Tektronix TDS2004C Digital Storage Oscilloscope

The Tektronix TDS2004C is a four-channel digital storage oscilloscope built for signal capture and analysis across benchtop and integrated laboratory environments. Its 5.7-inch color TFT display and 70 MHz bandwidth support real-time waveform acquisition at 1 GS/s with 10X minimum oversampling across all channels simultaneously. The instrument delivers 5.8 ns rise time and 8-bit vertical resolution, enabling accurate characterization of digital and analog signals in development, validation, and troubleshooting workflows.
