What is the difference in record length between standard and B-series models?

Standard models such as the DPO4104, DPO4054, DPO4034, and DPO4032 feature a standard 10 Mpoint record length. The B-series models (DPO4104B and DPO4034B) feature a 20 Mpoint record length on all channels.

Which models support 11-bit vertical resolution?

The B-series models, specifically the DPO4104B and DPO4034B, support a Hi Res mode that extends vertical resolution from the baseline 8 bits up to 11 bits.

Are there differences in physical size between the models?

Most models share identical dimensions of 439 mm in width, 229 mm in height, and 137 mm in depth. The DPO4104B has a slightly increased depth of 147 mm. All models weigh 5.0 kg.

Bandwidth and Rise Time Capabilities

The series spans three distinct bandwidth levels to accommodate different signal speeds and rise time requirements. The high-performance 1 GHz models, which include the DPO4104 and the DPO4104B, are built for high-speed digital circuitry and offer a quick calculated rise time of 350 ps coupled with a 5 GS/s real-time sample rate.

For mid-range requirements, the DPO4054 operates at 500 MHz bandwidth with a 700 ps rise time. General-purpose troubleshooting is handled by the 350 MHz models, comprising the DPO4032, DPO4034, and DPO4034B, which provide a 1 ns rise time and a 2.5 GS/s sampling rate on all channels.

Comparing Standard and B-Series Specifications

The primary evolution from the standard DPO4000 models to the MSO/DPO4000B series is found in record length, resolution enhancement, and connectivity speed:

Record Length: Standard instruments like the DPO4104, DPO4054, DPO4034, and DPO4032 are equipped with a standard 10 Mpoint record length on all channels. The newer DPO4104B and DPO4034B double this capacity to 20 Mpoints per channel, permitting longer capture times.
Vertical Resolution: While all models utilize an 8-bit analog-to-digital converter, the B-series units feature a Hi Res mode that can increase effective vertical resolution up to 11 bits.
Network Interfaces: Standard models provide 10/100 Base-T Ethernet, whereas the B-series units support faster gigabit (10/100/1000 Mb/s) LAN connections.

Channel Architecture and Inputs

Most models in this series are 4-channel instruments, making them suitable for multi-point tracking in complex bus configurations. For simpler debugging tasks or budget-constrained setups, the DPO4032 provides a 2-channel variant at 350 MHz.

Every model in this range supports dual input impedance levels of 1 MΩ and 50 Ω, with input coupling options including AC and DC (and GND on select models). This allows direct connection to a variety of probe types and signal sources while maintaining signal integrity.
