   With the Tektronix TDS340A 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 TDS340A 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 TDS340A 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.

Oversampling Minimizes Aliasing

   All of the TDS340A scopes sample at five times their bandwidth, assuring users of accurate real-time acquisition up to the full bandwidth of the scope, even for single-shot events. This is well beyond the theoretical two samples per period necessary for a DSO to acquire a true signal. If a DSO cannot sample at least twice as fast as the highest frequency component, aliasing occurs and the scope displays a waveform with a lower frequency than that of the actual input signal. The TDS340A Series' high degree of oversampling not only minimizes aliasing, it also provides a higher resolution waveform.

Acquisition Power

   With edge triggering and basic video triggering as standard features, the TDS340A Series can capture the waveforms that designers and service technicians must see. In addition to 21 automatic waveform measurements, these scopes have four acquisition modes. Sample mode provides real-time sampling at the highest throughput rate. At slower sweep speeds, Peak Detect indicates if there is higher frequency information buried in a waveform, warning the user to increase the sweep speed to avoid aliasing. Envelope mode, by including the highest and lowest points over many acquisitions, shows variations in the signal over time. From several acquisitions, Average mode calculates an average value for each waveform point, reducing apparent noise in repetitive signals.
