Separate signal from noise

Perform digital debugging using a portable oscilloscope with a custom application-specific integrated circuit (ASIC) that delivers four times more vertical resolution and half the injected noise of other general-purpose oscilloscopes. Troubleshoot your design and ensure product quality by debugging with an oscilloscope that can see the small signals beyond the noise to catch the slightest and most infrequent signal glitches.

Increase vertical resolution by four times with a 14-bit analog-to-digital converter (ADC).
See smaller signals with a 50 µV_RMSnoise floor.
Find signal glitches with an uncompromised 1.3 M waveform / second update rate.
Capture longer time spans at full sample rate with 100 Mpts of deep memory.

Display up to four independent signals and control the scaling individually.
Isolate signals in seconds with zone triggering — simply draw a box on the screen.
Characterize signals, hunt for errors, and save automatically with Keysight Fault Hunter.
Perform advanced analysis with fast Fourier transforms, histograms, and Bode plots.

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 µV_RMS 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

Probes for every application

Start today with the probes that come standard with the HD3 oscilloscope:

Discover the Keysight N2843A passive probe that offers 500 MHz bandwidth, a 10:1 attenuation ratio, and a high input resistance of 10 MΩ (standard one per channel).
Explore the mixed-signal oscilloscope (MSO) capability that comes standard on the HD3. If you already use one of Keysight’s 16-digital channel MSO cables, simply plug it in.

Need additional functionality? Keysight offers a broad range of voltage, current, and optical probing solutions for oscilloscopes.
