Jitter and Eye Diagram Analysis

Optional jitter analysis (MSO8000HD-JITTER) decomposes timing jitter into random and deterministic components, generates eye diagrams, and measures bit error rate. Essential for validating high-speed serial interfaces such as USB, PCIe, Ethernet, and custom links, where timing margins determine compliance.

Automated Compliance Testing

Optional compliance test packages automate the measurement sequences required for USB 2.0 and 10/100 Ethernet physical layer compliance. Predefined test plans guide the operator through setup, execute the measurements, and generate pass/fail reports which significantly reduce the time and expertise required for compliance verification.

MATLAB and Automation Integration

Optional MATLAB integration (MSO8000HD-MAT) enables scripted measurement workflows, custom analysis algorithms, and automated test sequences. Combined with SCPI control over USB and LAN, the MSO8804HD integrates into production test systems and research automation environments.

Questions and Answers

Does the MSO8804HD include a signal generator?
The AWG is available as an optional software license (MSO8000HD-AWG). It provides a 50 MHz dual-channel function/arbitrary waveform generator enabling stimulus-response testing without external equipment.

Will the MSO8804HD give the full 8 GHz bandwidth on all four channels?
The full 8 GHz bandwidth is only available in optimized dual‑channel mode (C1, C3, or C1+C3). When all four channels are active, the bandwidth drops to 4 GHz.

How does the sampling rate behave with different channel configurations?
Short answer, 20 GSa/s is available only in optimized dual‑channel mode. With all four channels enabled the oscilloscope runs at 10 GSa/s, the MSO8804HD dynamically halves the sample rate when all channels are active.

What is the advantage of 12-bit resolution?
A 12‑bit ADC delivers 4,096 vertical quantization steps, far more than the 256 levels of an 8‑bit system, that's a 16x increase in resolution. This added precision makes it easier to see small signals riding on top of larger ones, cuts down on quantization noise, and boosts accuracy when measuring low‑level phenomena such as power‑supply ripple, sensor outputs, or other fine analog details.
