The Keysight (Agilent) N1045A is a 60 GHz electrical remote sampling head designed for high-speed electrical signal acquisition within the N1000A DCA-X oscilloscope mainframe. This module places sampling electronics close to the device under test, minimizing signal degradation and cabling artifacts that compromise measurement fidelity. Each N1045A occupies one of four available module slots and provides user-selectable channel configurations and bandwidth settings to match specific test requirements.
Technical Specifications
• Bandwidth: 60 GHz (65 GHz typical)
• User-Selectable Bandwidth Settings: 60 GHz, 45 GHz, 35 GHz, 20 GHz
• Channel Configuration: 2 or 4 channels per module, user-selectable
• Electrical Input Connectors: 1.85 mm male or female (user-selectable)
• Maximum Input Voltage: ±2 V
• Connector Torque Limit: 5 in-lb (0.57 Nm) for 1.85 mm connectors
• Temperature Stability Range: ±5°C from last calibration
• Firmware Requirement: Minimum FlexDCA A.02.00
– Key Features
• Remote head architecture reduces measurement uncertainty by eliminating extended signal paths
• Signal scaling, bandwidth limiting, and offset adjustment on board
• Four connector variants: 02M/02F (2-channel), 04M/04F (4-channel) with male/female options
• Analog output to acquisition board ADCs within the mainframe
• Mechanical cable stabilization recommended to minimize phase shift effects
– Typical Applications
• Optical transceiver design and production testing
• Electrical ASIC, FPGA, and IC design characterization
• Serial bus measurements and validation
• TDR/TDT and S-parameter characterization of channels, cables, and PCBs
– Compatibility & Integration
The N1045A integrates exclusively with the Keysight N1000A DCA-X mainframe platform, requiring minimum firmware version A.02.00 for full operational support.
