New Keysight InfiniiVision HD3 oscilloscopes

With the new Keysight HD3 oscilloscopes, you can measure what has been hidden from you. We bring you features that were previously unthinkable in mid-range oscilloscopes:

• Unique vertical resolution with 14-bit A/D converters
• See even the smallest signals with a noise level of only 50 µVRMS
• You won't miss any signal changes thanks to the 1.3 million waveforms/second measurement speed at any oscilloscope setting
• Record long periods of signal with memory up to 100 million points/channel
• Keysight Fault Hunter to automatically find errors and anomalies in the measured signal
• Advanced tools for analysis of the measured signal such as FFT, histograms or frequency response analysis (Bode plot)

Unrivalled vertical resolution
A key component in achieving high vertical accuracy is the AD converter. 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.

See even the smallest signals with a noise level of only 50 µVRMS
All electronic devices, including oscilloscopes, generate some level of noise. It is important to suppress this noise as much as possible. A lower noise level means that the oscilloscope is able to accurately measure even very small signals. The Keysight InfiniiVision HD3 oscilloscopes have a noise level of only 50 µVRMS at 1 GHz bandwidth. This noise level can be further suppressed by bandwidth limiting or averaging the measured signal.

Advanced analysis options
With Keysight HD3 oscilloscopes, you can not only measure the signals, but also analyse them in detail with a wide range of tools:

• Convert time-domain signals into frequency-domain signals using a fast Fourier transformation (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
• Automatic search for user-defined phenomena, errors or anomalies in the signal using the Fault Hunter tool

7-in-1 instrument
The Keysight HD3 is not just an oscilloscope, it's actually up to 7 different instruments in one:

• Oscilloscope with 2 or 4 channels
• Logic analyzer with 16 digital channels
• Protocol analyzer
• Frequency response analyzer
• 100 MHz function/arb generator
• Digital voltmeter
• 8 digit counter with totalizer

How to build your own Keysight HD3 oscilloscope?

1. Select the base model according to number of input channels needed

• HD302MSO 2 channels, 200 MHz bandwidth, 20 Mpoints memory
• HD304MSO 4 channels, 200 MHz bandwidth, 20 Mpoints memory

Included with each oscilloscope are N2843A 500 MHz, 10:1, 11 pF passive probes in numbers corresponding to the number of analog channels of the oscilloscope.

2. If you need higher frequency range than 200 MHz, select one of following options

For 2 channel model HD302MSO:

• HD3BW-001 350 MHz bandwidth
• HD3BW-002 500 MHz bandwidth
• HD3BW-003 1 GHz bandwidth

For 4 channel model HD304MSO:

• HD3BW-007 350 MHz bandwidth
• HD3BW-008 500 MHz bandwidth
• HD3BW-009 1 GHz bandwidth

3. If you need longer memory than 20 Mpoints/channel, select one of following options

For all Keysight HD3 oscilloscopes purchased until 31.12.2024 we provide free memory option of 100 Mpoints/channel  (HD3MEM-100)!

• HD3MEM-050 memory 50 Mpoints/channel
• HD3MEM-100 memory 100 Mpoints/channel

4. If you need analysis of serial buses, select from following sw bundles

• HD300EMBA I2C, SPI, UART (RS232/422/485) analysis
• HD300AUTA CAN, CAN FD, CAN XL, LIN analysis

5. Other accessories and extensions

• HD3MSO probe for16channel internal logic analyzer
• HD3WAVEGEN 100 MHz functionarb generator
• HD3COVER front panel cover
• HD3CASE soft carrying case
• HD3RACK rack mount kit

You can upgrade oscilloscope bandwidth, memory depth, serial bus analysis or an internal 100 MHz generator at any time by purchasing the appropriate software license.
