New series builds on previous 2000X models to bring 200Mpt memory, 10” touch-screen, external mouse/keyboard control, built-in web server, and 50MHz waveform generator

Saelig Company, Inc. has introduced the new Siglent SDS2000X Plus Digital Oscilloscope Series consisting of four models: one 2-channel 100MHz bandwidth (software upgradeable to 350MHz) and three 4-channel models (100/200/350MHz.) The 350MHz models can be upgraded to 500MHz on two independent channels. A large 10.1” capacitive touch-screen supports multi-touch gestures. The oscilloscope range also offers a 10-bit acquisition mode that uses oversampling to achieve higher resolution than most scopes. Combined with the lowest vertical setting of 500μV/div, the X Plus series can display extremely small signal details. The 4-channel models all feature dual 2GSa/s ADCs and also dual 200Mpt memory modules. This enhanced memory depth enables a high sample rate at larger time/div settings. This is valuable when analyzing high-frequency content on slowly changing signals by providing the detail needed, regardless of time-base settings.
The SDS2000X Plus uses the versatile user interface of the higher performance SDS5000X series. This includes the capabilities of a 10” touch-screen, and external mouse/keyboard control.
With waveform capture rates of up to 120,000 wfms/sec, the sequence mode boosts the capture rate to 500,000wfm/s to ensure the capture of critical events and rare signal anomalies. A built-in 50MHz function generator is optionally available together with a free Bode plot function to deliver convenient and low cost frequency analysis. The LAN port supports easy remote control via a built-in webserver using a web-browser or SCPI remote commands.
The X Plus series also features a Power Analysis option for automatic on-screen performance analysis of common power supply characteristics. Siglent’s optional probes for current and differential voltage measurements make a valuable addition for power design applications. When developing switch-mode power supplies (SMPS), Bode plots are a convenient way to measure the phase and gain margin of feedback loop systems to determine the stability of the design. This is now easily performed on the SDS2000X Plus series.
