Siglent SDS1204X-E Oscilloscope User Manual

The Siglent SDS1204X-E offers a 200 MHz bandwidth across all four analog channels with a maximum real-time sample rate of 1 GSa/s. The 1 GSa/s rate applies when using one or two channels; when all four channels are active, the sample rate is 500 MSa/s per channel. This makes it suitable for characterizing digital signals and moderately fast analog circuits.

The SDS1204X-E is a four-channel oscilloscope, meaning it can simultaneously display and measure four analog input signals. This is the maximum channel count in Siglent's SDS1000X-E series, which also includes two-channel models like the SDS1102X-E and SDS1202X-E. The four channels share the 1 GSa/s sampling architecture.

Yes, the SDS1204X-E includes built-in serial decode for protocols such as I2C, SPI, UART/RS-232, CAN, and LIN as standard features. Decoded data is displayed directly on the waveform in both bus and list formats. The scope also includes a 16-channel digital mixed-signal option for logic analysis when the SAG1021 or equivalent module is connected.

Yes, the SDS1204X-E features a 7-inch TFT color touchscreen display with 800 × 480 resolution. Siglent markets this as a SuperPhosphor display, capable of showing up to 14 levels of intensity grading to represent signal frequency of occurrence. The touchscreen supports waveform zooming, cursor placement, and menu navigation.
