Tektronix MSO4000 and MSO4000B Series Mixed Signal Oscilloscopes
4 models with full specifications from Tektronix.
The Tektronix MSO4000 and MSO4000B series mixed signal oscilloscopes are built for testing and debugging complex embedded systems. Combining four analog channels with 16 integrated digital channels, these instruments serve as both an oscilloscope and a logic analyzer. This page covers the core differences across the family, including models with bandwidths ranging from 350 MHz up to 1 GHz. It is intended for hardware engineers and laboratory technical buyers comparing the capabilities of the original MSO4000 series with the expanded specifications of the MSO4000B series.

Bandwidth and Sample Rate Scaling
The models within this family are scaled primarily by their analog bandwidth capabilities. The base model MSO4034 offers a 350 MHz bandwidth with a typical rise time of 1 ns. For mid-range measurement needs, the MSO4054 provides a 500 MHz bandwidth and a 700 ps rise time, coupled with a 2.5 GS/s real-time sample rate.
At the top end of the family, the MSO4104 and the MSO4104B provide 1 GHz of analog bandwidth. These 1 GHz models deliver a real-time sample rate of 5 GS/s across all analog channels. The MSO4104B features a typical rise time of 350 ps.
Record Length and Acquisition Differences
Memory depth determines how much signal detail can be captured over extended timeframes. The standard MSO4000 models—the MSO4034, MSO4054, and MSO4104—feature a maximum analog and digital record length of 10 Mpoints.
The MSO4104B doubles this capability, providing a standard 20 Mpoints record length. This expanded record length is particularly useful for debugging long-duration protocol sequences or low-frequency system events while retaining a high sample rate.
Physical Dimensions and Electrical Safety
All four models share a similar form factor and use a 10.4-inch XGA color TFT display. However, there are small variations in depth and safety ratings:
- Chassis Depth: The MSO4034, MSO4054, and MSO4104 have a depth of 137 mm, whereas the MSO4104B is deeper at 147 mm.
- Electrical Tolerances: The maximum input voltage on a 1 MΩ input for the MSO4034 is 250 Vrms CAT I. The MSO4104B is rated for 300 Vrms CAT II.
- Cooling: The MSO4104 and MSO4104B require a 51 mm (2-inch) cooling clearance on the left side and rear of the unit during operation.
Frequently asked questions
