Overview and Features

HIGHLIGHTS

Comprehensive measurement and debug solution

Performs PAM-4 measurements as outlined in draft documents for OIF-CEI 4.0 and IEEE 400G (P802.3bs)
Performs more than 25 tests
Level-based (noise, linearity), eye-based (EW6, EH6), jitter, and return loss tests

Flexible and extensible

Operates on 86100D DCA-X oscilloscopes or your personal computer
Control your device under test (DUT) and other equipment
Test all or selected parameters to compliance limits (proposed in draft specification document) or custom limits

Compatibility

86100D Infiniium DCA-X mainframe

Reduce your test time from hours to minutes. Use the Keysight N1085A software application with your 86100D DCA-X Series oscilloscope to measure your Pulse Amplitude Modulation 4-Level (PAM-4) design according to the measurements outlined in draft standards such as:

OIF-CEI-56G-VSR-PAM4 Very Short Reach Interface
IEEE 400G (P802.3bs)

Performs more than 25 tests including:

Level-based measurements (using linearity pattern)
- Voltage levels
- Level thickness (rms)
- Level separation mismatch ratio (RLM), including Smin, Vavg, ES1, ES2
Output voltage tests
- Differential pk-pk (Tx enabled/disabled)
- AC common-mode output voltage
- DC common-mode output voltage
Output waveform measurements
- Steady-state voltage, Vf
- Linear fit pulse peak
- Signal-to-noise-and-distortion ratio (SNDR)
- Normalized coefficient step size
- Full-scale range tests
Return loss measurements using N1055A TDR or ENA/PNA
