HD4096 HIGH DEFINITION TECHNOLOGY
HD4096 high definition technology consists of high
sample rate 12-bit ADCs, high signal-to-noise ratio
amplifiers and a low-noise system architecture. 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.

16x More Resolution
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.
