Architecture

HD4096 high definition technology consists of

high sample rate 12-bit ADCs, high signal-to-noise

ratio amplifiers and a low-noise system architec-

ture. This technology enables high definition

oscilloscopes to capture and display signals of

up to 1 GHz with high sample rate and 16 times

more resolution than other oscilloscopes.

Oscilloscopes with HD4096 technology have higher resolution

and measurement precision than 8-bit alternatives. The high

sample rate 12-bit ADCs provide high resolution sampling at

up to 2.5 GS/s. The high performance input amplifiers deliver

phenomenal signal fidelity with a 55 dB signal-to-noise ratio

and provide a pristine signal to the ADC to be digitized. The

low-noise signal architecture ensures that nothing interferes

with the captured signal and the oscilloscope displays a

waveform that accurately represents the signals from the

device under test.

12-bits of vertical resolution provides sixteen times more resolution than 8-bits. The 4096 discrete

levels reduce the quantization error. Signals captured with lower resolution oscilloscopes have a higher

level of quantization error resulting in less accurate waveforms on the display. Signals captured on an

oscilloscope with 12-bit HD4096 technology are accurately displayed with minimal quantization error.
