Product Description

The QA**0 represents a new milestone in price & performance for *- to **-bit developers working in complex, mixed signal environments at sub *0 MHz speeds. The market today has focused on blindly offering faster and faster oscilloscopes, completely ignoring the challenges posed by mixed signal development. Worse, to achieve the faster speeds at economical prices, manufacturers have dropped to narrower ADC width and in some cases are overclocking ADC parts, further reducing the effective bit depth of the signal to just 6 or 7 bits. Oscilloscopes aren't defined by sampling rate alone. There are a host of variables to take into account. And the right scope for you depends on the types of systems you are working on.
We are mixed-signal developers ourselves. In developing the scope, we knew we wanted wide ADCs from the start. Why is this important when a scope has gain control? Because the width of the ADC determines your dynamic range, or the size of the smallest signal you can see when a large signal is present. For spotting noise in the frequency domain, a **-bit converter can let you resolve noise that is *2 dB lower than an *-bit scope. This is important if you are looking for switching power supply noise on a sensitive analog line, for example. You just can't do this kind of analysis on a sub $**0 benchtop scope.
