N1046A Keysight Electrical Remote Sampling Head Module

Keysight N1046A Electrical Remote Sampling Head Module

Product Overview
The Keysight N1046A is a high-performance electrical remote sampling head module developed by Keysight Technologies, designed for high-speed digital communications, optical communications, and precision signal integrity testing. Compatible with Keysight 86100D or N1000A series mainframes, this module delivers exceptional signal acquisition and analysis capabilities, making it ideal for testing PAM4/NRZ signals at 56 Gbaud and beyond.

Key Features

1. Ultra-Wide Bandwidth & Low Noise

• Supports 75 GHz, 85 GHz, or >100 GHz (upgradable) bandwidth options, meeting the testing demands of 224 Gb/s (112 GBd PAM4) and higher-speed signals.

• Low-noise sampling technology ensures high-precision measurements for high-speed SerDes, optical modules, and coherent communication analysis.

2. Flexible Channel Configuration

• Offers 1, 2, or 4 channels (user-selectable), enabling multi-channel synchronous measurements for differential signals or parallel link analysis.

3. High-Precision Electrical Interface

• Input interface features a 1.0 mm female connector (includes 1.0 mm to 1.85 mm adapter), compatible with high-frequency probes and cables to maintain signal integrity.

• 250 kSa/s sampling rate combined with high linearity design ensures accurate capture of fast edges and transient signals.

4. Remote Sampling Technology

• Utilizes optical fiber for remote connection to the mainframe, minimizing transmission loss and interference—ideal for complex test environments (e.g., optical module production lines or labs).

5. Pulse Response Correction (PRC)

• Supports PRC for all channels (optical/electrical), eliminating system-inherent distortion to enhance measurement accuracy.

6. Compatibility & Scalability

• Compatible with 86100D (40 kSa/s) and N1000A (250 kSa/s) mainframes, protecting existing user investments.

• Works seamlessly with Keysight DCA-X or Infiniium UXR series oscilloscope software for automated TDECQ, eye diagram, and jitter analysis.

Typical Applications

• High-Speed Digital Communications: 56G/112G PAM4, NRZ signal testing (e.g., 400G/800G Ethernet, PCIe 6.0).

• Optical Module Development: Coherent optical communication, DSP equalization analysis, and TDECQ measurements.

• Signal Integrity Validation: Loss and crosstalk evaluation in packages, PCBs, or high-speed interconnects.
