Detailed Feature Comparison: UNI-T MSO3304X vs Keysight 4000X
Superior Memory Depth
The MSO3304X features an impressive 500 Mpts memory depth, which is 125 times more than the Keysight 4000X Series with its 4 Mpts. This exceptional memory depth allows you to capture longer signal sequences at high sample rates, critical for analyzing complex behaviors in modern electronic designs. Identify intermittent glitches and rare events that would be missed with lower memory oscilloscopes.
Unmatched Waveform Capture Rate
With an industry-leading waveform capture rate of up to 2,000,000 waveforms per second in sequence mode, the MSO3304X offers twice the performance of the Keysight 4000X Series (1,000,000 wfms/s). This superior capture rate dramatically increases the probability of catching elusive and intermittent events that occur randomly or infrequently, making debugging faster and more efficient.
Advanced Display Technology
The MSO3304X features Ultra Phosphor 3.0 technology with 256 temperature levels, providing exceptional signal detail and visualization. While the Keysight 4000X offers a slightly larger 12.1" display, the UNI-T's 10.1" high-resolution display with Ultra Phosphor technology delivers superior signal visibility and detail, making it easier to identify subtle signal variations and anomalies.
Superior AWG Capability
The MSO3304X includes a dual-channel 50 MHz Arbitrary Waveform Generator with our free Ultimate Options Bundle, compared to Keysight's optional 20 MHz dual-channel AWG that requires an additional paid upgrade. This higher bandwidth AWG allows for more sophisticated stimulus testing and signal generation for a wider range of applications.
Industry-Leading Warranty
Register your MSO3304X online and receive a 5-year warranty at no additional cost, compared to Keysight's standard 3-year warranty. This demonstrates our confidence in the MSO3304X's quality and reliability, and provides you with long-term investment protection and peace of mind.
All-in-One Value
The MSO3304X integrates 9 instruments into one compact package: oscilloscope, logic analyzer, dual-channel AWG, spectrum analyzer, digital voltmeter, frequency counter, protocol analyzer, bode plot analyzer, and power analyzer. This comprehensive functionality saves valuable bench space and eliminates the need to purchase multiple separate instruments.

Frequently Asked Questions: UNI-T MSO3304X vs Keysight 4000X
How does the MSO3304X compare to the Keysight InfiniiVision 4000X Series?
The MSO3304X offers 125X more memory depth (500Mpts vs 4Mpts), twice the waveform capture rate in sequence mode (2,000,000 wfms/s vs 1,000,000 wfms/s), and includes all software options at no extra cost, while providing equivalent bandwidth and sampling rate. The MSO3304X delivers superior value with its comprehensive feature set at less than half the price of comparable Keysight models.
What makes the 500Mpts memory depth so important?
Memory depth determines how long you can capture signals at high sample rates. With 500Mpts - 125X more than Keysight's 4Mpts - the MSO3304X allows you to record much longer signal sequences while maintaining full resolution. This is critical for capturing and analyzing complex behaviors that occur over extended time periods, such as startup sequences, intermittent glitches, or serial bus communications with long idle periods.
How does the Ultra Phosphor 3.0 technology enhance signal visualization?
The MSO3304X features Ultra Phosphor 3.0 technology with 256 temperature levels, providing exceptional signal detail and making it easier to identify rare events and signal anomalies. This advanced display technology, combined with the high waveform update rate, allows you to see subtle signal variations and intermittent glitches that would be missed by conventional oscilloscopes.
