A portable oscilloscope with a specially designed application-specific integrated circuit (ASIC) that offers half the injected noise and four times the vertical resolution of other general-purpose oscilloscopes can be used for digital debugging. By using an oscilloscope that can view the tiny signals above the noise to detect the smallest and rarest signal faults, you may troubleshoot your design and guarantee product quality.
An analog-to-digital converter (ADC) with a bit size of 14 can increase vertical resolution by four times.
Observe smaller signals with an ultra-low noise floor of 50 µVRMS.
Use a quick 1.3 M waveform/second refresh rate to identify rare signal faults.
Longer time periods can be recorded at full sampling rate using 100 Mpts of deep memory.
Show up to four separate signals simultaneously and manage the scaling separately.
Zone triggering allows you to isolate signals in seconds simply by drawing a box on the screen.
Use Keysight Fault Hunter to automatically describe signals, look for errors, and save findings.
Perform sophisticated analysis using Bode graphs, histograms, and fast Fourier transformations.

PDF DocumentBoth models share a 200 MHz bandwidth, 16 digital channels, 14-bit ADC resolution, and 100 Mpts deep memory. The core distinction lies in analog input capability: the HD302MSO provides 2 analog channels, while the HD304MSO offers 4 analog channels.
The custom ASIC with a 14-bit Analog-to-Digital Converter quadruples vertical resolution compared to standard 8-bit scopes, allowing engineers to view tiny signal variations without being obscured by system noise.
The series operates at an ultra-fast update rate of 1,300,000 waveforms per second (1.3 M wfm/s), making it simple to capture infrequent signal dropouts, glitches, and anomalies quickly.
The instrument supports Keysight Fault Hunter for automated anomaly detection, Zone Triggering via on-screen bounding boxes, Bode plots for frequency response analysis, histograms, and Fast Fourier Transformations (FFT).
The instrument measures 33.5 cm wide, 26.2 cm high, and 16.8 cm deep (13.2 in × 10.3 in × 6.6 in) with a net weight of 5.25 kg (11.6 lbs), making it convenient for both benchtop and field debugging applications.
The oscilloscope delivers an exceptionally quiet noise floor of 50 µVRMS (48 µVrms at 2 mV/div, 1 GHz on a 50 Ω input), enabling high-confidence measurements on ultra-low-amplitude signals.
