Tektronix TDS540D 500MHz, 4 Ch, 2GS/s, Digital Oscilloscope

The Tektronix TDS540D is a 500 MHz, 4-channel digital oscilloscope built on Digital Phosphor Oscilloscope (DPO) technology for advanced electronic design and debug work. It captures and displays amplitude, time, and amplitude distribution data simultaneously, revealing signal dynamics including transient events and occurrence frequency. The instrument samples at 2 GS/s across 50 kPts of standard record length per channel, with optional expansion to 8M points. An intuitive graphical interface with dedicated controls and online help streamlines operation and measurement workflow.
