The Rigol DS1042C is a 2-channel digital oscilloscope delivering 40 MHz bandwidth and 400 MSa/s real-time sampling for precision signal measurement and analysis. With a 5.7-inch 64K color TFT LCD display, 1M-point memory depth in single-channel mode, and seven trigger types including Edge, Video, Pulse Width, Slope, Pattern, Alternative, and Duration, it captures complex transients reliably. The instrument provides 20 automatic measurements, cursor-based analysis, and math functions (Add, Subtract, Multiply, FFT, Invert) alongside a hardware frequency counter and waveform recorder. Vertical sensitivity spans 2 mV/div to 5 V/div with 8-bit resolution, while the horizontal timebase ranges from 5 ns/div to 50 s/div, enabling both high-speed and low-frequency observation. Input impedance is 1 MΩ ± 2% in parallel with 15 pF ± 3 pF, rated for 400 V (DC+AC peak). The DS1042C stores up to 10 waveforms and 10 setups in BMP and CSV formats via USB Device, RS-232, and USB Host connectivity. Optional MSO module integration adds 16 digital logic analyzer channels, converting the instrument into a mixed-signal platform for embedded system debugging and protocol analysis.
