Key Specifications: UNI-T MSO3304X vs Keysight 4000X

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.
