Siglent’s latest oscilloscope meets telecoms, wireless demands

Developments in telecommunications, wireless technologies and high speed digital technology are leading to increasing demands for the acquisition and analysis of high frequency and complex signals. This creates an increased demand for oscilloscopes with expanded functionality that can meet the growing needs of modern applications, said Siglent. A high frequency oscilloscope with 12-bit vertical resolution is an essential instrument that not only enables the precise imaging of high frequency signals, but also offers fine differentiation in vertical detection.

Its SDS7000A provides four analogue channels and 16 digital channels, with bandwidths of 3GHz and 4GHz to expand design applications to new test requirements. The maximum sampling rate is 20Gsamples per second, the vertical resolution is 12-bit (by hardware) and the standard acquisition memory depth is 500M points per channel. This can be upgraded to 1G points per channel. The noise floor is as low as 220 microV rms at 4GHz bandwidth. The waveform capture rate can go up to one million per second which accelerates the capture of abnormal events. The SDS7000A has a 15.6-inch high definition touchscreen, which affords space for analysing various signals simultaneously to improve efficiency.
The sampling rate of 20Gsamples per second allows the scope to capture fast signal transitions with high fidelity, said Siglent. Each sample uses the 12-bit ADC to limit the quantisation 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 1Gpoint per channel, signal sequences for up to 50 milliseconds at maximum sampling rate can be captured without any gaps. Search and navigate or history tools help the analysis of the stored trace.

The processor used in the SDS7000A has been fully upgraded. Utilising an X86 processor greatly improves the response speed, measurement, operation and analysis speed of the system. It also creates opportunities for future expansion of analysis functions.

The SDS7000A series supports automatic parameter measurements for jitter and eye characterisation. Easy setup and automatic measurements speed debugging and simplify engineering design testing.

The SDS7000A 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 configure the test items and the software can control the oscilloscope to automatically complete the test, and automatically give the signal test results after comparing with the reference standards. This helps to identify and resolve critical signal and transmission issues quickly, noted Siglent.

The SAP5000D active differential probe kit provides up to 5GHz 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 minimised. The SAP5000D active probe 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 recognised by the oscilloscope.
