14-bit ADC delivering four times the resolution
A key component in achieving high vertical accuracy is the ADC. A higher number of ADC bits means more vertical resolution, translating to
more accurate signal representation.
For example, an oscilloscope with a 12-bit ADC can encode an analog input into 4,096 unique levels of conversion (212 = 4,096).
Each additional bit doubles the number of levels of conversion.
Oscilloscopes with a 14-bit ADC can encode the analog input into 16,384 levels (214 = 16,384), which is four times the resolution of oscilloscopes
with a 12-bit ADC and 64 times the resolution of an 8-bit ADC.
Capture smaller signals with a 50 µVRMS noise floor
All electronic devices, including oscilloscopes, generate some level of noise. However, the goal is to minimize the noise as much as possible.
A lower noise floor means that the oscilloscope has less impact on the signal, resulting in more accurate measurements.
The Keysight InfiniiVision HD3 sets a new benchmark in noise floor performance with a 50 µVRMS noise floor at full 1 GHz bandwidth.
You can further reduce the noise with bandwidth limiting and waveform averaging options on the HD3.
Advanced analysis
Automate complex measurements with advanced software capabilities:
- Convert time-domain signals into frequency-domain signals using a fast Fourier transform (FFT).
- Compare signals to pre-defined templates for quick pass / fail analysis with mask testing.
- Analyze the statistical distribution of jitter and noise with waveform and measurement histograms.
- Perform frequency response analysis with Bode plots.
- Isolate signals in seconds with zone touch triggering — simply draw a box with your finger on the screen.
- Characterize signals, hunt for errors, and save them automatically with Fault Hunter.
7-in-1 instrument
More than an oscilloscope, the HD3 helps you save valuable bench space, providing more capabilities in the same footprint
by enabling additional instrument integration:
- Oscilloscope with two or four analog channels
- Mixed-signal oscilloscope to add 16 digital channels
- Protocol analyzer
- Frequency response analyzer
- 100-MHz arbitrary waveform generator
- Three-digit digital voltmeter
- Eight-digit counter with totalizer
