The Tektronix TDS340A is part of the TDS300 Series Tektronix Digital Real-Time Oscilloscopes. With the TDS300 Series, Tektronix redefines the low-cost digital oscilloscope. No other digital scope offers as much bandwidth and sample rate for the price. By simultaneously sampling at up to five times their bandwidth on both channels, the TDS300 Series assures you of true acquisitions, minimizing aliasing or other digital sampling effects. Unlike other DSOs, the TDS300 Series easily gathers enough samples to display waveforms accurately at their full bandwidth. These are the only scopes in their class to reliably acquire high-speed transient or single-shot events to their full bandwidth.
Many low-cost DSOs offer only dot displays, which can be hard to interpret, especially for those accustomed to analog oscilloscopes. The TDS300 Series has Dot, Dot Accumulate, Vector, and Vector Accumulate displays. The Accumulate display modes gather multiple waveforms for a user-defined time (500 ms to infinity), after which the screen is erased. Vector Accumulate mode uses bright vectors to superimpose the current acquisition over the accumulated waveforms. The display is erased at the user-defined time or when the acquisition setting is changed. These modes are useful for doing worst-case analysis or signal monitoring. Long term monitoring is easily accomplished by setting the erase time to infinity.
