Description
Overview
The Keysight 54754A is a two-channel, 18-GHz TDR/TDT (Time Domain Reflectometry/Transmission) module designed for advanced signal integrity testing. The two channels can operate independently or in tandem to provide differential or common-mode stimulus and response measurements. Each channel functions as a normal oscilloscope vertical system when the TDR/TDT step generators are not active, providing versatile measurement capabilities for high-bandwidth applications.
Key Features
- Two 18-GHz channels with built-in TDR step generators
- Configurable for 1-port, 2-port common-mode, or 2-port differential TDR/TDT measurements
- Low characteristic rms noise: 0.25 mV (12.4 GHz BW), 0.5 mV (18 GHz BW)
- Maximum input signal: ±2 Vdc
- Built-in TDR/TDT calibration with user-selectable edge speed
- S-parameters support (requires mainframe firmware A.06.01 or later with option 202)
Applications
- Signal integrity analysis on printed circuit boards
- Cable and transmission line characterization
- Device impedance and reflection measurements
- High-speed digital circuit debugging
