 5GHz active differential probe for detailed signal analysis. Its high input resistance and low input capacitance can ensure that the load introduced by the measurement system is minimized. This uses the SAPBus interface, making it suitable for oscilloscopes including the SDS5000X, SDS6000A and SDS7000A series.

The probes do not need an additional external power supply and are automatically recognized by the oscilloscope.
