The Tektronix TDS7404 is a 4-channel digital phosphor oscilloscope engineered for high-speed signal acquisition and characterization. With 4 GHz bandwidth and 20 GS/s real-time sampling, it captures fast transient events with exceptional temporal resolution. The instrument delivers over 400,000 waveforms per second through DPX acquisition technology, enabling rapid fault detection and statistical signal analysis. Deep memory to 32 Megasamples supports extended capture windows, while jitter measurements down to 1 psRMS enable precision timing analysis critical for serial data and clock recovery applications.
